Ricardo Koller 0dd8d22a88 KVM: selftests: aarch64: Relax userfaultfd read vs. write checks ... Only Stage1 Page table walks (S1PTW) writing a PTE on an unmapped page should result in a userfaultfd write. However, the userfaultfd tests in page_fault_test wrongly assert that any S1PTW is a PTE write. Fix this by relaxing the read vs. write checks in all userfaultfd handlers. Note that this is also an attempt to focus less on KVM (and userfaultfd) behavior, and more on architectural behavior. Also note that after commit 406504c7b0 ("KVM: arm64: Fix S1PTW handling on RO memslots"), the userfaultfd fault (S1PTW with AF on an unmaped PTE page) is actually a read: the translation fault that comes before the permission fault.
