Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull kvm fixes from Paolo Bonzini:
"ARM:
- Fix EL2 Stage-1 MMIO mappings where a random address was used
- Fix SMCCC function number comparison when the SVE hint is set
RISC-V:
- Fix KVM_GET_REG_LIST API for ISA_EXT registers
- Fix reading ISA_EXT register of a missing extension
- Fix ISA_EXT register handling in get-reg-list test
- Fix filtering of AIA registers in get-reg-list test
x86:
- Fixes for TSC_AUX virtualization
- Stop zapping page tables asynchronously, since we don't zap them as
often as before"
