It's more than just review. I've expressed elsewhere that I'm not
convinced of the approach as a whole, complicating things further.
A re-work towards using ref-counting on the devices likely can't be
viewed as a re-submission (and hence likely won't qualify for 4.17
anymore at this point), but I think that's the only (long term)
viable path.

Well, obviously.

The replacement patch has gone in as 31b41ce858c8 ("x86/amd: only
call setup_force_cpu_cap for boot CPU").

Isn't this commit 755087eb9b10?

Afaict e83cd54611fe ("x86: Expose more MSR_ARCH_CAPS to hwdom").

19. [PATCH v2 00/12] x86: memcpy() / memset() (non-)ERMS flavors plus fallout
Status: Some parts committed, some parts entirely uncommented on.

20. [PATCH 0/2] x86/vMCE: address handling related adjustments
Status: Iirc no comments at all so far.

21: [PATCH v2 0/2] x86/mwait-idle: (remaining) SPR support
Status: Patch 1 still lacking an ack.

22: [PATCH v2 0/8] x86emul: a few small steps towards disintegration
Status: Iirc entirely ignored for about a year (since v1 submission).

23: [PATCH 00/11] x86: support AVX512-FP16
Status: v1 was reviewed, but some of the review comments need further
clarifying before I can sensibly make/submit v2.
Note: Depends on item 22 (albeit if absolutely necessary it could be
re-based ahead).

As per the XSA this isn't intended to be committed. If anything the
XSA may want re-issuing with this patch.

8. [PATCH v7 00/11] libs/guest: new CPUID/MSR interface
Status: Largely reviewed iirc, but there was something Andrew's input
was needed on, or he wasn't happy with.

9. [XEN PATCH 0/2] libxl: replace deprecated -sdl and -soundhw qemu options
Status: Patch 2 still having some discussion ongoing, i.e. as a
committer it's not clear to me whether the patch will want a minor
update.

v2 was a 3-patch series which has gone in already.

5. [PATCH 0/9] gnttab: further work from XSA-380 / -382 context
Status: Some parts are controversial, but this shouldn't prevent the
reviewing / progressing of non-controversial ones there (7-9).

6: [XEN PATCH v2 0/4] xen: rework compat headers generation
Status: The 3rd patch needs reviewing by someone speaking enough Perl.
