Subject: [PATCH v3 25/33] target/ppc/mmu_common.c: Remove BookE handling from get_physical_address_wtlb()
Date: Wed, 08 May 2024 02:15:18 +0200 (CEST)	[thread overview]
Message-ID: <31a3baf4f598b8ebd0108180c3f5e26ebfbaff64.1715125376.git.balaton@eik.bme.hu> (raw)
In-Reply-To: <cover.1715125376.git.balaton@eik.bme.hu>

This function is no longer called for BookE MMU model so remove parts
related to it. This has uncovered a few may be used uninitialised
warnings that are also fixed.
