Subject: [PATCH v2 02/10] target/ppc: Use MMUAccessType with *_handle_mmu_fault
Date: Mon, 21 Jun 2021 09:51:07 -0300	[thread overview]
Message-ID: <20210621125115.67717-3-bruno.larsen@eldorado.org.br> (raw)
In-Reply-To: <20210621125115.67717-1-bruno.larsen@eldorado.org.br>

From: Richard Henderson <richard.henderson@linaro.org>

These changes were waiting until we didn't need to match
the function type of PowerPCCPUClass.handle_mmu_fault.
