#     powerpc/64s/radix: Fix build failure with RADIX_MMU=n
#     
#     After merging the powerpc tree, today's linux-next build (powerpc64
#     allnoconfig) failed like this:
#     
#      arch/powerpc/mm/book3s64/pgtable.c:216:3:
#      error: implicit declaration of function 'radix__flush_all_lpid_guest'
#     
#     radix__flush_all_lpid_guest() is only declared for
#     CONFIG_PPC_RADIX_MMU which is not set for this build.
#     
#     Fix it by adding an empty version for the RADIX_MMU=n case, which
#     should never be called.
#     
#     Fixes: 99161de3a283 ("powerpc/64s/radix: tidy up TLB flushing code")
