This patchset, based on earlier work by Jeremy Fitzhardinge, implements paravirtual clock vsyscall support. It should be possible to implement Xen support relatively easily. It reduces clock_gettime from 500 cycles to 200 cycles on my testbox. Please review. >From my POV, this is ready to merge. v2: - Do not allow visibility of different <system_timestamp, tsc_timestamp> tuples. - Add option to disable vsyscall. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
