Pull staging driver updates from Greg KH:
"Here is the big set of staging driver updates for 6.7-rc1. A bit
bigger than 6.6 this time around, as it coincided with the Outreachy
and mentorship application process, so we got a bunch of new
developers sending in their first changes, which is nice to see.
Also in here is a removal of the qlge ethernet driver, and the
rtl8192u wireless driver. Both of these were very old and no one was
maintaining them, the wireless driver removal was due to no one using
it anymore, and no hardware to be found, and is part of a larger
effort to remove unused and old wifi drivers from the system.
The qlge ethernet driver did have one user pop up after it was
dropped, and we are working with the network mainainers to figure out
what tree it will come back in from and who will be responsible for
it, and if it really is being used or not. Odds are it will show up in
a network subsystem pull request after -rc1 is out, but we aren't sure
yet.
Other smaller changes in here are:
- Lots of vc04_services work by Umang to clean up the mess created by
the rpi developers long ago, bringing it almost into good enough
shape to get out of staging, hopefully next major release, it's
getting close.
- rtl8192e variable cleanups and removal of unused code and
structures
- vme_user coding style cleanups
- other small coding style cleanups to lots of the staging drivers
- octeon typedef removals, and then last-minute revert when it was
found to break the build in some configurations (it's a hard driver
to build properly, none of the normal automated testing catches
it.)
All of these have been in linux-next for a while with no reported
issues"

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing updates from Steven Rostedt:
- Remove eventfs_file descriptor
This is the biggest change, and the second part of making eventfs
create its files dynamically.
In 6.6 the first part was added, and that maintained a one to one
mapping between eventfs meta descriptors and the directories and file
inodes and dentries that were dynamically created. The directories
were represented by a eventfs_inode and the files were represented by
a eventfs_file.
In v6.7 the eventfs_file is removed. As all events have the same
directory make up (sched_switch has an "enable", "id", "format", etc
files), the handing of what files are underneath each leaf eventfs
directory is moved back to the tracing subsystem via a callback.
When an event is added to the eventfs, it registers an array of
evenfs_entry's. These hold the names of the files and the callbacks
to call when the file is referenced. The callback gets the name so
that the same callback may be used by multiple files. The callback
then supplies the filesystem_operations structure needed to create
this file.
This has brought the memory footprint of creating multiple eventfs
instances down by 2 megs each!
- User events now has persistent events that are not associated to a
single processes. These are privileged events that hang around even
if no process is attached to them
- Clean up of seq_buf
There's talk about using seq_buf more to replace strscpy() and
friends. But this also requires some minor modifications of seq_buf
to be able to do this
- Expand instance ring buffers individually
Currently if boot up creates an instance, and a trace event is
enabled on that instance, the ring buffer for that instance and the
top level ring buffer are expanded (1.4 MB per CPU). This wastes
memory as this happens when nothing is using the top level instance
- Other minor clean ups and fixes

