Qualcomm ARM64 updates for v6.4
PCI I/O and MEM ranges are corrected across all targets with PCIe
enabled. Likewise is CPU clocks defined to be provided from CPUfreq for
a wide range of platforms, to satisfy the OPP definitions, and LLCC bank
information is corrected for all relevant platforms.
IPQ5332 gains SMEM, CPUfreq and support for triggering download mode.
The MI01.2 board is introduced.
On MSM8916 WCN compatibles are moved to be defined per board, to avoid
issues when boards rely on the incorrect defaults. Support for Yiming
UZ801 4G modem stick is introduced.
XO clock is defined and fed to RPMCC on MSM8953 and MSM8976, to ensure
clock trees are properly rooted. DSI clocks feeding into gcc are
described on MSM8953.
On MSM8996 the external audio components are moved from the SoC dtsi. A
few DWC3 quirks are added.
On MSM8998 GPIO names are introduced for Sony Xperia XZ Premium, XZ1 and
XZ1 Compact. A numbe of boards have GPIO keys properly marked as
wakeup-source.
The SA8775P platform is extended with CPUfreq, UARTs, I2C controllers,
SPI controllers, SPMI and PMICs, PDC support. The associated PMICs gains
reset and power key support, as well as thermal zones defined. Nodes are
sorted. On top of this the SA8775P Ride board/platform is introduced.
On SC7180 and SC7280 a range of fixes coming from DeviceTree validation are
introduced, some clearing up unused properties, others correcting
errors. A number of Google rev0 boards on SC7180 are dropped, as these
are not considered to be in use by anyone anymore.
On SC8280XP RTC support is introduced and enabled for the CRD and Lenovo
Thinkpad X13s. It gains another UART, upon which Bluetooth is enabled on
the Lenovo ThinkPad X13s. The touchpad definition is altered to attempt
to probe both devices seen in the wild. A number of bug fixes are also
introduced, and the regulator definitions on X13s are corrected.
On SDM845 dynamic power coefficients are improved. BWMON compatible is
corrected. Xiaomi Pocophone F1 gains notification LED. Sony Xperia XZ2,
XZ2 Compact and XZ3 gains display, touchscreen, gpu and remoteproc
support. OnePlus 6 and 6T gains hall sensor.
GPU clock controller and remoteproc nodes are added for SM6115. CPU
clock are defined to come from CPUfreq. Board-specific USB-properties
are moved out of the SoC dtsi.
On SM6375 L3 scaling, IMEM, RMTFS, RPM sleep stats, Tsens, modem
remoteproc and WiFi nodes are added. Tsens thermal zones are defined and additional low power states
are defined. Sony Xperia 10 IV gains volume down key support.
On SM8150 another UART is introduced, to be used by GNSS on the SA8155
ADP. Support for the Flash LED block in PM8150L is added.
On SM8250 TPDM MM and PRNG is defined, MHI region is added to PCIe node.
A few bug fixes are introduced after Devicetree validation.
The DisplayPort controller on both SM8350 and SM8450 is defined and the
related QMP instance is transitioned to the USB3/DP combo variant. IMEM
and PIL info is introduced, for post mortem debugging of remoteprocs. On
the HDK PMIC GLINK is enabled and role switch is enabled. Some audio
resources are corrected.
A typo in the USB role property of the Microsoft Surface is corrected,
thanks to DeviceTree validation.
PCIe controllers and PHYs descriptions are corrected, and pinctrl state
definitions are moved from the soc to the board definition. BWMON
compatibles are corrected. PM8550B gains the definition of the eUSB2
repeater and this is enabled on the MTP. PMIC GLINK is also defined for
the MTP and connected to DWC3, for role switching support.
In addition to this, a range of cleanups based on Devicetree validation
is introduced.
A few clock bindings are introduced, from topic-branches shared with the
clock tree, to aid introduction of references to these.

'Unknown kernel command line parameters "nokaslr", will be passed to
user space' message is noticed in the dmesg when nokaslr is passed to
the kernel commandline on ARM64 platform. This is because nokaslr param
is handled by early cpufeature detection infrastructure and the parameter
is never consumed by a kernel param handler. Fix this warning by
providing a dummy kernel param handler for nokaslr.

