Affects run-time (kernel) ACPICA, iASL, and acpi_help. The "SMBus
Control Method Interface Specification, Version 1.0, December 10,
1999" containes predefined names: _SBA _SBI _SBR _SBT _SBW. This was
done outside of the ACPI specification. This commit adds support for
ACPICA to recognize these named objects as predefined named objects.

Pull USB/PHY fixes from Greg KH:
"Here are some small USB and PHY driver fixes for 5.9-rc8
The PHY driver fix resolves an issue found by Dan Carpenter for a
memory leak.
The USB fixes fall into two groups:
- usb gadget fix from Bryan that is a fix for a previous security fix
that showed up in in-the-wild testing
- usb core driver matching bugfixes. This fixes a bug that has
plagued the both the usbip driver and syzbot testing tools this -rc
release cycle. All is now working properly so usbip connections
will work, and syzbot can get back to fuzzing USB drivers properly.
All have been in linux-next for a while with no reported issues"

memalloc_nocma_{save/restore} APIs can be used to skip page allocation
on CMA area, but, there is a missing case and the page on CMA area could
be allocated even if APIs are used. This patch handles this case to fix
the potential issue.
For now, these APIs are used to prevent long-term pinning on the CMA
page. When the long-term pinning is requested on the CMA page, it is
migrated to the non-CMA page before pinning. This non-CMA page is
allocated by using memalloc_nocma_{save/restore} APIs. If APIs doesn't
work as intended, the CMA page is allocated and it is pinned for a long
time. This long-term pin for the CMA page causes cma_alloc() failure
and it could result in wrong behaviour on the device driver who uses the
cma_alloc().
Missing case is an allocation from the pcplist. MIGRATE_MOVABLE pcplist
could have the pages on CMA area so we need to skip it if ALLOC_CMA
isn't specified.

The routine that applies debug flags to the kmem_cache slabs
inadvertantly prevents non-debug flags from being applied to those
same objects. That is, if slub_debug=<flag>,<slab> is specified,
non-debugged slabs will end up having flags of zero, and the slabs
may be unusable.
Fix this by including the input flags for non-matching slabs with the
contents of slub_debug, so that the caches are created as expected
alongside any debugging options that may be requested. With this, we
can remove the check for a NULL slub_debug_string, since it's covered
by the loop itself.
Fixes: e17f1dfba3 ("mm, slub: extend slub_debug syntax for multiple blocks")

The PFEC_MASK and PFEC_MATCH fields in the VMCS reverse the meaning of
the #PF intercept bit in the exception bitmap when they do not match.
This means that, if PFEC_MASK and/or PFEC_MATCH are set, the
hypervisor can get a vmexit for #PF exceptions even when the
corresponding bit is clear in the exception bitmap.
This is unexpected and is promptly detected by a WARN_ON_ONCE.
To fix it, reset PFEC_MASK and PFEC_MATCH when the #PF intercept
is disabled (as is common with enable_ept && !allow_smaller_maxphyaddr).