Pull kvm updates from Paolo Bonzini:
"ARM:
- Generalized infrastructure for 'writable' ID registers, effectively
allowing userspace to opt-out of certain vCPU features for its
guest
- Optimization for vSGI injection, opportunistically compressing
MPIDR to vCPU mapping into a table
- Improvements to KVM's PMU emulation, allowing userspace to select
the number of PMCs available to a VM
- Guest support for memory operation instructions (FEAT_MOPS)
- Cleanups to handling feature flags in KVM_ARM_VCPU_INIT, squashing
bugs and getting rid of useless code
- Changes to the way the SMCCC filter is constructed, avoiding wasted
memory allocations when not in use
- Load the stage-2 MMU context at vcpu_load() for VHE systems,
reducing the overhead of errata mitigations
- Miscellaneous kernel and selftest fixes
LoongArch:
- New architecture for kvm.
The hardware uses the same model as x86, s390 and RISC-V, where
guest/host mode is orthogonal to supervisor/user mode. The
virtualization extensions are very similar to MIPS, therefore the
code also has some similarities but it's been cleaned up to avoid
some of the historical bogosities that are found in arch/mips. The
kernel emulates MMU, timer and CSR accesses, while interrupt
controllers are only emulated in userspace, at least for now.
RISC-V:
- Support for the Smstateen and Zicond extensions
- Support for virtualizing senvcfg
- Support for virtualized SBI debug console (DBCN)
S390:
- Nested page table management can be monitored through tracepoints
and statistics
x86:
- Fix incorrect handling of VMX posted interrupt descriptor in
KVM_SET_LAPIC, which could result in a dropped timer IRQ
- Avoid WARN on systems with Intel IPI virtualization
- Add CONFIG_KVM_MAX_NR_VCPUS, to allow supporting up to 4096 vCPUs
without forcing more common use cases to eat the extra memory
overhead.
- Add virtualization support for AMD SRSO mitigation (IBPB_BRTYPE and
SBPB, aka Selective Branch Predictor Barrier).
- Fix a bug where restoring a vCPU snapshot that was taken within 1
second of creating the original vCPU would cause KVM to try to
synchronize the vCPU's TSC and thus clobber the correct TSC being
set by userspace.
- Compute guest wall clock using a single TSC read to avoid
generating an inaccurate time, e.g. if the vCPU is preempted
between multiple TSC reads.
- "Virtualize" HWCR.TscFreqSel to make Linux guests happy, which
complain about a "Firmware Bug" if the bit isn't set for select
F/M/S combos. Likewise "virtualize" (ignore) MSR_AMD64_TW_CFG to
appease Windows Server 2022.
- Don't apply side effects to Hyper-V's synthetic timer on writes
from userspace to fix an issue where the auto-enable behavior can
trigger spurious interrupts, i.e. do auto-enabling only for guest
writes.
- Remove an unnecessary kick of all vCPUs when synchronizing the
dirty log without PML enabled.
- Advertise "support" for non-serializing FS/GS base MSR writes as
appropriate.
- Harden the fast page fault path to guard against encountering an
invalid root when walking SPTEs.
- Omit "struct kvm_vcpu_xen" entirely when CONFIG_KVM_XEN=n.
- Use the fast path directly from the timer callback when delivering
Xen timer events, instead of waiting for the next iteration of the
run loop. This was not done so far because previously proposed code
had races, but now care is taken to stop the hrtimer at critical
points such as restarting the timer or saving the timer information
for userspace.
- Follow the lead of upstream Xen and ignore the VCPU_SSHOTTMR_future
flag.
- Optimize injection of PMU interrupts that are simultaneous with
NMIs.
- Usual handful of fixes for typos and other warts.
x86 - MTRR/PAT fixes and optimizations:
- Clean up code that deals with honoring guest MTRRs when the VM has
non-coherent DMA and host MTRRs are ignored, i.e. EPT is enabled.
- Zap EPT entries when non-coherent DMA assignment stops/start to
prevent using stale entries with the wrong memtype.
- Don't ignore guest PAT for CR0.CD=1 && KVM_X86_QUIRK_CD_NW_CLEARED=y
This was done as a workaround for virtual machine BIOSes that did
not bother to clear CR0.CD (because ancient KVM/QEMU did not bother
to set it, in turn), and there's zero reason to extend the quirk to
also ignore guest PAT.
x86 - SEV fixes:
- Report KVM_EXIT_SHUTDOWN instead of EINVAL if KVM intercepts
SHUTDOWN while running an SEV-ES guest.
- Clean up the recognition of emulation failures on SEV guests, when
KVM would like to "skip" the instruction but it had already been
partially emulated. This makes it possible to drop a hack that
second guessed the (insufficient) information provided by the
emulator, and just do the right thing.
Documentation:
- Various updates and fixes, mostly for x86
- MTRR and PAT fixes and optimizations"

