    Subject[PATCH v2 0/6] KVM: optimize memslots searching
    This is the more work base on my v1 patchset which is posted some months ago,
    it can be found at:

    Change log:
    - sort memslots base on its size and do the line search instead of binary
    search base on gfn, it is from Avi's idea.
    - in order to reduce cache footprint, memslots are sorted in the array of
    kvm->memslots->memslots[] and introduce a table to map slot id to index in
    the array

    There is the performance result:

    autotest for RHEL.6.1 setup/boot/reboot/shutdown(average):
    ept=1: before: 449.5 after: 447.8
    ept=0: before: 532.7 after: 529.8

    ept=1: before: 127.94 after: 126.98
    ept=0: before: 196.85 after: 189.66
