The name of the "load_address" objects has been modified, but the
corresponding entry in the gitignore file must be updated.
Update the load_address entry in the gitignore file to account for

__fatal_error routine doesn't check strerror_r() return value,
which results in the following compile time warning:
posix_timers.c: In function ‘__fatal_error’:
posix_timers.c:31:9: warning: ignoring return value of ‘strerror_r’ declared with attribute ‘warn_unused_result’ [-Wunused-result]
31 | strerror_r(errno, buf, sizeof(buf));
Fix this by adding a check for return value and error handling appropriate
for the GNU-specific strerror_r() in use in __fatal_error(). Check if
return string is null and handle accordingly.
From Linux strerror_r() manual page:
"The GNU-specific strerror_r() returns a pointer to a string containing
the error message. This may be either a pointer to a string that the
function stores in buf, or a pointer to some (immutable) static string
(in which case buf is unused). If the function stores a string in buf,
then at most buflen bytes are stored (the string may be truncated if
buflen is too small and errnum is unknown). The string always includes
a terminating null byte."

For intel_wakeref_t, opaque is reasonable, but disguising the underlying
struct ref_tracker * as an unsigned long is not so great. Update the
typedef to remove one level of disguise.
Although the kernel coding style strongly discourages pointer typedefs,
it's a better alternative, and an incremental improvement on the status
quo. It provides much better type safety than an unsigned long could,
and prevents passing magic -1 instead of INTEL_WAKEREF_DEF. Moreover, it
provides a gradual path for replacing intel_wakeref_t with struct
ref_tracker * if desired.
As an extra safety measure, check for error pointers in
intel_ref_tracker_free() before passing them on to ref_tracker_free(),
to catch any mistakes with mock gt special wakeref value.

Use explicit casts to convert between intel_wakeref_t and unsigned long,
to not rely on intel_wakeref_t underlying type remaining unsigned long,
allowing us to change it as needed. (And yes, this is indeed preparation
for changing the typedef for intel_wakeref_t.)

Add a dedicated macro for the special mock gt wakeref value, with a cast
to intel_wakeref_t, instead of assuming you can assign or compare the
wakeref to -ENODEV directly.
Arguably the whole thing is a hack that should not exist, but at least
make it slightly less hacky.
Side note: If this value were to ever end up in
intel_ref_tracker_free(), it would wreak havoc.

CONFIG_DRM_I915_USERFAULT_AUTOSUSPEND is an int, defaulting to 250. When
the wakeref is non-zero, it's either -1 or a dynamically allocated
pointer, depending on CONFIG_DRM_I915_DEBUG_RUNTIME_PM. It's likely that
the code works by coincidence with the bitwise AND, but with
CONFIG_DRM_I915_DEBUG_RUNTIME_PM=y, there's the off chance that the
condition evaluates to false, and intel_wakeref_auto() doesn't get
called. Switch to the intended logical AND.

If the recv returns zero, or an error, then it doesn't matter if more
data has already been received for this buffer. A condition like that
should terminate the multishot receive. Rather than pass in the
collected return value, pass in whether to terminate or keep the recv
going separately.
Note that this isn't a bug right now, as the only way to get there is
via setting MSG_WAITALL with multishot receive. And if an application
does that, then -EINVAL is returned anyway. But it seems like an easy
bug to introduce, so let's make it a bit more explicit.

Without this fix, error injection into CXL 2.0 root ports through the

Since commit f79dc03fe68c ("kconfig: refactor choice value calculation"),
Kconfig for ARCH=powerpc may result in an infinite loop. This occurs
because there are two entries for POWERPC64_CPU in a choice block.
If the same symbol appears twice in a choice block, the ->choice_link
node is added twice to ->choice_members, resulting a corrupted linked
list.
A simple test case is:
choice
prompt "choice"
config A
bool "A"
config B
bool "B 1"
config B
bool "B 2"
endchoice
Running 'make defconfig' results in an infinite loop.
One solution is to replace the current two entries:
config POWERPC64_CPU
bool "Generic (POWER5 and PowerPC 970 and above)"
depends on PPC_BOOK3S_64 && !CPU_LITTLE_ENDIAN
select PPC_64S_HASH_MMU
config POWERPC64_CPU
bool "Generic (POWER8 and above)"
depends on PPC_BOOK3S_64 && CPU_LITTLE_ENDIAN
select ARCH_HAS_FAST_MULTIPLIER
select PPC_64S_HASH_MMU
select PPC_HAS_LBARX_LHARX
with the following single entry:
config POWERPC64_CPU
bool "Generic 64 bit powerpc"
depends on PPC_BOOK3S_64
select ARCH_HAS_FAST_MULTIPLIER if CPU_LITTLE_ENDIAN
select PPC_64S_HASH_MMU
select PPC_HAS_LBARX_LHARX if CPU_LITTLE_ENDIAN
In my opinion, the latter looks cleaner, but PowerPC maintainers may
prefer to display different prompts depending on CPU_LITTLE_ENDIAN.
For now, this commit fixes the issue in Kconfig, restoring the original
behavior. I will reconsider whether such a use case is worth supporting.

