Please pull a smattering of x86 changes, most of which have been sitting around
on-list for quite some time. There are still quite a few KUT x86 series that
want attention, but they are all quite large and exceeded what little review
time I have for KUT :-/
Note, the posted interrupt test fails due to KVM bugs, patches posted:

nVMX: Verify KVM actually loads the value in HOST_PAT into the PAT MSR (2024-06-11 06:41:23 -0700)
----------------------------------------------------------------
x86 fixes, cleanups, and new testcases:
- Add a testcase to verify that KVM doesn't inject a triple fault (or any
other "error") if a nested VM is run with an EP4TA pointing MMIO.
- Play nice with CR4.CET in test_vmxon_bad_cr()
- Force emulation when testing MSR_IA32_FLUSH_CMD to workaround an issue where
Skylake CPUs don't follow the architecturally defined behavior, and so that
the test doesn't break if/when new bits are supported by future CPUs.
- Rework the async #PF test to support IRQ-based page-ready notifications.
- Fix a variety of issues related to adaptive PEBS.
- Add several nested VMX tests for virtual interrupt delivery and posted
interrupts.
- Ensure PAT is loaded with the default value after the nVMX PAT tests
(failure to do so was causing tests to fail due to all memory being UC).
- Misc cleanups.
