[PATCH 4.2.y-ckt 190/268] MIPS: Fix some missing CONFIG_CPU_MIPSR6 #ifdefs

From: Kamal Mostafa
Date: Wed Jan 27 2016 - 16:03:56 EST

4.2.8-ckt3 -stable review patch. If anyone has any objections, please let me know.


From: Huacai Chen <chenhc@xxxxxxxxxx>

commit 4f33f6c522948fffc345261896042b58dea23754 upstream.

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.