Currently only the first attempt to single-step has any effect. After
that all further stepping remains "stuck" at the same program counter
value.
Refer to the ARM Architecture Reference Manual (ARM DDI 0487E.a) D2.12,
PSTATE.SS=1 should be set at each step before transferring the PE to the
'Active-not-pending' state. The problem here is PSTATE.SS=1 is not set
since the second single-step.
After the first single-step, the PE transferes to the 'Inactive' state,
with PSTATE.SS=0 and MDSCR.SS=1, thus PSTATE.SS won't be set to 1 due to
kernel_active_single_step()=true. Then the PE transferes to the
'Active-pending' state when ERET and returns to the debugger by step
exception.

A few more Qualcomm ARM64 DeviceTree fixes for 6.3
The GPIO polarity of the WSA881x shutdown GPIO was inconsistent and had
to be corrected in the driver, this fixes the polarity in the DeviceTree
for QRB5165 RB5, SM8250 MTP, Samsung Galaxy Book 2 and Lenovo Yoga C630.
The recent rearrangement of nodes among the IPQ8074 accidentally enabled
the PCIe PHYs, rather than the PCIe controllers. This is being
corrected, to restore PCIe functionality.
PMK8280 PON node has the wrong compatible, which recently caused the
driver to stop probing. This is corrected and the required "pbs" region
is added.
With support for HBR3 introduced, it's noted that SC7280 Herobrine
devices are having trouble running at this rate. This drops the claim
that it's supported, until further analysis can be done.

Now that we use XPACLRI to strip PACs within the kernel, the

longer need to live in <asm/compiler.h>.

Currently we strip the PAC from pointers using C code, which requires
generating bitmasks, and conditionally clearing/setting bits depending
on bit 55. We can do better by using XPACLRI directly.
When the logic was originally written to strip PACs from user pointers,
contemporary toolchains used for the kernel had assemblers which were
unaware of the PAC instructions. As stripping the PAC from userspace
pointers required unconditional clearing of a fixed set of bits (which
could be performed with a single instruction), it was simpler to
implement the masking in C than it was to make use of XPACI or XPACLRI.
When support for in-kernel pointer authentication was added, the
stripping logic was extended to cover TTBR1 pointers, requiring several
instructions to handle whether to clear/set bits dependent on bit 55 of
the pointer.
This patch simplifies the stripping of PACs by using XPACLRI directly,
as contemporary toolchains do within __builtin_return_address(). This
saves a number of instructions, especially where
__builtin_return_address() does not implicitly strip the PAC but is
heavily used (e.g. with tracepoints). As the kernel might be compiled
with an assembler without knowledge of XPACLRI, it is assembled using
the 'HINT #7' alias, which results in an identical opcode.
At the same time, I've split ptrauth_strip_insn_pac() into
ptrauth_strip_user_insn_pac() and ptrauth_strip_kernel_insn_pac()
helpers so that we can avoid unnecessary PAC stripping when pointer
authentication is not in use in userspace or kernel respectively.
The underlying xpaclri() macro uses inline assembly which clobbers x30.
The clobber causes the compiler to save/restore the original x30 value
in a frame record (protected with PACIASP and AUTIASP when in-kernel
authentication is enabled), so this does not provide a gadget to alter
the return address. Similarly this does not adversely affect unwinding
due to the presence of the frame record.
The ptrauth_user_pac_mask() and ptrauth_kernel_pac_mask() are exported
from the kernel in ptrace and core dumps, so these are retained. A
subsequent patch will move them out of <asm/compiler.h>.

In old versions of GCC and Clang, __builtin_return_address() did not
strip the PAC. This was not the behaviour we desired, and so we wrapped
this with code to strip the PAC in commit:
689eae42afd7a916 ("arm64: mask PAC bits of __builtin_return_address")
Since then, both GCC and Clang decided that __builtin_return_address()
*should* strip the PAC, and the existing behaviour was a bug.
GCC was fixed in 11.1.0, with those fixes backported to 10.2.0, 9.4.0,
8.5.0, but not earlier:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94891
Clang was fixed in 12.0.0, though this was not backported:
https://reviews.llvm.org/D75044
When using a compiler whose __builtin_return_address() strips the PAC,
our wrapper to strip the PAC is redundant. Similarly, when pointer
authentication is not in use within the kernel pointers will not have a
PAC, and so there's no point stripping those pointers.
To avoid this redundant work, this patch updates the
__builtin_return_address() wrapper to only be used when in-kernel
pointer authentication is configured and the compiler's
__builtin_return_address() does not strip the PAC.
This is a cleanup/optimization, and not a fix that requires backporting.
Stripping a PAC should be an idempotent operation, and so redundantly
stripping the PAC is not harmful.
There should be no functional change as a result of this patch.

