Subject: [PATCH v2 24/28] target/ppc/mmu_common.c: Remove BookE handling from get_physical_address_wtlb()
Date: Thu, 02 May 2024 01:43:31 +0200 (CEST) [thread overview]
Message-ID: <cd05e33ea86d301cf64aa3925a6302b92249ee3c.1714606359.git.balaton@eik.bme.hu> (raw)
In-Reply-To: <cover.1714606359.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.
