    SubjectBasic perf PMU support for Haswell v1
    Date
    This is based on v7 of the full Haswell PMU support, but 
    ported to the latest perf/core and stripped down to the "basic support"
    as requested.

    I decided to include LBRs in the basic support. These are 4 patches
    self contained at the end, so could be also handled as a separate
    unit if that is preferable.

    Contains support for:
    - Basic Haswell PMU and PEBS support
    - Late unmasking of the PMI
    - Support for wide counters
    - New TSX counter flags, exported as sysfs attributes
    - Support for checkpointed counters.
    - New LBR flags, exported as new flags with tools support

    Available from
    git://git.kernel.org/pub/scm/linux/kernel/git/ak/linux-misc hsw/pmu4-basics

    For more details on the Haswell PMU please see the SDM. For more details on TSX
    please see http://halobates.de/adding-lock-elision-to-linux.pdf
