powerpc/mm: Fix definitions of FORCE_MAX_ZONEORDER in Kconfig (066c4b87) · Commits · 戴 / test

The current definitions set ranges and defaults for 32 and 64-bit only using "PPC_STD_MMU" which means hash based MMU. This uselessly restrict the usefulness for the upcoming 64-bit BookE port, but more than that, it's broken on 32-bit since the only 32-bit platform supporting multiple page sizes currently is 44x which does -not- have PPC_STD_MMU_32 set. This fixes it by using PPC64 and PPC32 instead. Signed-off-by:
