Bump the ZO_z_extra_bytes margin for zstd.
Zstd needs 3 bytes per 128 KB, and has a 22 byte fixed overhead.
Zstd needs to maintain 128 KB of space at all times, since that is

For now, that's arch/x86/boot/compressed/vmlinux.bin.zst but probably more

* Add unzstd() and the zstd decompress interface.

The decompress_method() and unzstd() functions are used to decompress

* Remove a double definition of the CHECK_F macro when the zstd

Now the calls to enable/disable a thermal zone are centralized in a
call to a function, we can add in these the corresponding netlink

Thank Jon for the feedback,
The kbuild bot recently added the W=1 option, which triggered
documentation cleanups to squelch hundreds of kernel-doc warnings.
To make sure new kernel contributions don't add regressions to
kernel-doc descriptors, this patch suggests an option to treat
warnings as

The number of slots and slot areas can be unsigned int, since on 64-bit,
the maximum amount of memory is 2^52, the minimum alignment is 2^21, so
the slot number cannot be greater than 2^31. The slot areas are limited
by MAX_SLOT_AREA, currently 100. Replace the type used for slot number,
which is
Drop the warning on seeing "--" in handle_mem_options. This will trigger
whenever one of the memory options is present in the command line
together with "--", but there's no problem if that is the case.
Replace goto with break.

Commit
f28442497b5c ("x86/boot: Fix KASLR and memmap= collision")
converted mem_vector type to use 64-bit on the 32-bit kernel as well,
based on Thomas's review [0]. However:
- the code still doesn't consistently use 64-bit types. For instance,
mem_avoid_overlap uses 32-bit types when checking
On 64-bit, the kernel must be placed below MAXMEM (64TiB with 4-level
paging or 4PiB with 5-level paging). This is currently not enforced by
KASLR, which thus implicitly relies on physical memory being limited to
less than 64TiB.
On 32-bit, the limit is KERNEL_IMAGE_SIZE (512MiB). This is
Handle the possibility that the command line is NULL.
Replace open-coded strlen with a function call.

Get rid of unnecessary temporary variables and redundant tests in
__process_mem_region.
Fix one minor bug: in case of an overlap, the beginning of the region
should be used even if it is exactly image_size, not just strictly
larger.
Change type of minimum/image_size arguments in
Short-circuit the whole function on 32-bit.
Replace the loop to determine the number of 1Gb pages with arithmetic.
Fix one minor bug: if the end of the region is aligned on a 1Gb
boundary, the current code will not use the last available 1Gb page due
to an off-by-one error.

The first 7 patches are cleanup and minor bugfixes on the x86 KASLR
code.
The last one is a bit of an RFC. The memory regions used for KASLR are
stored as 64-bit even on a 32-bit kernel. However there are still a few
local variables that are 32-bit, but should be ok as far as I can see
because

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1].

Bios now updated to latest. Same kernel panic issue. Log below.
I think it is related to power cycling quickly.
Should APIC work if PC power cycled in a few seconds or is that the problem?

Hi,
This is a macro pseudo-keyword, which expands to /* fallthrough */
for compilers that don't support the attribute __fallthrough__. See:

213 #if __has_attribute(__fallthrough__)
