From: Matt Fleming Date: Fri, 11 Dec 2009 22:58:17 +0000 (+0000) Subject: sh: Couple kernel and user write page perm bits for CONFIG_X2TLB X-Git-Tag: v2.6.33-rc1~63^2~20 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fcb4ebd678858850e8b029909064175cb627868d;p=pandora-kernel.git 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 Signed-off-by: Paul Mundt --- Reading git-diff-tree failed
