Pull EFI fixes from Ard Biesheuvel:
"Take the newly introduced EFI_MEMORY_HOT_PLUGGABLE memory attribute
into account when placing the kernel image in memory at boot.
Otherwise, the presence of the kernel image could prevent such a

plugged', i.e., already plugged in at boot time (and exposed via the
EFI memory map).
This should ensure that the new EFI_MEMORY_HOT_PLUGGABLE memory
attribute is used consistently by Linux before it ever turns up in
production, ensuring that we can make meaningful use of it without
running the risk of regressing existing users"

The problem is that GCC expects 16-byte alignment of the incoming stack
since early 2004, as Maciej found out [1]:
Having actually dug speculatively I can see that the psABI was changed in
GCC 3.5 with commit e5e10fb4a350 ("re PR target/14539 (128-bit long double
improperly aligned)") back in Mar 2004, when the stack pointer alignment
was increased from 8 bytes to 16 bytes, and arch/alpha/kernel/entry.S has
various suspicious stack pointer adjustments, starting with SP_OFF which
is not a whole multiple of 16.
Also, as Magnus noted, "ALPHA Calling Standard" [2] required the same:
D.3.1 Stack Alignment
This standard requires that stacks be octaword aligned at the time a
new procedure is invoked.
However:
- the "normal" kernel stack is always misaligned by 8 bytes, thanks to
the odd number of 64-bit words in 'struct pt_regs', which is the very
first thing pushed onto the kernel thread stack;
- syscall, fault, interrupt etc. handlers may, or may not, receive aligned
stack depending on numerous factors.
Somehow we got away with it until recently, when we ended up with
a stack corruption in kernel/smp.c:smp_call_function_single() due to
its use of 32-byte aligned local data and the compiler doing clever
things allocating it on the stack.
This adds padding between the PAL-saved and kernel-saved registers
so that 'struct pt_regs' have an even number of 64-bit words.
This makes the stack properly aligned for most of the kernel
code, except two handlers which need special threatment.
Note: struct pt_regs doesn't belong in uapi/asm; this should be fixed,
but let's put this off until later.

Fix several issues in partition probing:
- The bailout for a bad partoffset must use put_dev_sector(), since the
preceding read_part_sector() succeeded.
- If the partition table claims a silly sector size like 0xfff bytes
(which results in partition table entries straddling sector boundaries),
bail out instead of accessing out-of-bounds memory.
- We must not assume that the partition table contains proper NUL
termination - use strnlen() and strncmp() instead of strlen() and
strcmp().

This driver supports page faults on PCI RID since commit <9f831c16c69e>
("iommu/vt-d: Remove the pasid present check in prq_event_thread") by
allowing the reporting of page faults with the pasid_present field cleared
to the upper layer for further handling. The fundamental assumption here
is that the detach or replace operations act as a fence for page faults.
This implies that all pending page faults associated with a specific RID
or PASID are flushed when a domain is detached or replaced from a device
RID or PASID.
However, the intel_iommu_drain_pasid_prq() helper does not correctly
handle faults for RID. This leads to faults potentially remaining pending
in the iommu hardware queue even after the domain is detached, thereby
violating the aforementioned assumption.
Fix this issue by extending intel_iommu_drain_pasid_prq() to cover faults
for RID.
Fixes: 9f831c16c69e ("iommu/vt-d: Remove the pasid present check in prq_event_thread")