Pull sh updates from John Paul Adrian Glaubitz:
"While the previously announced patch series for converting arch/sh to
device trees is not yet ready for inclusion to mainline and therefore
didn't make it for this pull request, there are still a small number
changes for v6.7 which include one platform (board plus CPU and driver
code) removal plus two fixes.
The removal sent in by Arnd Bergmann concerns the microdev board which
was an early SuperH prototype board that was never used in production.
With the board removed, we were able to drop the now unused code for
the SH4-202 CPU and well as the driver code for the superhyway bus and
a custom implementation for ioport_map() and ioport_unmap() which will
allow us to simplify ioport handling in the future.
Another patch set by Geert Uytterhoeven revives SuperH BIOS
earlyprintk support which got accidentally disabled in
e76fe57447e88916 ("sh: Remove old early serial console code V2"), the
second patch in the series updates the documentation.
Finally, a patch by Masami Hiramatsu fixes a regression reported by
the kernel test robot which uncovered that arch/sh is not implementing
arch_cmpxchg_local() and therefore needs use __generic_cmpxchg_local()
instead"

Pull sysctl updates from Luis Chamberlain:
"To help make the move of sysctls out of kernel/sysctl.c not incur a
size penalty sysctl has been changed to allow us to not require the
sentinel, the final empty element on the sysctl array. Joel Granados
has been doing all this work. On the v6.6 kernel we got the major
infrastructure changes required to support this. For v6.7-rc1 we have
all arch/ and drivers/ modified to remove the sentinel. Both arch and
driver changes have been on linux-next for a bit less than a month. It
is worth re-iterating the value:
- this helps reduce the overall build time size of the kernel and run
time memory consumed by the kernel by about ~64 bytes per array
- the extra 64-byte penalty is no longer inncurred now when we move
sysctls out from kernel/sysctl.c to their own files
For v6.8-rc1 expect removal of all the sentinels and also then the
unneeded check for procname == NULL.
The last two patches are fixes recently merged by Krister Johansen
which allow us again to use softlockup_panic early on boot. This used
to work but the alias work broke it. This is useful for folks who want
to detect softlockups super early rather than wait and spend money on
cloud solutions with nothing but an eventual hung kernel. Although
this hadn't gone through linux-next it's also a stable fix, so we
might as well roll through the fixes now"

Pull arm64 updates from Catalin Marinas:
"No major architecture features this time around, just some new HWCAP
definitions, support for the Ampere SoC PMUs and a few fixes/cleanups.
The bulk of the changes is reworking of the CPU capability checking
code (cpus_have_cap() etc).
- Major refactoring of the CPU capability detection logic resulting
in the removal of the cpus_have_const_cap() function and migrating
the code to "alternative" branches where possible
- Backtrace/kgdb: use IPIs and pseudo-NMI
- Perf and PMU:
- Add support for Ampere SoC PMUs
- Multi-DTC improvements for larger CMN configurations with
multiple Debug & Trace Controllers
- Rework the Arm CoreSight PMU driver to allow separate
registration of vendor backend modules
- Fixes: add missing MODULE_DEVICE_TABLE to the amlogic perf
driver; use device_get_match_data() in the xgene driver; fix
NULL pointer dereference in the hisi driver caused by calling
cpuhp_state_remove_instance(); use-after-free in the hisi driver
- HWCAP updates:
- FEAT_SVE_B16B16 (BFloat16)
- FEAT_LRCPC3 (release consistency model)
- FEAT_LSE128 (128-bit atomic instructions)
- SVE: remove a couple of pseudo registers from the cpufeature code.
There is logic in place already to detect mismatched SVE features
- Miscellaneous:
- Reduce the default swiotlb size (currently 64MB) if no ZONE_DMA
bouncing is needed. The buffer is still required for small
kmalloc() buffers
- Fix module PLT counting with !RANDOMIZE_BASE
- Restrict CPU_BIG_ENDIAN to LLVM IAS 15.x or newer move
synchronisation code out of the set_ptes() loop
- More compact cpufeature displaying enabled cores

