#     powerpc: Make PPC_64K_PAGES depend on only 44x or PPC_BOOK3S_64
#     
#     In commit 7820856a4fcd ("powerpc/mm/book3e/64: Remove unsupported
#     64Kpage size from 64bit booke") we dropped the 64K page size support
#     from the 64-bit nohash (Book3E) code.
#     
#     But we didn't update the dependencies of the PPC_64K_PAGES option,
#     meaning a randconfig can still trigger this code and cause a build
#     breakage, eg:
#       arch/powerpc/include/asm/nohash/64/pgtable.h:14:2: error: #error "Page size not supported"
#       arch/powerpc/include/asm/nohash/mmu-book3e.h:275:2: error: #error Unsupported page size
#     
#     So remove PPC_BOOK3E_64 from the dependencies. This also means we
#     don't need to worry about PPC_FSL_BOOK3E, because that was just trying
#     to prevent the PPC_BOOK3E_64=y && PPC_FSL_BOOK3E=y case.
