Provide an s390 specific word-at-a-time implementation. Compared to the
generic variant the generated code for has_zero() is slightly
better. However find_zero() is much simpler since it reuses the result
of __fls() aka flogr() and now comes without any conditional branches,
while the generic variant has three of them.

This patch introduces a new AP queue internal attribute
se_bound which reflects the bound state of an APQN within
a Secure Execution environment.
With introduction of Secure Execution guests now an
AP firmware queue needs to be bound to the guest before
usage. This patch introduces a new internal attribute
reflecting this bound state and some glue code to handle
this new field during lifetime of an AP queue device.
Together with that now the zcrypt scheduler considers
the state of the AP queues when a message is about to be
distributed among the existing queues. There is a new
function ap_queue_usable() which returns true only when
all conditions for using this AP queue device are fulfilled.
In details this means: the AP queue needs to be configured,
not checkstopped and within an SE environment it needs
to be bound. So the new function gives and indication
if the AP queue device is ready to serve requests or not.

On a state toggle from config off to config on and on the
state toggle from checkstop to not checkstop the queue's
internal states was set but the state machine was not
nudged. This did not care as on the first enqueue of a
request the state machine kick ran.
However, within an Secure Execution guest a queue is
only chosen by the scheduler when it has been bound.
But to bind a queue, it needs to run through the initial
states (reset, enable interrupts, ...). So this is like
a chicken-and-egg problem and the result was in fact
that a queue was unusable after a config off/on toggle.
With some slight rework of the handling of these states
now the new function _ap_queue_init_state() is called
which is the core of the ap_queue_init_state() function
but without locking handling. This has the benefit that
it can be called on all the places where a (re-)init
of the AP queue's state machine is needed.

Use system_ctl_load() instead of local_ctl_load() to reflect that
control register changes are supposed to be global.
Even though setup_cr() was ok, note that the usage of local_ctl_load()
would have been wrong, if it would have happened after the control
register save area was initialized: only local control register contents
would have been changed, but wouldn't be used for new CPUs.
With using system_ctl_load() the caller doesn't need to take care.

On s390, CPU 0 has special properties in comparison to other CPUs, as it
cannot be deconfigured for example. Therefore, allowing to hotplug CPU 0
introduces additional complexity when handling these properties.
Disallowing to hotplug CPU 0 allows to remove such complexities.
This follows x86 which also prevents offlining of CPU0 since commit
e59e74dc48a3 ("x86/topology: Remove CPU0 hotplug option").

Both the external call as well as the emergency signal submask bits in
control register 0 are set before any interrupt handler is registered.
Change the order and first register the interrupt handler and only then
enable the interrupts by setting the corresponding bits in control
register 0.
This prevents that the second part of the machine check handler for
early machine check handling is not executed: the machine check handler
sends an IPI to the CPU it runs on. If the corresponding interrupts are
enabled, but no interrupt handler is present, the interrupt is ignored.

The choose_32_64() macros were added to deal with an odd inconsistency
between the 32-bit and 64-bit layout of 'struct stat' way back when in
commit a52dd971f947 ("vfs: de-crapify "cp_new_stat()" function").
Then a decade later Mikulas noticed that said inconsistency had been a
mistake in the early x86-64 port, and shouldn't have existed in the
first place. So commit 932aba1e1690 ("stat: fix inconsistency between
struct stat and struct compat_stat") removed the uses of the helpers.
But the helpers remained around, unused.

The decompressor has a hard limit on the number of page tables it can
allocate. This limit is defined at compile-time and will cause boot
failure if it is reached.
The kernel is very strict and calculates the limit precisely for the
worst-case scenario based on the current configuration. However, it is
easy to forget to adjust the limit when a new use-case arises. The
worst-case scenario is rarely encountered during sanity checks.
In the case of enabling 5-level paging, a use-case was overlooked. The
limit needs to be increased by one to accommodate the additional level.
This oversight went unnoticed until Aaron attempted to run the kernel
via kexec with 5-level paging and unaccepted memory enabled.
Update wost-case calculations to include 5-level paging.
To address this issue, let's allocate some extra space for page tables.
128K should be sufficient for any use-case. The logic can be simplified
by using a single value for all kernel configurations.
[ Also add a warning, should this memory run low - by Dave Hansen. ]

Commit 408579cd627a ("mm: Update do_vmi_align_munmap() return
semantics") seems to have updated one of the callers of do_vmi_munmap()
incorrectly: it used to check for the error case (which didn't
change: negative means error).
That commit changed the check to the success case (which did change:
before that commit, 0 was success, and 1 was "success and lock
downgraded". After the change, it's always 0 for success, and the lock
will have been released if requested).
This didn't change any actual VM behavior _except_ for memory accounting
when 'VM_ACCOUNT' was set on the vma. Which made the wrong return value
test fairly subtle, since everything continues to work.
Or rather - it continues to work but the "Committed memory" accounting
goes all wonky (Committed_AS value in /proc/meminfo), and depending on
settings that then causes problems much much later as the VM relies on
bogus statistics for its heuristics.
Revert that one line of the change back to the original logic.

git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/libata
Pull ata fixes from Damien Le Moal:
- Fix link power management transitions to disallow unsupported states
(Niklas)
- A small string handling fix for the sata_mv driver (Christophe)
- Clear port pending interrupts before reset, as per AHCI
specifications (Szuying).
Followup fixes for this one are to not clear ATA_PFLAG_EH_PENDING in
ata_eh_reset() to allow EH to continue on with other actions recorded
with error interrupts triggered before EH completes. And an
additional fix to avoid thawing a port twice in EH (Niklas)
- Small code style fixes in the pata_parport driver to silence the
build bot as it keeps complaining about bad indentation (me)
- A fix for the recent CDL code to avoid fetching sense data for
successful commands when not necessary for correct operation (Niklas)

Pull USB fix from Greg KH:
"Here is a single USB fix for a much-reported regression for 6.6-rc1.
It resolves a crash in the typec debugfs code for many systems. It's
been in linux-next with no reported issues, and many people have
reported it resolving their problem with 6.6-rc1"

Pull driver core fixes from Greg KH:
"Here is a single driver core fix for a much-reported-by-sysbot issue
that showed up in 6.6-rc1. It's been submitted by many people, all in
the same way, so it obviously fixes things for them all.
Also in here is a single documentation update adding riscv to the
embargoed hardware document in case there are any future issues with
that processor family.
Both of these have been in linux-next with no reported problems"

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc fix from Greg KH:
"Here is a single patch for 6.6-rc2 that reverts a 6.5 change for the
comedi subsystem that has ended up being incorrect and caused drivers
that were working for people to be unable to be able to be selected to
build at all.
To fix this, the Kconfig change needs to be reverted and a future set
of fixes for the ioport dependancies will show up in 6.7-rc1 (there's
no rush for them.)
This has been in linux-next with no reported issues"
