target-ppc: Disentangle pte_check()
Currently support for both 32-bit and 64-bit hash MMUs share an implementation of pte_check. But there are enough differences that this means the shared function has several very ugly conditionals on "is_64b". This patch cleans things up by separating out the 64-bit version (putting it into mmu-hash64.c) and the 32-bit hash version (putting it in mmu-hash32.c). Another copy remains in mmu_helper.c, which is used for the 6xx software loaded TLB paths. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>