Pull gpio updates from Bartosz Golaszewski:
"We don't have any new drivers. The loongson driver is getting extended
with support for new models. There's a big refactor of gpio-pca953x
and many small improvements to others.
The GPIO code in the kernel has acquired a lot of cruft over the years
as well as many abusers of the API across the kernel tree. This
release cycle we have started a major cleanup and improvement effort
that will most likely span several releases. We have started by
converting external users of struct gpio_chip to accessing the wrapper
around it - struct gpio_device. This is because the latter is
reference counted while the former is removed when the provider is
unbound. We also removed several instances of drivers accessing
private GPIOLIB structures and including the private header from
drivers/gpio/.
To that end you'll see several commits aimed at different subsystems
(acked by relevant maintainers) as well as two merges from the
x86/platform tree.
We'll then rework the locking in GPIOLIB which currently uses a big
spinlock for many different things and could use becoming more
fine-grained, especially as it doesn't even get the locking right.
We'll also use SRCU for protecting the gpio_chip pointer against
in-kernel hot-unplug crashes similar to what we saw triggered from
user-space and fixed with semaphores in gpiolib-cdev. The core GPIOLIB
is still vulnerable to these use-cases. I'm just mentioning the plans
here, this is not part of this PR.
You'll see some new instances of using __free(). We've added a
gpio_device_put cleanup helper similar to the put_device one
introduced by Peter Zijlstra and used it according to the preferred
pattern except where it didn't make sense.
GPIOLIB core:
- provide interfaces allowing users to retrieve, manage and query the
reference counted GPIO device instead of accessing the private
gpio_chip structure
- replace gpiochip_find() with gpio_device_find()
- remove unused acpi_get_and_request_gpiod()
- improve the ignore_interrupt functionality in GPIO ACPI
- correct notifier return codes in gpiolib-of
- unexport gpiod_set_transitory() as it's unused outside of core GPIO
code
- while there are still external users accessing struct gpio_chip,
let's make gpiochip_get_desc() public so that they at least use the
preferred helper
- improve locking for lookup tables
- annotate struct linereq with __counted_by
- improve GPIOLIB docs
- add an OF quirk for LED trigger sources
Driver improvements:
- convert all GPIO drivers with .remove() callbacks to using the new
variant returning void instead of int
- stop accessing the GPIOLIB private structures in gpio-mockup,
i2c-mux-gpio, hte-tegra194, gpio-sim
- use the recommended pattern for autofree variables in gpio-sim
- add support for more models to gpio-loongson
- use a notifier chain to notify other blocks about interrupts in
gpio-eic-sprd instead of looking up GPIO devices on every interrupt
- convert gpio-pca953x and gpio-fx6408 to using the maple tree regmap
cache
- don't include GPIOLIB internal headers in drivers which don't need
them
- move the ingenic NAND quirk into gpiolib-of
- add an ignore interrupt quirk for Peaq C1010
- drop static GPIO base from gpio-omap, gpio-f7188x
- use the preferred device_get_match_data() function in drivers that
still don't
- refactor gpio-pca953x: switch to using DEFINE_SIMPLE_DEV_PM_OPS(),
use cleanup helpers, use dev_err_probe() where it makes sense,
fully convert to using devres and some other minor tweaks
DT bindings:
- add support for a new model to gpio-vf610 and update existing
properties
- add support for more loongson models
- add missing support for imx models that are used but undocumented
- convert bindings for Intel IXP4xx to schema
Minor stuff:
- deprecate gpio-mockup in favor of gpio-sim
- include missing headers here and there
- stop using gpiochip_find() in OMAP1 board files
- minor tweaks in gpio-vf610, gpio-hisi
- remove unneeded 'extern' specifiers from headers"

the number of PMCs available to a VM
- Guest support for memory operation instructions (FEAT_MOPS)
- Cleanups to handling feature flags in KVM_ARM_VCPU_INIT, squashing
bugs and getting rid of useless code
- Changes to the way the SMCCC filter is constructed, avoiding wasted
memory allocations when not in use
- Load the stage-2 MMU context at vcpu_load() for VHE systems, reducing
the overhead of errata mitigations

