Sean Christopherson 643d95aac5 Revert "x86/mm: Introduce lookup_address_in_mm()" ... Drop lookup_address_in_mm() now that KVM is providing it's own variant of lookup_address_in_pgd() that is safe for use with user addresses, e.g. guards against page tables being torn down. A variant that provides a non-init mm is inherently dangerous and flawed, as the only reason to use an mm other than init_mm is to walk a userspace mapping, and lookup_address_in_pgd() does not play nice with userspace mappings, e.g. doesn't disable IRQs to block TLB shootdowns and doesn't use READ_ONCE() to ensure an upper level entry isn't converted to a huge page between checking the PAGE_SIZE bit and grabbing the address of the next level down. This reverts commit 13c72c060f.
