Now that there's a platform that can make good use of it, here's
a series that can prevent the hash MMU code being built for 64s
platforms that don't need it.
Thanks,
Nick
Nicholas Piggin (6):
powerpc: Remove unused FW_FEATURE_NATIVE references
powerpc: Rename PPC_NATIVE to PPC_HASH_MMU_NATIVE
powerpc/pseries: Stop selecting PPC_HASH_MMU_NATIVE
powerpc/64s: Make hash MMU code build configurable
powerpc/microwatt: select POWER9_CPU
powerpc/microwatt: Stop building the hash MMU code
