Subject: [PATCH 06/16] cpu: Directly use get_memory_mapping() fallback handlers in place
Date: Fri, 26 Feb 2021 17:32:17 +0100 [thread overview]
Message-ID: <20210226163227.4097950-7-f4bug@amsat.org> (raw)
In-Reply-To: <20210226163227.4097950-1-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.
