#     powerpc/mm: Fix linux page tables build with some configs
#     
#     For some configs the build fails with:
#     
#       arch/powerpc/mm/dump_linuxpagetables.c: In function 'populate_markers':
#       arch/powerpc/mm/dump_linuxpagetables.c:306:39: error: 'PKMAP_BASE' undeclared (first use in this function)
#       arch/powerpc/mm/dump_linuxpagetables.c:314:50: error: 'LAST_PKMAP' undeclared (first use in this function)
#     
#     These come from highmem.h, including that fixes the build.
