Subject: [PATCH v3 15/33] target/ppc/mmu_common.c: Inline and remove check_physical()
Date: Wed, 08 May 2024 02:15:08 +0200 (CEST) [thread overview]
Message-ID: <9ac7c9fa281582f9f5ddc42d15f0a49f466f07d6.1715125376.git.balaton@eik.bme.hu> (raw)
In-Reply-To: <cover.1715125376.git.balaton@eik.bme.hu>
This function just does two assignments and and unnecessary check that
is always true so inline it in the only caller left and remove it.
