From: Tariq Saeed <tariq.x.saeed@xxxxxxxxxx> This patch has been added to the 3.18 stable tree. If you have any objections, please let us know. =============== [ Upstream commit 4f33f6c522948fffc345261896042b58dea23754 ] Commit be0c37c985eddc4 (MIPS: Rearrange PTE bits into fixed positions.) defines fixed PTE bits for MIPS R2. Then, commit d7b631419b3d230a4d383 (MIPS: pgtable-bits: Fix XPA damage to R6 definitions.) adds the MIPS R6 definitions in the same way as MIPS R2. But some R6 #ifdefs in the later commit are missing, so in this patch I fix that. Signed-off-by: Huacai Chen <chenhc@xxxxxxxxxx> Cc: Aurelien Jarno <aurelien@xxxxxxxxxxx> Cc: Steven J.
