Subject: asm-generic: add dummy pgprot_noncached()
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=0634a632f5dea8281ae7c9a96800582ff9eb1475;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git

asm-generic: add dummy pgprot_noncached()

Most architectures now provide a pgprot_noncached(), the
remaining ones can simply use an dummy default implementation,
except for cris and xtensa, which should override the
default appropriately.
