Hi,
Here is a patch (used by perfmon2) that renames X86_FEATURE_DTES
to X86_FEATURE_DS to match Intel's documentation for the Debug Store
save area on i386. The patch also adds cpu_has_ds.
changelog:
- rename X86_FEATURE_DTES to X86_FEATURE_DS to match documentation
- adds cpu_has_ds to test for X86_FEATURE_DS
