The ACRN Hypervisor did not support x2APIC and thus x2APIC support was
disabled by always returning false when VM checked for x2APIC support.
ACRN received full support of x2APIC and exports the capability through
CPUID feature bits.
Let VM decide if it needs to switch to x2APIC mode according to

Newer CAAM versions (Era 9+) support 16B IVs. Since for these devices
the HW limitation is no longer present newer version should process the

search_exception_tables() is an heavy operation, we have to avoid it.
When KUAP is selected, we'll know the fault has been blocked by KUAP.
Otherwise, it behaves just as if the address was already in the TLBs
and no fault was generated.

Exception fixup doesn't require the heady full regs saving,
do it from do_page_fault() directly.
For that, split bad_page_fault() in two parts.
As bad_page_fault() can also be called from other places than
handle_page_fault(), it will still perform exception fixup and
fallback on __bad_page_fault

I'm debugging a resume issue on one of our devices using the v5.4
kernel. The device has a PS/2 atkbd and a PS/2 touchpad. It looks like
PS/2 commands are getting intermingled with i8042 commands. This
results in our keyboard controller thinking it got some invalid data.
This usually happens 1 out

Newer CAAM versions (Era 9+) support 16B IVs. Since for these devices
the HW limitation is no longer present newer version should process the
requests containing 16B IVs directly in hardware without using a fallback.

This patch adds a selftest for MEMBARRIER_CMD_PRIVATE_RESTART_RSEQ_ON_CPU.
The test quite often fails without the previous patch in this patchset,
but consistently passes with it.

AFAICS there's not a single use of sd_flags.h that doesn't come with
its own SD_FLAG definition, so I suppose this should be:
#ifndef SD_FLAG
# error "Should not happen."
#endif
?

In the case of TPROXY, bind_conflict optimizations for SO_REUSEADDR or
SO_REUSEPORT are broken, possibly resulting in O(n) instead of O(1) bind
behaviour or in the incorrect reuse of a bind.
the kernel keeps track for each bind_bucket if all sockets in the
bind_bucket support SO_REUSEADDR or SO_RE
