Nicolas Pitre 2ce9804fbd [ARM] 3030/2: fix permission check in the obscur cmpxchg syscall ... Patch from Nicolas Pitre Quoting RMK: |pte_write() just says that the page _may_ be writable. It doesn't say |that the MMU is programmed to allow writes. If pte_dirty() doesn't |return true, that means that the page is _not_ writable from userspace. |If you write to it from kernel mode (without using put_user) you'll |bypass the MMU read-only protection and may end up writing to a page |owned by two separate processes.
