sh: Couple kernel and user write page perm bits for CONFIG_X2TLB
pte_write() should check whether the permissions include either the user or kernel write permission bits. Likewise, pte_wrprotect() needs to remove both the kernel and user write bits. Without this patch handle_tlbmiss() doesn't handle faulting in pages from the P3 area (our vmalloc space) because of a write. Mappings of the P3 space have the _PAGE_EXT_KERN_WRITE bit but not _PAGE_EXT_USER_WRITE. Signed-off-by: Matt Fleming <matt@console-pimps.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
