target-ppc: Move SLB handling into a mmu-hash64.c As a first step to disentangling the handling for 64-bit hash MMUs from the rest, we move the code handling the Segment Lookaside Buffer (SLB) (which only exists on 64-bit hash MMUs) into a new mmu-hash64.c file.

target-ppc: Disentangle get_physical_address() paths Depending on the MSR state, for 64-bit hash MMUs, get_physical_address can either call check_physical (which has further tests for mmu type) or get_segment64. Similarly for 32-bit hash MMUs we can either call check_physucal or get_bat() and get_segment32(). This patch splits off the whole get_physical_addresss() path for hash MMUs into 32-bit and 64-bit versions, handling real mode correctly for such MMUs without going to check_physical and rechecking the mmu type. Correspondingly, the hash MMU specific paths in check_physical() are removed. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>

target-ppc: Disentangle hash mmu paths for cpu_ppc_handle_mmu_fault cpu_ppc_handle_mmu_fault() calls get_physical_address() (whose behaviour depends on MMU type) then, if that fails, issues an appropriate exception - which again has a number of dependencies on MMU type. This patch starts converting cpu_ppc_handle_mmu_fault() to have a single switch on MMU type, calling MMU specific fault handler functions which deal with both translation and exception delivery appropriately for the MMU type. We convert 32-bit and 64-bit hash MMUs to this new model, but the existing code is left in place for other MMU types for now.
