Subject: [PULL 17/31] cpu: Directly use get_memory_mapping() fallback handlers in place
Date: Wed, 26 May 2021 16:46:56 -0700 [thread overview]
Message-ID: <20210526234710.125396-18-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210526234710.125396-1-richard.henderson@linaro.org>
From: Philippe Mathieu-Daudé <f4bug@amsat.org>
No code uses CPUClass::get_memory_mapping() outside of hw/core/cpu.c:
$ git grep -F -- '->get_memory_mapping'
hw/core/cpu.c:87: cc->get_memory_mapping(cpu, list, errp);
hw/core/cpu.c:439: k->get_memory_mapping = cpu_common_get_memory_mapping;
target/i386/cpu.c:7422: cc->get_memory_mapping = x86_cpu_get_memory_mapping;
Check the handler presence in place and remove the common fallback code.
