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) -----BEGIN PGP SIGNATURE----- iI0EABYKADUWIQSNXHjWXuzMZutrKNKivnWIJHzdFgUCaq7S2hccb2xpdmVyLnVw dG9uQGxpbnV4LmRldgAKCRCivnWIJHzdFuyFAPwMTw52duiQXiJd2MLUe7qndEWW s5vcAPDZIdDOWY4HewD/Xh7j5EwanNDM2DDXvdrgjnsTrwsJBW2ULIBKS6lvOA4= =fF21 -----END PGP SIGNATURE----- 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.
