In order to integrate the system call header generation with generating
the asm-generic wrappers, restrict the generated headers to those that
actually exist in include/asm-generic/.
The path is already known, so add these as a dependency.
The asm-generic/bugs.h header was removed in commit 61235b24b9cb ("init:
Remove check_bugs() leftovers"), which now causes a build failure, so
drop it from the list.

The list of generated headers is rather outdated, some of these no longer
exist, while others are already listed in include/asm-generic/Kbuild
so there is no need to list them here.
As we start validating the list of headers against the files that exist,
the outdated ones now cause a warning.

If we start validating the existence of the asm-generic side of
generated headers, this one causes a warning:
make[3]: *** No rule to make target 'arch/um/include/generated/asm/bpf_perf_event.h', needed by 'all'. Stop.
The problem is that the asm-generic header only exists for the uapi
variant, but arch/um has no uapi headers and instead uses the x86
userspace API.
Add a custom file with an explicit redirect to avoid this.

The asm/gpio.h header is gone now that all architectures just use
gpiolib, and so the redirect is no longer valid.

This variable is set with the intention of being passed to the
subsequent strcmp() but something went wrong and it was left unused. Use
it now.

The way the delayed work is handled in ceph_monc_stop() is prone to
races with mon_fault() and possibly also finish_hunting(). Both of
these can requeue the delayed work which wouldn't be canceled by any of
the following code in case that happens after cancel_delayed_work_sync()
runs -- __close_session() doesn't mess with the delayed work in order
to avoid interfering with the hunting interval logic. This part was
missed in commit b5d91704f53e ("libceph: behave in mon_fault() if
cur_mon < 0") and use-after-free can still ensue on monc and objects
that hang off of it, with monc->auth and monc->monmap being
particularly susceptible to quickly being reused.
To fix this:
- clear monc->cur_mon and monc->hunting as part of closing the session
in ceph_monc_stop()
- bail from delayed_work() if monc->cur_mon is cleared, similar to how
it's done in mon_fault() and finish_hunting() (based on monc->hunting)
- call cancel_delayed_work_sync() after the session is closed

The commit 6533e558c650 ("i40e: Fix reset path while removing
the driver") introduced a new PF state "__I40E_IN_REMOVE" to block
modifying the XDP program while the driver is being removed.
Unfortunately, such a change is useful only if the ".ndo_bpf()"
callback was called out of the rmmod context because unloading the
existing XDP program is also a part of driver removing procedure.
In other words, from the rmmod context the driver is expected to
unload the XDP program without reporting any errors. Otherwise,
the kernel warning with callstack is printed out to dmesg.
Example failing scenario:
1. Load the i40e driver.
2. Load the XDP program.
3. Unload the i40e driver (using "rmmod" command).

Fix this by checking if the XDP program is being loaded or unloaded.

Also, move testing "__I40E_IN_REMOVE" flag to the beginning of XDP_SETUP

Adding support for G761 included adding support for an internal clock.
Enabling the internal clock requires setting a bit in the FAN_CMD2
register. This is implemented in g762_fan_init(). However, g762_fan_init()
is called before clock support is selected, and the flag indicating that
the internal clock should be used is not yet set.
Initialize the clock before initializing the fan to solve the problem.
While at it, also add "g7621" to the i2c_device_id array.

It's because hugetlb folio is passed to __folio_undo_large_rmappable()
unexpectedly. large_rmappable flag is imperceptibly set to hugetlb folio
since commit f6a8dd98a2ce ("hugetlb: convert alloc_buddy_hugetlb_folio to
use a folio"). Then commit be9581ea8c05 ("mm: fix crashes from deferred
split racing folio migration") makes folio_migrate_mapping() call
folio_undo_large_rmappable() triggering the bug. Fix this issue by
clearing large_rmappable flag for hugetlb folios. They don't need that
flag set anyway.

There is a potential race between __update_and_free_hugetlb_folio() and
try_memory_failure_hugetlb():
CPU1 CPU2

folio_test_hugetlb

-- Hugetlb flag is cleared but too late.
spin_unlock_irq(&hugetlb_lock);
When the above race occurs, raw error page info will be leaked. Even
worse, raw error pages won't have hwpoisoned flag set and hit
pcplists/buddy. Fix this issue by deferring
folio_clear_hugetlb_hwpoison() until __folio_clear_hugetlb() is done. So
all raw error pages will have hwpoisoned flag set.

