Merge tag 'kvmarm-fixes-5.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/arm64 fixes for Linux 5.8, take #1
* 32bit VM fixes:
- Fix embarassing mapping issue between AArch32 CSSELR and AArch64
ACTLR
- Add ACTLR2 support for AArch32
- Get rid of the useless ACTLR_EL1 save/restore
- Fix CP14/15 accesses for AArch32 guests on BE hosts
- Ensure that we don't loose any state when injecting a 32bit
exception when running on a VHE host
* 64bit VM fixes:
- Fix PtrAuth host saving happening in preemptible contexts
- Optimize PtrAuth lazy enable
- Drop vcpu to cpu context pointer
- Fix sparse warnings for HYP per-CPU accesses
