Subject: x86 cpuid: enable clflush
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f2bcf4f01ce00f98cbbfe4320a919b431637e550;p=gem5.git

x86 cpuid: enable clflush
Note that clflush is only being enabled. It is not implemented
in actual. A warning is printed if the cpu encounters a clflush
instruction. We need to enable this instruction in cpuid since
JRE 1.7 tests for it.
