Hi all,
After merging the powerpc tree, today's linux-next build (powerpc64
allnoconfig) failed like this:
arch/powerpc/mm/built-in.o: In function `.hash__early_init_mmu':
(.init.text+0x7d8): undefined reference to `.hpte_init_native'
Caused by commit
166dd7d3fbf2 ("powerpc/64: Move MMU backend selection out of platform code")
hpte_init_native is in hash_native_64 which is only built for
CONFIG_PPC_NATIVE. I added the following fix patch (which is probably
not correct).
