Subject: KVM: x86: rename EMULATE_DO_MMIO
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ac0a48c39af31fe27bdb1afca7b26f109ff1c704;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

KVM: x86: rename EMULATE_DO_MMIO

The next patch will reuse it for other userspace exits than MMIO,
namely debug events.
