Subject: [PATCH v5 06/18] target/s390x: Handle tec in s390_cpu_tlb_fill
Date: Tue, 1 Oct 2019 10:16:02 -0700 [thread overview]
Message-ID: <20191001171614.8405-7-richard.henderson@linaro.org> (raw)
In-Reply-To: <20191001171614.8405-1-richard.henderson@linaro.org>
As a step toward moving all excption handling out of mmu_translate,
copy handling of the LowCore tec value from trigger_access_exception
into s390_cpu_tlb_fill. So far this new plumbing isn't used.
