Subject: [RFC PATCH v2 3/8] target/arm: Directly use arm_cpu_has_work instead of CPUClass::has_work
Date: Thu,  4 Mar 2021 23:23:18 +0100
Message-ID: <20210304222323.1954755-4-f4bug@amsat.org> (raw)
In-Reply-To: <20210304222323.1954755-1-f4bug@amsat.org>

There is only one CPUClass::has_work() ARM handler: arm_cpu_has_work().

Avoid a dereference by declaring it in "internals.h" and call it
directly  in the WFI helper.