The vmf->ptl in filemap_fault_recheck_pte_none() is still set from
handle_pte_fault(). But at the same time, we did a pte_unmap(vmf->pte).
After a pte_unmap(vmf->pte) unmap and rcu_read_unlock(), the page table
may be racily changed and vmf->ptl maybe fails to protect the actual page
table. Fix this by replacing pte_offset_map() with
pte_offset_map_nolock().
As David said, the PTL pointer might be stale so if we continue to use
it infilemap_fault_recheck_pte_none(), it might trigger UAF. Also, if
the PTL fails, the issue fixed by commit 58f327f2ce80 ("filemap: avoid
unnecessary major faults in filemap_fault()") might reappear.

get_current() always returns a valid address, this situation can happen
only during init stage and accessing .init.data from .text section during

function and they don't get inlined (remain in the .text section) while
the value returned by get_current() points into .init.data section.
Assuming get_current() always returns a valid address, this situation can
happen only during init stage and accessing .init.data from .text section
during that stage should pose no issues.

A few more Arm64 DeviceTree updates for v6.11
This introduces support for Lenovo Thinkpad Yoga slim 7x, LG Leon LTE,
and LG K10 (K420n).
In addition to this, all Gen-1 platforms gets the DWC3 quirk to disable
"SuperSpeed in park mode", which resolves an instabliity issue seen in
host mode.
For Fairphone 4, PM6150L and PMK8003 thermal sensors are added and
thermal zones defined.
Two fastrpc contexts on SM6350 are marked as non-secure, to allow
non-secure usage.
The video clock controller on SM8150 is introduced. IPQ9574 GCC is
marked as a interconnect provider. The vibrator block in the PM6150 is
described.
On SC7280 the download mode register is defined for SCM, allowing it to
enable/disable the ramdump support during a system crash.
Lastly, add a mailmap entry for Luca Weiss.

Commit 61df7b828204 ("lsm: fixup the inode xattr capability handling")
moved the responsibility of doing the inode xattr capability checking
out of the individual LSMs and into the LSM framework itself.
Unfortunately, while the original commit added the capability checks
to both the setxattr and removexattr code in the LSM framework, it
only removed the setxattr capability checks from the individual LSMs,
leaving duplicated removexattr capability checks in both the SELinux
and Smack code.
This patch removes the duplicated code from SELinux and Smack.

Like other SPI controller flags, bits_per_word_mask may be used by a
peripheral driver, so it needs to reflect the capabilities of the
underlying controller.

Adding spi_optimize_message() broke the spi-mux driver because it
calls spi_async() from it's transfer_one_message() callback. This
resulted in passing an incorrectly optimized message to the controller.
For example, if the underlying controller has an optimize_message()
callback, this would have not been called and can cause a crash when
the underlying controller driver tries to transfer the message.
Also, since the spi-mux driver swaps out the controller pointer by
replacing msg->spi, __spi_unoptimize_message() was being called with a
different controller than the one used in __spi_optimize_message(). This
could cause a crash when attempting to free the message resources when
__spi_unoptimize_message() is called in spi_finalize_current_message()
since it is being called with a controller that did not allocate the
resources.
This is fixed by adding a defer_optimize_message flag for controllers.
This flag causes all of the spi_[maybe_][un]optimize_message() calls to
be a no-op (other than attaching a pointer to the spi device to the
message).
This allows the spi-mux driver to pass an unmodified message to
spi_async() in spi_mux_transfer_one_message() after the spi device has
been swapped out. This causes __spi_optimize_message() and
__spi_unoptimize_message() to be called only once per message and with
the correct/same controller in each case.

Calling spi_maybe_unoptimize_message() in spi_async() is wrong because
the message is likely to be in the queue and not transferred yet. This
can corrupt the message while it is being used by the controller driver.
spi_maybe_unoptimize_message() is already called in the correct place
in spi_finalize_current_message() to balance the call to
spi_maybe_optimize_message() in spi_async().

Since commit c49cfa917025 ("USB: serial: use generic method if no
alternative is provided in usb serial layer"), USB serial core calls the
generic resume implementation when the driver has not provided one.
This can trigger a crash on resume with mos7840 since support for
multiple read URBs was added back in 2011. Specifically, both port read
URBs are now submitted on resume for open ports, but the context pointer
of the second URB is left set to the core rather than mos7840 port
structure.
Fix this by implementing dedicated suspend and resume functions for
mos7840.
Tested with Delock 87414 USB 2.0 to 4x serial adapter.
