Merge branch kvm-arm64/misc into kvmarm/next
* kvm-arm64/misc:
: Miscellaneous updates
:
: - Avoid trapping CTR_EL0 on systems with FEAT_EVT, as the register is
: commonly read by userspace
:
: - Make use of FEAT_BTI at hyp stage-1, setting the Guard Page bit to 1
: for executable mappings
:
: - Use a separate set of pointer authentication keys for the hypervisor
: when running in protected mode (i.e. pKVM)
:
: - Plug a few holes in timer initialization where KVM fails to free the
: timer IRQ(s)
KVM: arm64: Use different pointer authentication keys for pKVM
KVM: arm64: timers: Fix resource leaks in kvm_timer_hyp_init()
KVM: arm64: Use BTI for nvhe
KVM: arm64: Relax trapping of CTR_EL0 when FEAT_EVT is available
