Merge branch kvm-arm64/aarch32-idreg-trap into kvmarm-master/next
* kvm-arm64/aarch32-idreg-trap:
: .
: Add trapping/sanitising infrastructure for AArch32 systen registers,
: allowing more control over what we actually expose (such as the PMU).
:
: Patches courtesy of Oliver and Alexandru.
: .
KVM: arm64: Fix new instances of 32bit ESRs
KVM: arm64: Hide AArch32 PMU registers when not available
KVM: arm64: Start trapping ID registers for 32 bit guests
KVM: arm64: Plumb cp10 ID traps through the AArch64 sysreg handler
KVM: arm64: Wire up CP15 feature registers to their AArch64 equivalents
KVM: arm64: Don't write to Rt unless sys_reg emulation succeeds
KVM: arm64: Return a bool from emulate_cp()
