[Qemu-devel] [PATCH v3 14/34] target/arm: Simplify tlb_force_broadcast a


From: Richard Henderson
Subject: [Qemu-devel] [PATCH v3 14/34] target/arm: Simplify tlb_force_broadcast alternatives
Date: Sat, 3 Aug 2019 11:47:40 -0700

Rather than call to a separate function and re-compute any
parameters for the flush, simply use the correct flush
function directly.
