From a754f7f34e9c74adf65a0149c5e2382077a6e594 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Fri, 16 Jul 2021 17:49:09 -0700 Subject: [PATCH] accel/tcg: Expand ATOMIC_MMU_LOOKUP_* Unify the parameters of atomic_mmu_lookup between cputlb.c and user-exec.c. Call the function directly, and remove the macros.