commit 5944ce092b97 ("arch_topology: Build cacheinfo from primary CPU").
Previously, in the absence of any DT/ACPI cache info, architecture
specific cache detection and info allocation for secondary CPUs would
happen in non-preemptible context during early CPU initialization and
trigger a "BUG: sleeping function called from invalid context" splat on
an RT kernel.
This patch does not solve the problem completely for RT kernels. It
relies on the assumption that on most systems, the CPUs are symmetrical
and therefore have the same number of cache leaves. The cacheinfo memory
is allocated early (on the primary CPU), relying on the new handler. If
later (when CLIDR_EL1 based detection runs again on the secondary CPU)
the initial assumption proves to be wrong and the CPU has in fact more
leaves, the cacheinfo memory is reallocated, and that still triggers a
splat on an RT kernel.
In other words, asymmetrical CPU systems *must* still provide cacheinfo
data in DT/ACPI to avoid the splat on RT kernels (unless secondary CPUs
happen to have less leaves than the primary CPU). But symmetrical CPU
systems (the majority) can now get away without the additional DT/ACPI
data and rely on CLIDR_EL1 based detection.

SVE and SME are separate features which can be implemented without each
other but currently if the user specifies arm64.nosve then we disable SME
as well as SVE. There is already a separate override for SME so remove the

One usecase for this would be testing SME only support on a system which

memory zones
In commit 031495635b46 ("arm64: Do not defer reserve_crashkernel() for
platforms with no DMA memory zones"), reserve_crashkernel() is called
much earlier in arm64_memblock_init() to avoid causing base apge
mapping on platforms with no DMA meomry zones.
With taking off protection on crashkernel memory region, no need to call
reserve_crashkernel() specially in advance. The deferred invocation of
reserve_crashkernel() in bootmem_init() can cover all cases. So revert
the whole commit now.

Problem:
=======
On arm64, block and section mapping is supported to build page tables.
However, currently it enforces to take base page mapping for the whole
linear mapping if CONFIG_ZONE_DMA or CONFIG_ZONE_DMA32 is enabled and
crashkernel kernel parameter is set. This will cause longer time of the
linear mapping process during bootup and severe performance degradation
during running time.
Root cause:
==========
On arm64, crashkernel reservation relies on knowing the upper limit of
low memory zone because it needs to reserve memory in the zone so that
devices' DMA addressing in kdump kernel can be satisfied. However, the
upper limit of low memory on arm64 is variant. And the upper limit can
only be decided late till bootmem_init() is called [1].
And we need to map the crashkernel region with base page granularity when
doing linear mapping, because kdump needs to protect the crashkernel region
via set_memory_valid(,0) after kdump kernel loading. However, arm64 doesn't
support well on splitting the built block or section mapping due to some
cpu reststriction [2]. And unfortunately, the linear mapping is done before
bootmem_init().
To resolve the above conflict on arm64, the compromise is enforcing to
take base page mapping for the entire linear mapping if crashkernel is
set, and CONFIG_ZONE_DMA or CONFIG_ZONE_DMA32 is enabed. Hence
performance is sacrificed.
Solution:
=========
Comparing with the base page mapping for the whole linear region, it's
better to take off the protection on crashkernel memory region for the
time being because the anticipated stamping on crashkernel memory region
could only happen in a chance in one million, while the base page mapping
for the whole linear region is mitigating arm64 systems with crashkernel
set always.

