The "probe_setup_failed" label calls pm_runtime_disable(), but
pm_runtime_enable() was placed after a possible jump to this label.
When cqspi_setup_flash() fails, control jumps to the label without
pm_runtime_enable() being called, leading to unbalanced PM runtime
reference counting.
Move pm_runtime_enable() and associated calls above the first
possible branch to "probe_setup_failed" to ensure balanced
enable/disable calls across all error paths.

Add a TODO comment that ideally the ACPI/gpiolib core code should take care
of setting GPIO direction and/or bias according to ACPI GPIO resources.
If this TODO gets implemented then the acpi_dev_gpio_irq_get() call in
acpi_register_spi_device() can be dropped.

SPI devices using a (relative) slow frequency need a larger time.
For instance, microblaze running at 83.25MHz and performing a
3 bytes transaction using a 10MHz/16 = 625kHz needed this stall
value increased to at least 20. The SPI device is quite slow, but
also is the microblaze, so set this value to 32 to give it even
more margin.

Since sdma hardware configure postpone to transfer phase, have to disable
dma request before dma transfer setup because there is a hardware
limitation on sdma event enable(ENBLn) as below:
"It is thus essential for the Arm platform to program them before any DMA
request is triggered to the SDMA, otherwise an unpredictable combination
of channels may be started."

Since commit d24cfee7f63d ("spi: Fix acpi deferred irq probe"), the
acpi_dev_gpio_irq_get() call gets delayed till spi_probe() is called
on the SPI device.
If there is no driver for the SPI device then the move to spi_probe()
results in acpi_dev_gpio_irq_get() never getting called. This may
cause problems by leaving the GPIO pin floating because this call is
responsible for setting up the GPIO pin direction and/or bias according
to the values from the ACPI tables.
Re-add the removed acpi_dev_gpio_irq_get() in acpi_register_spi_device()
to ensure the GPIO pin is always correctly setup, while keeping the
acpi_dev_gpio_irq_get() call added to spi_probe() to deal with
-EPROBE_DEFER returns caused by the GPIO controller not having a driver
yet.

If an insn->alt points to a STAC/CLAC instruction, skip_alt_group()
assumes it's part of an alternative ("alt group") as opposed to some
other kind of "alt" such as an exception fixup.
While that assumption may hold true in the current code base, Linus has
an out-of-tree patch which breaks that assumption by replacing the
STAC/CLAC alternatives with raw STAC/CLAC instructions.
Make skip_alt_group() more robust by making sure it's actually an alt
group before continuing.

With full LTO, it is possible for LLVM to realize that these functions never
have their address taken (as they are only used within an alternative, which
will make them a direct call) across the whole kernel and either drop or skip
generating their kCFI type identification symbols.
clear_page_{rep,orig,erms}() are defined in clear_page_64.S with
SYM_TYPED_FUNC_START as a result of
2981557cb040 ("x86,kcfi: Fix EXPORT_SYMBOL vs kCFI"),
as exported functions are free to be called indirectly thus need kCFI type
identifiers.
Use KCFI_REFERENCE with these clear_page() functions to force LLVM to see
these functions as address-taken and generate then keep the kCFI type
identifiers.

pbus_size_mem() should only be called for bridge windows that exist but
__pci_bus_size_bridges() may point 'pref' to a resource that does not exist
(has zero flags) in case of non-root buses.
When prefetchable bridge window does not exist, the same non-prefetchable
bridge window is sized more than once which may result in duplicating
entries into the realloc_head list. Duplicated entries are shown in this
log and trigger a WARN_ON() because realloc_head had residual entries after
the resource assignment algorithm:

This reverts commit a729c16646198872e345bf6c48dbe540ad8a9753.
Prior to a729c1664619 ("PCI: qcom: Remove custom ASPM enablement code"),
the qcom controller driver enabled ASPM, including L0s, L1, and L1 PM
Substates, for all devices powered on at the time the controller driver
enumerates them.
ASPM was *not* enabled for devices powered on later by pwrctrl (unless the
kernel was built with PCIEASPM_POWERSAVE or PCIEASPM_POWER_SUPERSAVE, or
the user enabled ASPM via module parameter or sysfs).
After f3ac2ff14834 ("PCI/ASPM: Enable all ClockPM and ASPM states for
devicetree platforms"), the PCI core enabled all ASPM states for all
devices whether powered on initially or by pwrctrl, so a729c1664619 was
unnecessary and reverted.
But f3ac2ff14834 was too aggressive and broke platforms that didn't support
CLKREQ# or required device-specific configuration for L1 Substates, so
df5192d9bb0e ("PCI/ASPM: Enable only L0s and L1 for devicetree platforms")
enabled only L0s and L1.
On Qualcomm platforms, this left L1 Substates disabled, which was a
regression. Revert a729c1664619 so L1 Substates will be enabled on devices
that are initially powered on. Devices powered on by pwrctrl will be
addressed later.

The arm64 JIT supports BPF_ST with BPF_PROBE_MEM32 (arena) by using the
tmp2 register to hold the dst + arena_vm_base value and using tmp2 as the
new dst register. But this is broken because in case is_lsi_offset()
returns false the tmp2 will be clobbered by emit_a64_mov_i(1, tmp2, off,
ctx); and hence the emitted store instruction will be of the form:
strb w10, [x11, x11]
Fix this by using the third temporary register to hold the dst +
arena_vm_base.

Two functions with identical names but different addresses are

Later resolve_btfids warns since it cannot find them.
Commit 378b7708194f ("sched: Make migrate_{en,dis}able() inline") made
them inlineable in most places, but in vmlinux built with llvm 21 and 22
there are four symbols for migrate_{enable,disable}:
three static functions and one global function.
Fix the issue by marking migrate_{enable,disable} as always inline.
The alternative is to mark them as notrace/nokprobe which is more
drastic. Only bpf programs are prevented from attaching to these
functions. The rest of the tracing shouldn't be affected.
[note: Peter ok-ed the patch, Alexei rewrote commit log]

This driver assumes that bio vectors are memory aligned to the logical
block size, so set the queue limit to reflect that.
Unless we set up the limit based on the logical block size, we will go
out of page bounds in copy_to_nullb / copy_from_nullb.
Apparently this wasn't noticed so far because none of the tests generate
such buffers, but since commit 851c4c96db00 ("xfs: implement
XFS_IOC_DIOINFO in terms of vfs_getattr") xfstests generates unaligned
I/O, which now lead to memory corruption when using null_blk devices
with 4k block size.

ufs driver plus 2 core fixes. Once core fix makes the unit attention
counters atomic (just in case multiple commands detect them) and the
other is fixing a merge window regression caused by changes in the
block tree.

Besides blocks being invalidated, there is another case when the original
mapping could have changed between querying the rmap for GC and calling
xfs_zoned_map_extent. Document it there as it took us quite some time
to figure out what is going on while developing the multiple-GC
protection fix.

When we are picking a zone for gc it might already be in the pipeline
which can lead to us moving the same data twice resulting in in write
amplification and a very unfortunate case where we keep on garbage
collecting the zone we just filled with migrated data stopping all
forward progress.
Fix this by introducing a count of on-going GC operations on a zone, and
skip any zone with ongoing GC when picking a new victim.

boot. The driver's original commit 312fec1405dd ("drm: Initial KMS
