This series introduces a common API for performing range-based TLB invalidation. This is then used to supplant kvm_arch_flush_remote_tlbs_memslot() and pave the way for two other patch series: 1. https://lore.kernel.org/kvm/20230109215347.3119271-1-rananta@xxxxxxxxxx/ Adds ARM support for range-based TLB invalidation and needs a mechanism to invoke it from common code. This series provides such a mechanism via kvm_arch_flush_remote_tlbs_range(). 2. https://lore.kernel.org/kvm/20221208193857.4090582-1-dmatlack@xxxxxxxxxx/ Refactors the TDP MMU into common code, which requires an API for range-based TLB invaliation. This series is based on patches 29-33 from (2.), but I made some further cleanups after looking at it a second time. Tested on x86_64 and ARM64 using KVM selftests.
