Paolo,
Here's a first set of fixes, most of which has been simmering in -next
for some time now. The most important one is a series from Oliver,
plugging a (hard to trigger) race that would result in the wrong
mapping being established at S2.
The rest is a bunch of cleanups and HW workarounds (the usual Apple
vgic issue that keeps cropping up on new SoCs).
Please pull,
M.

Merge branch kvm-arm64/pgtable-fixes-6.4 into kvmarm-master/fixes (2023-05-11 15:26:01 +0100)
----------------------------------------------------------------
KVM/arm64 fixes for 6.4, take #1
- Plug a race in the stage-2 mapping code where the IPA and the PA
would end up being out of sync
- Make better use of the bitmap API (bitmap_zero, bitmap_zalloc...)
- FP/SVE/SME documentation update, in the hope that this field
becomes clearer...
- Add workaround for the usual Apple SEIS brokenness
- Random comment fixes
