9ddd2b8d1a LoongArch: BPF: Support 32-bit offset jmp instructions
Add support for 32-bit offset jmp instruction. Currently, we use b
instruction which supports range within ±128MB for such jumps. This
should be large enough for BPF progs.

4ebf9216e7 LoongArch: BPF: Support unconditional bswap instructions
Add support for unconditional bswap instruction. Since LoongArch is
always little-endian, just treat unconditional bswap the same as big-
endian conversion.

71945968d8 LoongArch: Mark __percpu functions as always inline
A recent change to the optimization pipeline in LLVM reveals some
fragility around the inlining of LoongArch's __percpu functions, which
manifests as a BUILD_BUG() failure:

  1 error generated.

If these functions are not inlined (which the compiler is free to do
even with functions marked with the standard 'inline' keyword), the
BUILD_BUG() in the default case cannot be eliminated since the compiler
cannot prove it is never used, resulting in a build failure due to the
error attribute.

Mark these functions as __always_inline to guarantee inlining so that
the BUILD_BUG() only triggers when the default case genuinely cannot be
eliminated due to an unexpected size.

21eb2bfe27 LoongArch: Disable module from accessing external data directly
The distance between vmlinux and the module is too far so that PC-REL
cannot be accessed directly, only GOT.

When compiling module with GCC, the option `-mdirect-extern-access` is
disabled by default. The Clang option `-fdirect-access-external-data` is
enabled by default, so it needs to be explicitly disabled.

80c7889de7 LoongArch: Support PREEMPT_DYNAMIC with static keys
Since commit 4e90d0522a ("riscv: support PREEMPT_DYNAMIC with
static keys"), the infrastructure is complete and we can simply select
HAVE_PREEMPT_DYNAMIC_KEY to enable PREEMPT_DYNAMIC on LoongArch because
we already support static keys.

926fe783c8 tracing/kprobes: Fix symbol counting logic by looking at modules as well
Recent changes to count number of matching symbols when creating
a kprobe event failed to take into account kernel modules. As such, it
breaks kprobes on kernel module symbols, by assuming there is no match.

Fix this my calling module_kallsyms_on_each_symbol() in addition to
kallsyms_on_each_match_symbol() to perform a proper counting.

1939316bf9 io_uring: kiocb_done() should *not* trust ->ki_pos if ->{read,write}_iter() failed
->ki_pos value is unreliable in such cases.  For an obvious example,
consider O_DSYNC write - we feed the data to page cache and start IO,
then we make sure it's completed.  Update of ->ki_pos is dealt with
by the first part; failure in the second ends up with negative value
returned _and_ ->ki_pos left advanced as if sync had been successful.
In the same situation write(2) does not advance the file position
at all.

1f36cd05e0 sparc32: fix a braino in fault handling in csum_and_copy_..._user()
Fault handler used to make non-trivial calls, so it needed
to set a stack frame up.  Used to be
	save ... - grab a stack frame, old %o... become %i...
	....
	ret	- go back to address originally in %o7, currently %i7
	 restore - switch to previous stack frame, in delay slot
Non-trivial calls had been gone since ab5e8b3312 and that code should
have become
	retl	- go back to address in %o7
	 clr %o0 - have return value set to 0
What it had become instead was
	ret	- go back to address in %i7 - return address of *caller*
	 clr %o0 - have return value set to 0
which is not good, to put it mildly - we forcibly return 0 from
csum_and_copy_{from,to}_iter() (which is what the call of that
thing had been inlined into) and do that without dropping the
stack frame of said csum_and_copy_..._iter().  Confuses the
hell out of the caller of csum_and_copy_..._iter(), obviously...

   Possible unsafe locking scenario:

       lock(watchdog_lock);

    run_timer_softirq+0x2a/0x50
    sysvec_apic_timer_interrupt+0x6e/0x90

The reason is the recent conversion of the TSC synchronization function
during CPU hotplug on the control CPU to a SMP function call. In case
that the synchronization with the upcoming CPU fails, the TSC has to be
marked unstable via clocksource_mark_unstable().

clocksource_mark_unstable() acquires 'watchdog_lock', but that lock is
taken with interrupts enabled in the watchdog timer callback to minimize
interrupt disabled time. That's obviously a possible deadlock scenario,

Before that change the synchronization function was invoked in thread
context so this could not happen.

As it is not crucical whether the unstable marking happens slightly
delayed, defer the call to a worker thread which avoids the lock context
problem.

128b0c9781 x86/i8259: Skip probing when ACPI/MADT advertises PCAT compatibility
David and a few others reported that on certain newer systems some legacy
interrupts fail to work correctly.

Debugging revealed that the BIOS of these systems leaves the legacy PIC in
uninitialized state which makes the PIC detection fail and the kernel
switches to a dummy implementation.

