There is one issue in here: one of my test configurations

the .text.init alignment patch.
With any luck we'll sort out the issue, but given how many bugs get
fixed all over the place and how unrelated those features seem my
guess is that we're just running into something that's been lurking
for a while and has already been fixed in the newer QEMU (though I
wouldn't be surprised if it's one of these implicit assumptions we
have in the boot flow). If it was hardware I'd be strongly inclined to

KASAN found this problem. find_first_bit() expects to look at a
pointer pointing to a long, but we look at a u32 - this is going to be
an issue with endianness but, KSAN already flags this as out-of-bounds
stack reads. This fixes it by just importing inot a local long.

komeda_component_get_old_state() technically can return a NULL
pointer. komeda_compiz_set_input() even warns when this happens, but
then proceeeds to use that NULL pointer to compare memory content there
agains the new state to see if it changed. In this case, it's better to
assume that the input changed as there is no old state to compare
against and thus assume the changes happen anyway.

There are a few places that call round{up|down}_pow_of_two() with the
value zero, and this causes undefined behavior warnings. Avoid
calling those macros if such a nonsense value is passed; it's a minor
optimization as well, as we handle it as either an error or a value to
be skipped, instead.

The PCM hw_params core function tries to clear up the PCM buffer
before actually using for avoiding the information leak from the
previous usages or the usage before a new allocation. It performs the
memset() with runtime->dma_bytes, but this might still leave some
remaining bytes untouched; namely, the PCM buffer size is aligned in
page size for mmap, hence runtime->dma_bytes doesn't necessarily cover
all PCM buffer pages, and the remaining bytes are exposed via mmap.
This patch changes the memory clearance to cover the all buffer pages
if the stream is supposed to be mmap-ready (that guarantees that the
buffer size is aligned in page size).

Currently the standard memory allocator (snd_dma_malloc_pages*())
passes the byte size to allocate as is. Most of the backends
allocates real pages, hence the actual allocations are aligned in page
size. However, the genalloc doesn't seem assuring the size alignment,
hence it may result in the access outside the buffer when the whole
memory pages are exposed via mmap.
For avoiding such inconsistencies, this patch makes the allocation
size always to be aligned in page size.
Note that, after this change, snd_dma_buffer.bytes field contains the
aligned size, not the originally requested size. This value is also
used for releasing the pages in return.

Since commit d4cfb30fce03 ("ALSA: pcm: Set per-card upper limit of PCM
buffer allocations") snd_pcm_lib_preallocate_dma_free() is a single line
function that has one caller, which is another single line function.
Clean this up a bit and remove snd_pcm_lib_preallocate_dma_free() and
directly call do_free_pages() from snd_pcm_lib_preallocate_free(). This is
a bit less boilerplate.

When inserting a VMA, we restrict the placement to the low 4G unless the
caller opts into using the full range. This was done to allow usersapce
the opportunity to transition slowly from a 32b address space, and to
avoid breaking inherent 32b assumptions of some commands.
However, for insert we limited ourselves to 4G-4K, but on verification
we allowed the full 4G. This causes some attempts to bind a new buffer
to sporadically fail with -ENOSPC, but at other times be bound
successfully.
commit 48ea1e32c39d ("drm/i915/gen9: Set PIN_ZONE_4G end to 4GB - 1
page") suggests that there is a genuine problem with stateless addressing
that cannot utilize the last page in 4G and so we purposefully excluded
it. This means that the quick pin pass may cause us to utilize a buggy
placement.

Pull GPIO updates from Linus Walleij:
"This is the bulk of the GPIO changes for the v5.11 kernel cycle:
Core changes:
- Retired the old set-up function for GPIO IRQ chips. All chips now
use the template struct gpio_irq_chip and pass that to the core to
be set up alongside the gpio_chip. We can finally get rid of the
old cruft.
- Some refactoring and clean up of the core code.
- Support edge event timestamps to be stamped using REALTIME (wall
clock) timestamps. We have found solid use cases for this, so we
support it.
New drivers:
- MStar MSC313 GPIO driver.
- HiSilicon GPIO driver.
Driver improvements:
- The PCA953x driver now also supports the NXP PCAL9554B/C chips.
- The mockup driver can now be probed from the device tree which is
pretty useful for virtual prototyping of devices.
- The Rcar driver now supports .get_multiple()
- The MXC driver dropped some legacy and became a pure device tree
client.
- The Exar driver was moved over to the IDA interface for
enumerating, and also switched over to using regmap for register
access"

Pull cifs updates from Steve French:
"The largest part are for support of the newer mount API which has been
needed for cifs/smb3 mounts for a long time due to the new API's
better handling of remount, and better error reporting. There are
three additional small cleanup patches for this being tested, that are
not included yet.
This series also includes addition of support for the SMB3 witness
protocol which can provide important notifications from the server to
client on server address or export or network changes. This can be
useful for example in order to be notified before the failure - when a
server's IP address changes (in the future it will allow us to support
server notifications of when a share is moved).
It also includes three patches for stable e.g. some that better handle
some confusing error messages during session establishment"

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing updates from Steven Rostedt:
"The major update to this release is that there's a new arch config
option called CONFIG_HAVE_DYNAMIC_FTRACE_WITH_ARGS.
Currently, only x86_64 enables it. All the ftrace callbacks now take a
struct ftrace_regs instead of a struct pt_regs. If the architecture
has HAVE_DYNAMIC_FTRACE_WITH_ARGS enabled, then the ftrace_regs will
have enough information to read the arguments of the function being
traced, as well as access to the stack pointer.
This way, if a user (like live kernel patching) only cares about the
arguments, then it can avoid using the heavier weight "regs" callback,
that puts in enough information in the struct ftrace_regs to simulate
a breakpoint exception (needed for kprobes).
A new config option that audits the timestamps of the ftrace ring
buffer at most every event recorded.
Ftrace recursion protection has been cleaned up to move the protection
to the callback itself (this saves on an extra function call for those
callbacks).
Perf now handles its own RCU protection and does not depend on ftrace
to do it for it (saving on that extra function call).
New debug option to add "recursed_functions" file to tracefs that
lists all the places that triggered the recursion protection of the
function tracer. This will show where things need to be fixed as
recursion slows down the function tracer.
The eval enum mapping updates done at boot up are now offloaded to a
work queue, as it caused a noticeable pause on slow embedded boards.
Various clean ups and last minute fixes"
