hwmon: (nct6775) add ROG STRIX B550-A/X570-I GAMING
ASUS ROG STRIX B550-A/X570-I GAMING boards have got an nct6775 chip, but
by default there's no use of it because of resource conflict with WMI
method.
This commit adds "ROG STRIX B550-A GAMING" and "ROG STRIX X570-I GAMING" to
the list of boards that can be monitored using ASUS WMI.

mm: delete unsafe BUG from page_cache_add_speculative()
It is not easily reproducible, but on 5.16-rc I have several times hit
the VM_BUG_ON_PAGE(PageTail(page), page) in
page_cache_add_speculative(): usually from filemap_get_read_batch() for
an ext4 read, yesterday from next_uptodate_page() from
filemap_map_pages() for a shmem fault.
That BUG used to be placed where page_ref_add_unless() had succeeded,
but now it is placed before folio_ref_add_unless() is attempted: that is
not safe, since it is only the acquired reference which makes the page
safe from racing THP collapse or split.
We could keep the BUG, checking PageTail only when
folio_ref_try_add_rcu() has succeeded; but I don't think it adds much
value - just delete it.

mm, hwpoison: fix condition in free hugetlb page path
When a memory error hits a tail page of a free hugepage,
__page_handle_poison() is expected to be called to isolate the error in
4kB unit, but it's not called due to the outdated if-condition in
memory_failure_hugetlb(). This loses the chance to isolate the error in
the finer unit, so it's not optimal. Drop the condition.
This "(p != head && TestSetPageHWPoison(head)" condition is based on the
old semantics of PageHWPoison on hugepage (where PG_hwpoison flag was
set on the subpage), so it's not necessray any more. By getting to set
PG_hwpoison on head page for hugepages, concurrent error events on
different subpages in a single hugepage can be prevented by
TestSetPageHWPoison(head) at the beginning of memory_failure_hugetlb().
So dropping the condition should not reopen the race window originally
mentioned in commit
b985194c8c0a ("hwpoison, hugetlb:
lock_page/unlock_page does not match for handling a free hugepage")

This comes from crashkernel= being parsed independent from the kernel

mm: mempolicy: fix THP allocations escaping mempolicy restrictions
alloc_pages_vma() may try to allocate THP page on the local NUMA node
first:
page = __alloc_pages_node(hpage_node,
gfp | __GFP_THISNODE | __GFP_NORETRY, order);
And if the allocation fails it retries allowing remote memory:
if (!page && (gfp & __GFP_DIRECT_RECLAIM))
page = __alloc_pages_node(hpage_node,
gfp, order);
However, this retry allocation completely ignores memory policy nodemask
allowing allocation to escape restrictions.
The first appearance of this bug seems to be the commit
ac5b2c18911f
("mm: thp: relax __GFP_THISNODE for MADV_HUGEPAGE mappings").
The bug disappeared later in the commit
89c83fb539f9 ("mm, thp:
consolidate THP gfp handling into alloc_hugepage_direct_gfpmask") and
reappeared again in slightly different form in the commit
76e654cc91bb
("mm, page_alloc: allow hugepage fallback to remote nodes when
madvised")
Fix this by passing correct nodemask to the __alloc_pages() call.

platform/x86/intel: Remove X86_PLATFORM_DRIVERS_INTEL
While introduction of this menu brings a nice view in the configuration tools,
it brought more issues than solves, i.e. it prevents to locate files in the
intel/ subfolder without touching non-related Kconfig dependencies elsewhere.
Drop X86_PLATFORM_DRIVERS_INTEL altogether.
Note, on x86 it's enabled by default and it's quite unlikely anybody wants to
disable all of the modules in this submenu.

When waking up from s3 suspend the Coef 0x10 is set to 0x0220 instead of
0x0020 on the ALC256 codec. Setting the value manually makes the sound
