With any luck we'll sort out the issue, but given how many bugs get

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

komeda_component_get_old_state() technically can return a NULL

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.

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.

When the static_key is part of the module, and the module calls
static_key_inc/enable() from it's __init section *AND* has a
static_branch_*() user in that very same __init section, things go
wobbly.
If the static_key lives outside the module, jump_label_add_module()
would append this module's sites to the key and jump_label_update()
would take the static_key_linked() branch and all would be fine.
If all the sites are outside of __init, then everything will be fine
too.
However, when all is aligned just as described above,
jump_label_update() calls __jump_label_update(.init = false) and we'll
not update sites in __init text.

The purpose of io_uring_cancel_files() is to wait for all requests
matching ->files to go/be cancelled. We should first drop files of a
request in io_req_drop_files() and only then make it undiscoverable for
io_uring_cancel_files.
First drop, then delete from list. It's ok to leave req->id->files
dangling, because it's not dereferenced by cancellation code, only
compared against. It would potentially go to sleep and be awaken by
following in io_req_drop_files() wake_up().

For the first time a req punted to io-wq, we'll initialize io_wq_work's
list to be NULL, then insert req to io_wqe->work_list. If this req is not
inserted into tail of io_wqe->work_list, this req's io_wq_work list will
point to another req's io_wq_work. For splitted bio case, this req maybe
inserted to io_wqe->work_list repeatedly, once we insert it to tail of
io_wqe->work_list for the second time, now io_wq_work->list->next will be
invalid pointer, which then result in many strang error, panic, kernel
soft-lockup, rcu stall, etc.
In my vm, kernel doest not have commit cc29e1bf0d ("block: disable

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 48ea1e32c3 ("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 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"

Pull modules updates from Jessica Yu:
"Summary of modules changes for the 5.11 merge window:
- Fix a race condition between systemd/udev and the module loader.
The module loader was sending a uevent before the module was fully
initialized (i.e., before its init function has been called). This
means udev can start processing the module uevent before the module
has finished initializing, and some udev rules expect that the
module has initialized already upon receiving the uevent.
This resulted in some systemd mount units failing if udev processes
the event faster than the module can finish init. This is fixed by
delaying the uevent until after the module has called its init
routine.
- Make the linker array sections for kernel params and module version
attributes more robust by switching to use the alignment of the
type in question.
Namely, linker section arrays will be constructed using the
alignment required by the struct (using __alignof__()) as opposed
to a specific value such as sizeof(void *) or sizeof(long). This is
less likely to cause breakages should the size of the type ever
change (Johan Hovold)
- Fix module state inconsistency by setting it back to GOING when a
module fails to load and is on its way out (Miroslav Benes)
- Some comment and code cleanups (Sergey Shtylyov)"
