Subject: target/i386: Drop accel_uses_host_cpuid before x86_cpu_get_supported_cpuid
X-Git-Tag: v8.2.0-rc0~127^2~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=da472f94871e334ad8123d289df77f17d59f54f7;p=thirdparty%2Fqemu.git

target/i386: Drop accel_uses_host_cpuid before x86_cpu_get_supported_cpuid

x86_cpu_get_supported_cpuid() already checks for KVM/HVF
accelerators, so it is not needed to manually check it via
a call to accel_uses_host_cpuid() before calling it.
