Hi Paolo,
Here's a bunch of fixes that cropped up during the merge window,
mostly falling into two categories: 32bit system register accesses,
and 64bit pointer authentication handling.
Please pull,
M.
The following changes since commit 8f7f4fe756bd5cfef73cf8234445081385bdbf7d:

----------------------------------------------------------------
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
----------------------------------------------------------------