Commit aab94339cd85 ("of: Add support for linking device tree blobs
into vmlinux") introduced a mechanism to embed DTBs into vmlinux.
Initially, it was used for wrapping boot DTBs in arch/*/boot/dts/, but
it is now reused for more generic purposes, such as testing.
Built-in DTBs are discarded because KERNEL_DTB() is part of INIT_DATA,
as defined in include/asm-generic/vmlinux.lds.h.
This has not been an issue so far because OF unittests are triggered
during boot, as defined by late_initcall(of_unittest).
However, the recent clk KUnit test additions have caused problems
because KUnit can execute test suites after boot.
For example:
# echo > /sys/kernel/debug/kunit/clk_register_clk_parent_data_device/run
This command triggers a stack trace because built-in DTBs have already
been freed.
While it is possible to move such test suites from kunit_test_suites to
kunit_test_init_section_suites, it would be preferable to avoid usage
limitations.
This commit moves non-boot built-in DTBs to the .rodata section. Since
these generic DTBs are looked up by name, they do not need to be placed
in the special .dtb.init.rodata section.
Boot DTBs should remain in .dtb.init.rodata because the arch boot code
generally does not know the DT name, thus it uses the __dtb_start symbol
to locate it.
This separation also ensures that the __dtb_start symbol references the
boot DTB. Currently, the .dtb.init.rodata is a mixture of both boot and
non-boot DTBs. The __dtb_start symbol must be followed by the boot DTB,
but we currently rely on the link order (i.e., the order in Makefiles),
which is very fragile.
The implementation is kind of cheesy; the section is .dtb.init.rodata
when $(obj) starts with arch/$(SRCARCH)/boot/dts, and .rodata section
otherwise. This will be refactored later.

For gettimeofday, -ffixed-r30 was passed to work around a bug in Go
code, where the vDSO trampoline forgot to save and restore this register
across function calls. But Go requires a different trampoline for every
call, and there's no reason that new Go code needs to be broken and add
more bugs. So remove -ffixed-r30 for getrandom.

"assigned" and "assigned->name" are allocated in snd_mixer_oss_proc_write()
using kmalloc() and kstrdup(), so there is no point in using kfree_const()
to free these resources.
Switch to the more standard kfree() to free these resources.
This could avoid a memory leak.

Currently, if alsa development package is not installed on the user's
system then the make command would print a `pagefull` of errors. In
particular one error message is repeated 3 times. This error is returned
by `pkg-config` and since it is not being handeled appropriately,
repeated calls to `pkg-config` prints the same message again.
This patch adds check for alsa package installation. If alsa is not
installed, a short and consize error is returned. Also, it does not
affect the compilation of other tests.

Retry the first read and write to downstream at least 10 times
with a 50ms delay if not hdcp2 capable(dock decides to stop advertising
hdcp2 capability for some reason). The reason being that
during suspend resume Dock usually keep the HDCP2 registers inaccesible
causing AUX error. This wouldn't be a big problem if the userspace
just kept retrying with some delay while it continues to play low
values content but most userpace applications end up throwing an error
when it receives one from KMD. This makes sure we give the dock
and the sink devices to complete its power cycle and then try HDCP
authentication.

fs/bcachefs/bkey.h:557:41: error:

The original commit only renamed the variable for little endian builds.
Rename it for big endian builds as well to fix the problem.

Cloning a descriptor table picks the size that would cover all currently
opened files. That's fine for clone() and unshare(), but for close_range()
there's an additional twist - we clone before we close, and it would be
a shame to have
close_range(3, ~0U, CLOSE_RANGE_UNSHARE)
leave us with a huge descriptor table when we are not going to keep
anything past stderr, just because some large file descriptor used to
be open before our call has taken it out.
Unfortunately, it had been dealt with in an inherently racy way -
sane_fdtable_size() gets a "don't copy anything past that" argument
(passed via unshare_fd() and dup_fd()), close_range() decides how much
should be trimmed and passes that to unshare_fd().
The problem is, a range that used to extend to the end of descriptor
table back when close_range() had looked at it might very well have stuff
grown after it by the time dup_fd() has allocated a new files_struct
and started to figure out the capacity of fdtable to be attached to that.
That leads to interesting pathological cases; at the very least it's a
QoI issue, since unshare(CLONE_FILES) is atomic in a sense that it takes
a snapshot of descriptor table one might have observed at some point.
Since CLOSE_RANGE_UNSHARE close_range() is supposed to be a combination
of unshare(CLONE_FILES) with plain close_range(), ending up with a
weird state that would never occur with unshare(2) is confusing, to put
it mildly.
It's not hard to get rid of - all it takes is passing both ends of the
range down to sane_fdtable_size(). There we are under ->files_lock,
so the race is trivially avoided.
So we do the following:
* switch close_files() from calling unshare_fd() to calling
dup_fd().
* undo the calling convention change done to unshare_fd() in
60997c3d45d9 "close_range: add CLOSE_RANGE_UNSHARE"
* introduce struct fd_range, pass a pointer to that to dup_fd()
and sane_fdtable_size() instead of "trim everything past that point"
they are currently getting. NULL means "we are not going to be punching
any holes"; NR_OPEN_MAX is gone.
* make sane_fdtable_size() use find_last_bit() instead of
open-coding it; it's easier to follow that way.
* while we are at it, have dup_fd() report errors by returning
ERR_PTR(), no need to use a separate int *errorp argument.

xol_add_vma() maps the uninitialized page allocated by __create_xol_area()
into userspace. On some architectures (x86) this memory is readable even
without VM_READ, VM_EXEC results in the same pgprot_t as VM_EXEC|VM_READ,
although this doesn't really matter, debugger can read this memory anyway.