With recent kernel, AMDGPU failed to resume after suspend on certain laptop.
Sample log:
-----------
Nov 14 11:52:19 Thinkbook kernel: iommu ivhd0: AMD-Vi: Event logged [ILLEGAL_DEV_TABLE_ENTRY device=0000:06:00.0 pasid=0x00000 address=0x135300000 flags=0x0080]
Nov 14 11:52:19 Thinkbook kernel: AMD-Vi: DTE[0]: 7d90000000000003
Nov 14 11:52:19 Thinkbook kernel: AMD-Vi: DTE[1]: 0000100103fc0009
Nov 14 11:52:19 Thinkbook kernel: AMD-Vi: DTE[2]: 2000000117840013
Nov 14 11:52:19 Thinkbook kernel: AMD-Vi: DTE[3]: 0000000000000000
This is because in resume path, CNTRL[EPHEn] is not set. Fix this by
setting CNTRL[EPHEn] to 1 in resume path if EFR[EPHSUP] is set.
Note
May be better approach is to save the control register in suspend path
and restore it in resume path instead of trying to set indivisual
bits. We will have separate patch for that.

Pull bcachefs fixes from Kent Overstreet:
"Just small stuff.
As a general announcement, on disk format is now frozen in my master
branch - future on disk format changes will be optional, not required.
- More fixes for going read-only: the previous fix was insufficient,
but with more work on ordering journal reclaim flushing (and a
btree node accounting fix so we don't split until we have to) the
tiering_replication test now consistently goes read-only in less
than a second.
- fix for fsck when we have reflink pointers to missing indirect
extents
- some transaction restart handling fixes from Alan; the "Pass
_orig_restart_count to trans_was_restarted" likely fixes some rare
undefined behaviour heisenbugs"

Fix a deadlock in pse_pi_get_current_limit and pse_pi_set_current_limit

The gpiochip_get_ngpios() uses chip_*() macros to print messages.
However these macros rely on gpiodev to be initialised and set,
which is not the case when called via bgpio_init(). In such a case
the printing messages will crash on NULL pointer dereference.
Replace chip_*() macros by the respective dev_*() ones to avoid
such crash.

This isn't generally necessary, but conditions have been observed where
SQE data is accessed from the original SQE after prep has been done and
outside of the initial issue. Opcode prep handlers must ensure that any
SQE related data is stable beyond the prep phase, but uring_cmd is a bit
special in how it handles the SQE which makes it susceptible to reading
stale data. If the application has reused the SQE before the original
completes, then that can lead to data corruption.
Down the line we can relax this again once uring_cmd has been sanitized
a bit, and avoid unnecessarily copying the SQE.
Fixes: 5eff57fa9f3a ("io_uring/uring_cmd: defer SQE copying until it's needed")

Now when we use scx_bpf_task_cgroup() in ops.tick() to get the cgroup of
the current task, the following error will occur:
scx_foo[3795244] triggered exit kind 1024:
runtime error (called on a task not being operated on)
The reason is that we are using SCX_CALL_OP() instead of SCX_CALL_OP_TASK()
when calling ops.tick(), which triggers the error during the subsequent
scx_kf_allowed_on_arg_tasks() check.
SCX_CALL_OP_TASK() was first introduced in commit 36454023f50b ("sched_ext:
Track tasks that are subjects of the in-flight SCX operation") to ensure
task's rq lock is held when accessing task's sched_group. Since ops.tick()
is marked as SCX_KF_TERMINAL and task_tick_scx() is protected by the rq
lock, we can use SCX_CALL_OP_TASK() to avoid the above issue. Similarly,
the same changes should be made for ops.disable() and ops.exit_task(), as
they are also protected by task_rq_lock() and it's safe to access the
task's task_group.

Now BPF only supports bpf_list_push_{front,back}_impl kfunc, not bpf_list_
push_{front,back}.
This patch fix this issue. Without this patch, if we use bpf_list kfunc
in scx, the BPF verifier would complain:
libbpf: extern (func ksym) 'bpf_list_push_back': not found in kernel or
module BTFs
libbpf: failed to load object 'scx_foo'
libbpf: failed to load BPF skeleton 'scx_foo': -EINVAL

Like other drivers qeth is calling local_bh_enable() after napi_schedule()
to kick-start softirqs [0].
Since netif_napi_add_tx() and napi_enable() now take the netdev_lock()
