Pull x86 fixes from Thomas Gleixner:
"A collection of assorted fixes:
- Fix for the pinned cr0/4 fallout which escaped all testing efforts
because the kvm-intel module was never loaded when the kernel was
compiled with CONFIG_PARAVIRT=n. The cr0/4 accessors are moved out
of line and static key is now solely used in the core code and
therefore can stay in the RO after init section. So the kvm-intel
and other modules do not longer reference the (read only) static
key which the module loader tried to update.
- Prevent an infinite loop in arch_stack_walk_user() by breaking out
of the loop once the return address is detected to be 0.
- Prevent the int3_emulate_call() selftest from corrupting the stack
when KASAN is enabled. KASASN clobbers more registers than covered
by the emulated call implementation. Convert the int3_magic()
selftest to a ASM function so the compiler cannot KASANify it.
- Unbreak the build with old GCC versions and with the Gold linker by
reverting the 'Move of _etext to the actual end of .text'. In both
cases the build fails with 'Invalid absolute R_X86_64_32S
relocation: _etext'
- Initialize the context lock for init_mm, which was never an issue
until the alternatives code started to use a temporary mm for
patching.
- Fix a build warning vs. the LOWMEM_PAGES constant where clang
complains rightfully about a signed integer overflow in the shift
operation by converting the operand to an ULL.
- Adjust the misnamed ENDPROC() of common_spurious in the 32bit entry
code"

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct virtio_scsi {
...
struct virtio_scsi_vq req_vqs[];
};
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.
So, replace the following form:
sizeof(*vscsi) + sizeof(vscsi->req_vqs[0]) * num_queues
with:
struct_size(vscsi, req_vqs, num_queues)
This code was detected with the help of Coccinelle.

[Why]
The drm_audio_component can be used to give pin ELD notifications
directly to the sound driver. This fixes audio endpoints disappearing
due to missing unsolicited notifications.
[How]
Send the notification via the audio component whenever we enable or
disable audio state on a stream. This matches what i915 does with
their drm_audio_component and what Takashi Iwai's proposed hack for
radeon/amdpgu did.
This is a bit delayed in when the notification actually occurs, however.
We wait until after all the programming is complete rather than sending
the notification mid sequence.
Particular care is needed for the get ELD callback since it can happen
outside the locking and fencing DRM does for atomic commits.

[Why]
In order to give pin notifications to the sound driver from DM we need
to know whether audio is enabled on a stream and what pin it's using
from DC.
[How]
Expose the instance via stream status if it's a mapped resource for
the stream. It will be -1 if there's no audio mapped.

Currently, the last stage boot loaders such as U-Boot can accept only
uImage which is an unnecessary additional step in automating boot
process.
Add an image header that boot loader understands and boot Linux from
flat Image directly.
This header is based on ARM64 boot image header and provides an
opportunity to combine both ARM64 & RISC-V image headers in future.
Also make sure that PE/COFF header can co-exist in the same image so
that EFI stub can be supported for RISC-V in future. EFI specification
needs PE/COFF image header in the beginning of the kernel image in order
to load it as an EFI application. In order to support EFI stub, code0
should be replaced with "MZ" magic string and res4(at offset 0x3c)
should point to the rest of the PE/COFF header (which will be added
during EFI support).

A dynamic formatting is issued whenever a write request returns with
either a No Record Found error (Command Mode), Incorrect Length error
(Transport Mode), or File Protected error (Transport Mode). All three
cases mean that the tracks in question haven't been initialized in a
desired format yet.
The part of the volume that was tried to be written on is then formatted
and the original request is re-queued.
As the formatting will happen during normal I/O operations, it is quite
likely that there won't be any memory available to build the respective
request. Another two pages of memory are allocated per volume
specifically for the dynamic formatting.
The dasd_eckd_build_format() function is extended to make sure that the
original startdev is reused. Also, all formatting and format check
functions use the new memory pool exclusively now to reduce complexity.
Read operations will always return zero data when unformatted areas are

The disk layout and volume information of a DASD reside in the first two
tracks of cylinder 0. When a DASD is set online, currently the first
three tracks are read and analysed to confirm an expected layout.
For CDL (Compatible Disk Layout) only count area data of the first track
is evaluated and checked against expected key and data lengths. For LDL
(Linux Disk Layout) the first and third track is evaluated. However,
an LDL formatted volume is expected to be in the same format across all
tracks. Checking the third track therefore doesn't have any more value
than checking any other track at random.
Now, an Extent Space Efficient (ESE) DASD is initialised by only
formatting the first two tracks, as those tracks always contain all
information necessarry.
Checking the third track on an ESE volume will therefore most likely
fail with a record not found error, as the third track will be empty.
This in turn leads to the device being recognised with a volume size of
0. Attempts to write volume information on the first two tracks then
fail with "no space left on device" errors.
Initialising the first three tracks for an ESE volume is not a viable
solution, because the third track is already a regular track and could
contain user data. With that there is potential for data corruption.
Instead, always only analyse the first two tracks, as it is sufficiant
for both CDL and LDL, and allow ESE volumes to be recognised as well.

There are structs that have never been used. There are also two function
prototypes which were forgotton in commit f9f8d02fae0d ("[S390] dasd:
revert LCU optimization").
Clean up and keep the header file tidy.

In preparation to enabling -Wimplicit-fallthrough, mark switch cases where
we are expecting to fall through.
This patch fixes the following warnings:
drivers/infiniband/sw/siw/siw_qp_rx.c: In function ‘siw_rdmap_complete’:
drivers/infiniband/sw/siw/siw_qp_rx.c:1214:18: warning: this statement may fall through [-Wimplicit-fallthrough=]
