Subject: [PATCH v2 05/17] cpu: Directly use get_paging_enabled() fallback handlers in place
Date: Mon, 1 Mar 2021 22:50:58 +0100 [thread overview]
Message-ID: <20210301215110.772346-6-f4bug@amsat.org> (raw)
In-Reply-To: <20210301215110.772346-1-f4bug@amsat.org>
No code uses CPUClass::get_paging_enabled() outside of hw/core/cpu.c:
$ git grep -F -- '->get_paging_enabled'
hw/core/cpu.c:74: return cc->get_paging_enabled(cpu);
hw/core/cpu.c:438: k->get_paging_enabled = cpu_common_get_paging_enabled;
target/i386/cpu.c:7418: cc->get_paging_enabled = x86_cpu_get_paging_enabled;
Check the handler presence in place and remove the common fallback code.
