    Subject[PATCH 0/5] Rework of msrpm optimization and additional fixes for nested svm
    Date
    Hi,

    this is the updated version of the msrpm merge optimization in the nested vmrun
    path. With nested-shadow I see a performance improvement by a factor of two in
    an up guest with kernel compile times.
    A few other fixes are also included like the iopm check for nested io
    intercepts and the masking of lower 12 bits of the msrpm address supplied in
    the nested vmcb.
    Please review and/or apply these changes.

    Joerg