Today the fixmap code largely maps elements at PAGE_SIZE granularity,
but we special-case the FDT mapping such that it can be mapped with 2M
block mappings when 4K pages are in use. The original rationale for this
was simplicity, but it has some unfortunate side-effects, and
complicates portions of the fixmap code (i.e. is not so simple after
all).
The FDT can be up to 2M in size but is only required to have 8-byte
alignment, and so it may straddle a 2M boundary. Thus when using 2M
block mappings we may map up to 4M of memory surrounding the FDT. This
is unfortunate as most of that memory will be unrelated to the FDT, and
any pages which happen to share a 2M block with the FDT will by mapped
with Normal Write-Back Cacheable attributes, which might not be what we
want elsewhere (e.g. for carve-outs using Non-Cacheable attributes).
The logic to handle mapping the FDT with 2M blocks requires some special
cases in the fixmap code, and ties it to the early page table
configuration by virtue of the SWAPPER_TABLE_SHIFT and
SWAPPER_BLOCK_SIZE constants used to determine the granularity used to
map the FDT.
This patch simplifies the FDT logic and removes the unnecessary mappings
of surrounding pages by always mapping the FDT at page granularity as
with all other fixmap mappings. To do so we statically reserve multiple
PTE tables to cover the fixmap VA range. Since the FDT can be at most
2M, for 4K pages we only need to allocate a single additional PTE table,
and for 16K and 64K pages the existing single PTE table is sufficient.
The PTE table allocation scales with the number of slots reserved in the
fixmap, and so this also makes it easier to add more fixmap entries if
we require those in future.
Our VA layout means that the fixmap will always fall within a single PMD
table (and consequently, within a single PUD/P4D/PGD entry), which we
can verify at compile time with a static_assert(). With that assert a
number of runtime warnings become impossible, and are removed.
I've boot-tested this patch with both 4K and 64K pages.

Currently arm64's FIXADDR_{START,SIZE} definitions only cover the
runtime fixmap slots (and not the boot-time fixmap slots), but the code
for creating the fixmap assumes that these definitions cover the entire
fixmap range. This means that the ptdump boundaries are reported in a
misleading way, missing the VA region of the runtime slots. In theory
this could also cause the fixmap creation to go wrong if the boot-time
fixmap slots end up spilling into a separate PMD entry, though luckily
this is not currently the case in any configuration.
While it seems like we could extend FIXADDR_{START,SIZE} to cover the
entire fixmap area, core code relies upon these *only* covering the
runtime slots. For example, fix_to_virt() and virt_to_fix() try to
reject manipulation of the boot-time slots based upon
FIXADDR_{START,SIZE}, while __fix_to_virt() and __virt_to_fix() can
handle any fixmap slot.
This patch follows the lead of x86 in commit:
55f49fcb879fbeeb ("x86/mm: Fix overlap of i386 CPU_ENTRY_AREA with FIX_BTMAP")
... and add new FIXADDR_TOT_{START,SIZE} definitions which cover the
entire fixmap area, using these for the fixmap creation and ptdump code.
As the boot-time fixmap slots are now rejected by fix_to_virt(),
the early_fixmap_init() code is changed to consistently use
__fix_to_virt(), as it already does in a few cases.

The arm64 stacktrace code can be used in kprobe context, and so cannot
be safely probed. Some (but not all) of the unwind functions are
annotated with `NOKPROBE_SYMBOL()` to ensure this, with others markes as
`__always_inline`, relying on the top-level unwind function being marked
as `noinstr`.
This patch has stacktrace.c consistently mark the internal stacktrace
functions as `__always_inline`, removing the need for NOKPROBE_SYMBOL()
as the top-level unwind function (arch_stack_walk()) is marked as
`noinstr`. This is more consistent and is a simpler pattern to follow
for future additions to stacktrace.c.

This builds up on the CALL_OPS work which extends the ftrace patchsite
on arm64 with an ops pointer usable by the ftrace trampoline.
This ops pointer is valid at all time. Indeed, it is either pointing to
ftrace_list_ops or to the single ops which should be called from that
patchsite.
There are a few cases to distinguish:
- If a direct call ops is the only one tracing a function:
- If the direct called trampoline is within the reach of a BL
instruction
-> the ftrace patchsite jumps to the trampoline
- Else
-> the ftrace patchsite jumps to the ftrace_caller trampoline which
reads the ops pointer in the patchsite and jumps to the direct
call address stored in the ops
- Else
-> the ftrace patchsite jumps to the ftrace_caller trampoline and its
ops literal points to ftrace_list_ops so it iterates over all
registered ftrace ops, including the direct call ops and calls its
call_direct_funcs handler which stores the direct called
trampoline's address in the ftrace_regs and the ftrace_caller
trampoline will return to that address instead of returning to the
traced function
