Christophe Leroy 4f94b2c746 powerpc/8xx: Use L1 entry APG to handle _PAGE_ACCESSED for CONFIG_SWAP ... When CONFIG_SWAP is set, the TLB miss handlers have to also take into account _PAGE_ACCESSED flag. At the moment it is done by anding _PAGE_ACCESSED into _PAGE_PRESENT using 3 instructions. This patch uses APG for handling _PAGE_ACCESSED, allowing to just copy _PAGE_ACCESSED bit into APG field, hence reducing the action to a single instruction.
