Switching from ->priv_destructor to dellink() has an unexpected

callers, may still be able to read the port list.
Instead of checking the return value of each hsr_port_get_hsr(),
we can just move it to ->ndo_uninit() which is called after
device unregister and synchronize_net(), and we still have RTNL

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.

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)

[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.

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).
