Subject: [PATCH v4 11/33] target/ppc/mmu_common.c: Move some debug logging
Date: Thu, 09 May 2024 01:36:14 +0200 (CEST)	[thread overview]
Message-ID: <5a82816a6aa18887e48f9d0b788f99f55277a980.1715209155.git.balaton@eik.bme.hu> (raw)
In-Reply-To: <cover.1715209155.git.balaton@eik.bme.hu>

Move the debug logging within ppc6xx_tlb_check() from after its only
call to simplify the caller.