- Support usec resolution of TCP timestamps, enabled selectively by a
route attribute.
- Defer regular TCP ACK while processing socket backlog, try to send
a cumulative ACK at the end. Increase single TCP flow performance
on a 200Gbit NIC by 20% (100Gbit -> 120Gbit).
- The Fair Queuing (FQ) packet scheduler:
- add built-in 3 band prio / WRR scheduling
- support bypass if the qdisc is mostly idle (5% speed up for TCP RR)
- improve inactive flow reporting
- optimize the layout of structures for better cache locality
- Support TCP Authentication Option (RFC 5925, TCP-AO), a more modern
replacement for the old MD5 option.
- Add more retransmission timeout (RTO) related statistics to
TCP_INFO.
- Support sending fragmented skbs over vsock sockets.
- Make sure we send SIGPIPE for vsock sockets if socket was
shutdown().
- Add sysctl for ignoring lower limit on lifetime in Router
Advertisement PIO, based on an in-progress IETF draft.
- Add sysctl to control activation of TCP ping-pong mode.
- Add sysctl to make connection timeout in MPTCP configurable.
- Support rcvlowat and notsent_lowat on MPTCP sockets, to help apps
limit the number of wakeups.
- Support netlink GET for MDB (multicast forwarding), allowing user
space to request a single MDB entry instead of dumping the entire
table.
- Support selective FDB flushing in the VXLAN tunnel driver.
- Allow limiting learned FDB entries in bridges, prevent OOM attacks.
- Allow controlling via configfs netconsole targets which were
created via the kernel cmdline at boot, rather than via configfs at
runtime.
- Support multiple PTP timestamp event queue readers with different
filters.
- MCTP over I3C.
BPF:
- Add new veth-like netdevice where BPF program defines the logic of
the xmit routine. It can operate in L3 and L2 mode.
- Support exceptions - allow asserting conditions which should never
be true but are hard for the verifier to infer. With some extra
flexibility around handling of the exit / failure:
https://lwn.net/Articles/938435/
- Add support for local per-cpu kptr, allow allocating and storing
per-cpu objects in maps. Access to those objects operates on the
value for the current CPU.
This allows to deprecate local one-off implementations of per-CPU
storage like BPF_MAP_TYPE_PERCPU_CGROUP_STORAGE maps.
- Extend cgroup BPF sockaddr hooks for UNIX sockets. The use case is
for systemd to re-implement the LogNamespace feature which allows
running multiple instances of systemd-journald to process the logs
of different services.
- Enable open-coded task_vma iteration, after maple tree conversion
made it hard to directly walk VMAs in tracing programs.
- Add open-coded task, css_task and css iterator support. One of the
use cases is customizable OOM victim selection via BPF.
- Allow source address selection with bpf_*_fib_lookup().
- Add ability to pin BPF timer to the current CPU.
- Prevent creation of infinite loops by combining tail calls and
fentry/fexit programs.
- Add missed stats for kprobes to retrieve the number of missed
kprobe executions and subsequent executions of BPF programs.
- Inherit system settings for CPU security mitigations.
- Add BPF v4 CPU instruction support for arm32 and s390x.
Changes to common code:
- overflow: add DEFINE_FLEX() for on-stack definition of structs with
flexible array members.
- Process doc update with more guidance for reviewers.
Driver API:
- Simplify locking in WiFi (cfg80211 and mac80211 layers), use wiphy
mutex in most places and remove a lot of smaller locks.
- Create a common DPLL configuration API. Allow configuring and
querying state of PLL circuits used for clock syntonization, in
network time distribution.
- Unify fragmented and full page allocation APIs in page pool code.
Let drivers be ignorant of PAGE_SIZE.
- Rework PHY state machine to avoid races with calls to phy_stop().
- Notify DSA drivers of MAC address changes on user ports, improve
correctness of offloads which depend on matching port MAC
addresses.
- Allow antenna control on injected WiFi frames.
- Reduce the number of variants of napi_schedule().
- Simplify error handling when composing devlink health messages.
Misc:
- A lot of KCSAN data race "fixes", from Eric.
- A lot of __counted_by() annotations, from Kees.
- A lot of strncpy -> strscpy and printf format fixes.
- Replace master/slave terminology with conduit/user in DSA drivers.

