Subject: [PATCH v3 1/5] target/arm/kvm: Inline set_feature() calls
Date: Mon,  4 May 2020 19:24:44 +0200	[thread overview]
Message-ID: <20200504172448.9402-2-philmd@redhat.com> (raw)
In-Reply-To: <20200504172448.9402-1-philmd@redhat.com>

We want to move the inlined declarations of set_feature()
from cpu*.c to cpu.h. To avoid clashing with the KVM
declarations, inline the few KVM calls.

Suggested-by: Richard Henderson <richard.henderson@linaro.org>
