[PATCH 11/24] target/ppc/mmu_common.c: Split off real mode cases in get_physical_address_wtlb() |
Date: |
Wed, 24 Apr 2024 00:31:22 +0200 (CEST) |
The real mode handling is identical in the remaining switch cases.
Split off these common real mode cases into a separate conditional to
leave only the else branches in the switch that are different.