KVM SVM changes for 6.7:
- Report KVM_EXIT_SHUTDOWN instead of EINVAL if KVM intercepts SHUTDOWN while
running an SEV-ES guest.
- Clean up handling "failures" when KVM detects it can't emulate the "skip"
action for an instruction that has already been partially emulated. Drop a
hack in the SVM code that was fudging around the emulator code not giving
SVM enough information to do the right thing.
|
|
KVM PMU change for 6.7:
- Handle NMI/SMI requests after PMU/PMI requests so that a PMI=>NMI doesn't
require redoing the entire run loop due to the NMI not being detected until
the final kvm_vcpu_exit_request() check before entering the guest.
|
|
KVM x86 Xen changes for 6.7:
- Omit "struct kvm_vcpu_xen" entirely when CONFIG_KVM_XEN=n.
- Use the fast path directly from the timer callback when delivering Xen timer
events. Avoid the problematic races with using the fast path by ensuring
the hrtimer isn't running when (re)starting the timer or saving the timer
information (for userspace).
- Follow the lead of upstream Xen and ignore the VCPU_SSHOTTMR_future flag.
|
|
KVM x86 MMU changes for 6.7:
- Clean up code that deals with honoring guest MTRRs when the VM has
non-coherent DMA and host MTRRs are ignored, i.e. EPT is enabled.
- Zap EPT entries when non-coherent DMA assignment stops/start to prevent
using stale entries with the wrong memtype.
- Don't ignore guest PAT for CR0.CD=1 && KVM_X86_QUIRK_CD_NW_CLEARED=y, as
there's zero reason to ignore guest PAT if the effective MTRR memtype is WB.
This will also allow for future optimizations of handling guest MTRR updates
for VMs with non-coherent DMA and the quirk enabled.
- Harden the fast page fault path to guard against encountering an invalid
root when walking SPTEs.
|
|
KVM x86 misc changes for 6.7:
- Add CONFIG_KVM_MAX_NR_VCPUS to allow supporting up to 4096 vCPUs without
forcing more common use cases to eat the extra memory overhead.
- Add IBPB and SBPB virtualization support.
- Fix a bug where restoring a vCPU snapshot that was taken within 1 second of
creating the original vCPU would cause KVM to try to synchronize the vCPU's
TSC and thus clobber the correct TSC being set by userspace.
- Compute guest wall clock using a single TSC read to avoid generating an
inaccurate time, e.g. if the vCPU is preempted between multiple TSC reads.
- "Virtualize" HWCR.TscFreqSel to make Linux guests happy, which complain
about a "Firmware Bug" if the bit isn't set for select F/M/S combos.
- Don't apply side effects to Hyper-V's synthetic timer on writes from
userspace to fix an issue where the auto-enable behavior can trigger
spurious interrupts, i.e. do auto-enabling only for guest writes.
- Remove an unnecessary kick of all vCPUs when synchronizing the dirty log
without PML enabled.
- Advertise "support" for non-serializing FS/GS base MSR writes as appropriate.
- Use octal notation for file permissions through KVM x86.
- Fix a handful of typo fixes and warts.

|
KVM x86 APIC changes for 6.7:
- Purge VMX's posted interrupt descriptor *before* loading APIC state when
handling KVM_SET_LAPIC. Purging the PID after loading APIC state results in
lost APIC timer IRQs as the APIC timer can be armed as part of loading APIC
state, i.e. can immediately pend an IRQ if the expiry is in the past.
- Clear the ICR.BUSY bit when handling trap-like x2APIC writes. This avoids a
WARN, due to KVM expecting the BUSY bit to be cleared when sending IPIs.