Unfortunately this fallback causes quite some code to fail as it depends on
checks for the number of legacy PIC interrupts or the availability of the
real PIC.

In theory there is no reason to use the PIC on any modern system when
IO/APIC is available, but the dependencies on the related checks cannot be
resolved trivially and on short notice. This needs lots of analysis and
rework.

The PIC detection has been added to avoid quirky checks and force selection
of the dummy implementation all over the place, especially in VM guest
scenarios. So it's not an option to revert the relevant commit as that
would break a lot of other scenarios.

One solution would be to try to initialize the PIC on detection fail and
retry the detection, but that puts the burden on everything which does not
have a PIC.

Fortunately the ACPI/MADT table header has a flag field, which advertises
in bit 0 that the system is PCAT compatible, which means it has a legacy
8259 PIC.

Evaluate that bit and if set avoid the detection routine and keep the real
PIC installed, which then gets initialized (for nothing) and makes the rest
of the code with all the dependencies work again.

3bde7ec13c platform/x86: Add s2idle quirk for more Lenovo laptops
When suspending to idle and resuming on some Lenovo laptops using the
Mendocino APU, multiple NVME IOMMU page faults occur, showing up in
dmesg as repeated errors:

nvme 0000:01:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x000b
address=0xb6674000 flags=0x0000]

The system is unstable afterwards.

Applying the s2idle quirk introduced by commit 455cd867b8 ("platform/x86:
thinkpad_acpi: Add a s2idle resume quirk for a number of laptops")
allows these systems to work with the IOMMU enabled and s2idle
resume to work.

24eca2dce0 scsi: sd: Introduce manage_shutdown device flag
Commit aa3998dbeb ("ata: libata-scsi: Disable scsi device
manage_system_start_stop") change setting the manage_system_start_stop
flag to false for libata managed disks to enable libata internal
management of disk suspend/resume. However, a side effect of this change
is that on system shutdown, disks are no longer being stopped (set to
standby mode with the heads unloaded). While this is not a critical
issue, this unclean shutdown is not recommended and shows up with
increased smart counters (e.g. the unexpected power loss counter
"Unexpect_Power_Loss_Ct").

Instead of defining a shutdown driver method for all ATA adapter
drivers (not all of them define that operation), this patch resolves
this issue by further refining the sd driver start/stop control of disks
using the new flag manage_shutdown. If this new flag is set to true by
a low level driver, the function sd_shutdown() will issue a
START STOP UNIT command with the start argument set to 0 when a disk
needs to be powered off (suspended) on system power off, that is, when
system_state is equal to SYSTEM_POWER_OFF.

Similarly to the other manage_xxx flags, the new manage_shutdown flag is
exposed through sysfs as a read-write device attribute.

To avoid any confusion between manage_shutdown and
manage_system_start_stop, the comments describing these flags in
include/scsi/scsi.h are also improved.

Fixes: aa3998dbeb ("ata: libata-scsi: Disable scsi device manage_system_start_stop")

Pull ARM SoC fixes from Arnd Bergmann:
 "A couple of platforms have some last-minute fixes, in particular:

   - riscv gets some fixes for noncoherent DMA on the renesas and thead
     platforms and dts fix for SPI on the visionfive 2 board

   - Qualcomm Snapdragon gets three dts fixes to address board specific
     regressions on the pmic and gpio nodes

   - Rockchip platforms get multiple dts fixes to address issues on the
     recent rk3399 platform as well as the older rk3128 platform that
     apparently regressed a while ago.

   - TI OMAP gets some trivial code and dts fixes and a regression fix
     for the omap1 ams-delta modem

   - NXP i.MX firmware has one fix for a use-after-free but in its error
     handling"

b132ac51d7 accel/ivpu/37xx: Fix missing VPUIP interrupts
Move sequence of masking and unmasking global interrupts from buttress
interrupt handler to generic one that handles both VPUIP and BTRS
interrupts. Unmasking global interrupts will re-trigger MSI for any
pending interrupts.

Lack of this sequence will cause the driver to miss any
VPUIP interrupt that comes after reading VPU_37XX_HOST_SS_ICB_STATUS_0
and before clearing all active interrupt sources.

5379866664 iavf: in iavf_down, disable queues when removing the driver
In iavf_down, we're skipping the scheduling of certain operations if
the driver is being removed. However, the IAVF_FLAG_AQ_DISABLE_QUEUES
request must not be skipped in this case, because iavf_close waits
for the transition to the __IAVF_DOWN state, which happens in
iavf_virtchnl_completion after the queues are released.

Without this fix, "rmmod iavf" takes half a second per interface that's
up and prints the "Device resources not yet released" warning.
