Subject: powerpc: hash_page_sync should only be used on SMP & STD_MMU_32
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f4f3a1261ad70988ad45614ebc87e553143a332b;p=linux-beck.git

powerpc: hash_page_sync should only be used on SMP & STD_MMU_32

Clean up the ifdefs so we only use hash_page_sync if we have
CONFIG_SMP && CONFIG_PPC_STD_MMU_32.
