Catalin Marinas 73e86cb03c arm64: Move PTE_RDONLY bit handling out of set_pte_at() ... Currently PTE_RDONLY is treated as a hardware only bit and not handled by the pte_mkwrite(), pte_wrprotect() or the user PAGE_* definitions. The set_pte_at() function is responsible for setting this bit based on the write permission or dirty state. This patch moves the PTE_RDONLY handling out of set_pte_at into the pte_mkwrite()/pte_wrprotect() functions. The PAGE_* definitions to need to be updated to explicitly include PTE_RDONLY when !PTE_WRITE. The patch also removes the redundant PAGE_COPY(_EXEC) definitions as they are identical to the corresponding PAGE_READONLY(_EXEC).
