Merge tag 'kvmarm-fixes-6.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/arm64 fixes for 6.10, take #1
- Large set of FP/SVE fixes for pKVM, addressing the fallout
from the per-CPU data rework and making sure that the host
is not involved in the FP/SVE switching any more
- Allow FEAT_BTI to be enabled with NV now that FEAT_PAUTH
is copletely supported
- Fix for the respective priorities of Failed PAC, Illegal
Execution state and Instruction Abort exceptions
- Fix the handling of AArch32 instruction traps failing their
condition code, which was broken by the introduction of
ESR_EL2.ISS2
- Allow vpcus running in AArch32 state to be restored in
System mode
- Fix AArch32 GPR restore that would lose the 64 bit state
under some conditions
