From 51806b545834e0902dd2d17d1f66c7a2d83422f3 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Mon, 21 Jun 2021 09:51:13 -0300 Subject: target/ppc: Introduce ppc_xlate Create one common dispatch for all of the ppc_*_xlate functions. Use ppc64_v3_radix to directly dispatch between ppc_radix64_xlate and ppc_hash64_xlate. Remove the separate *_handle_mmu_fault and *_get_phys_page_debug functions, using common code for ppc_cpu_tlb_fill and ppc_cpu_get_phys_page_debug.
