Subject: [PATCH for-6.2 38/43] target/arm: Use cpu_*_mmu instead of helper_*_mmu
Date: Wed, 28 Jul 2021 14:46:42 -1000	[thread overview]
Message-ID: <20210729004647.282017-39-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210729004647.282017-1-richard.henderson@linaro.org>

The helper_*_mmu functions were the only thing available
when this code was written.  This could have been adjusted
when we added cpu_*_mmuidx_ra, but now we can most easily
use the newest set of interfaces.
