[PATCH] powerpc/mm: Eliminate not possible mmu features at compile time

Depending on the CONFIG selected, many of the MMU features are not possible. Lets only get the possible ones in MMU_FTRS_POSSIBLE. This allows gcc to get rid at compile time of code related to not possible features. Signed-off-by: Christophe Leroy --- arch/powerpc/include/asm/mmu.h | 31 +++
