Did you intend to leave your 2 "xxx - galak" comments in here?
Also, I think you have a problem - you allow CONFIG_SMP to be set
with CONFIG_FSL_BOOKE now, but if you actually turn on CONFIG_SMP, in
pgtable_32.c you're going to have build problems. CONFIG_SMP enables
hash_page_sync(), which we don't have on BookE. You need to add a !
BOOKE to the config protections in pgtable_32.c for hash_page_sync()
declaration and callers.
Cheers,
Becky
