Merge tag 'kvmarm-fixes-7.3-1' of https://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/arm64 changes for 7.3, take #2
- Invalidate the ITS translation cache when the guest changes the
base address of the ITS tables (Fuad Tabba)
- Skip saving ITS devices with device IDs that are out-of-bounds
rather than failing the entire ITS save ioctl (Fuad Tabba)
- Close race between VM teardown and invalidations of nested MMUs
when handling MMU operations that are allowed to block
(Lorenzo Stoakes)
- Various fixes for the handling of the host's untrusted SVE
configuration in pKVM (Fuad Tabba)
- Make sure that empty SMCCC ranges based at 0 are rejected by the
kvm_smccc_set_filter() (Karl Mehltretter)
- Revoke the host mapping for pKVM's private stack pages, along
with a new sanity check that all mappings in the hyp's private
VA range have been correctly marked as hyp-owned (Fuad Tabba)
- Lifetime fixes for the array of shadow stage-2 MMUs, ensuring that
concurrent vCPU initialization cannot relocate in-use MMUs. Defer
the freeing of shadow stage-2 MMUs to the point that no other users
(e.g. MMU notifier) could reference them (Marc Zyngier)
- Drop useless WARN when rejecting an unsupported ioctl for pKVM
(Fuad Tabba)
- Fix the steal_time selftest to install correctly-sized mappings for
non-4K hosts (Sebastian Ott)
- Correct mapping of fine-grained trap for GCSPOPX instruction
(Mark Brown)
- Fix KVM_BUG_ON() due to missing handling of DBGBXVR<n> from 32-bit
guests (Karl Mehltretter)