LoongArch KVM changes for v6.7
Add LoongArch's KVM support. Loongson 3A5000/3A6000 supports hardware
assisted virtualization. With cpu virtualization, there are separate
hw-supported user mode and kernel mode in guest mode. With memory
virtualization, there are two-level hw mmu table for guest mode and host
mode. Also there is separate hw cpu timer with consant frequency in
guest mode, so that vm can migrate between hosts with different freq.
Currently, we are able to boot LoongArch Linux Guests.
Few key aspects of KVM LoongArch added by this series are:
1. Enable kvm hardware function when kvm module is loaded.
2. Implement VM and vcpu related ioctl interface such as vcpu create,
vcpu run etc. GET_ONE_REG/SET_ONE_REG ioctl commands are use to
get general registers one by one.
3. Hardware access about MMU, timer and csr are emulated in kernel.
4. Hardwares such as mmio and iocsr device are emulated in user space
such as IPI, irqchips, pci devices etc.

Pull rust updates from Miguel Ojeda:
"A small one compared to the previous one in terms of features. In
terms of lines, as usual, the 'alloc' version upgrade accounts for
most of them.

This time around, due to how the kernel and Rust schedules have
aligned, there are two upgrades in fact. They contain the fixes for
a few issues we reported to the Rust project.
In addition, a few cleanups indicated by the upgraded compiler or
possible thanks to it. For instance, the compiler now detects
redundant explicit links.

Pull x86 core updates from Thomas Gleixner:
- Limit the hardcoded topology quirk for Hygon CPUs to those which have
a model ID less than 4.
The newer models have the topology CPUID leaf 0xB correctly
implemented and are not affected.
- Make SMT control more robust against enumeration failures
SMT control was added to allow controlling SMT at boottime or
runtime. The primary purpose was to provide a simple mechanism to
disable SMT in the light of speculation attack vectors.
It turned out that the code is sensible to enumeration failures and
worked only by chance for XEN/PV. XEN/PV has no real APIC enumeration
which means the primary thread mask is not set up correctly. By
chance a XEN/PV boot ends up with smp_num_siblings == 2, which makes
the hotplug control stay at its default value "enabled". So the mask
is never evaluated.
The ongoing rework of the topology evaluation caused XEN/PV to end up
with smp_num_siblings == 1, which sets the SMT control to "not
supported" and the empty primary thread mask causes the hotplug core
to deny the bringup of the APS.
Make the decision logic more robust and take 'not supported' and 'not
implemented' into account for the decision whether a CPU should be
booted or not.
- Fake primary thread mask for XEN/PV
Pretend that all XEN/PV vCPUs are primary threads, which makes the
usage of the primary thread mask valid on XEN/PV. That is consistent
with because all of the topology information on XEN/PV is fake or
even non-existent.
- Encapsulate topology information in cpuinfo_x86
Move the randomly scattered topology data into a separate data
structure for readability and as a preparatory step for the topology
evaluation overhaul.
- Consolidate APIC ID data type to u32
It's fixed width hardware data and not randomly u16, int, unsigned
long or whatever developers decided to use.
- Cure the abuse of cpuinfo for persisting logical IDs.
Per CPU cpuinfo is used to persist the logical package and die IDs.
That's really not the right place simply because cpuinfo is subject
to be reinitialized when a CPU goes through an offline/online cycle.
Use separate per CPU data for the persisting to enable the further
topology management rework. It will be removed once the new topology
management is in place.
- Provide a debug interface for inspecting topology information
Useful in general and extremly helpful for validating the topology
management rework in terms of correctness or "bug" compatibility.

Pull x86 APIC updates from Thomas Gleixner:
- Make the quirk for non-maskable MSI interrupts in the affinity setter
functional again.
It was broken by a MSI core code update, which restructured the code
in a way that the quirk flag was not longer set correctly.
Trying to restore the core logic caused a deeper inspection and it
turned out that the extra quirk flag is not required at all because
it's the inverse of the reservation mode bit, which only can be set
when the MSI interrupt is maskable.
So the trivial fix is to use the reservation mode check in the
affinity setter function and remove almost 40 lines of code related
to the no-mask quirk flag.
- Cure a Kconfig dependency issue which causes compile failures by
correcting the conditionals in the affected header files.
- Clean up coding style in the UV APIC driver.
