    KVM: x86: Add code to track call origin for msr assignment · 8fe8ab46
    Will Auld authored
    In order to track who initiated the call (host or guest) to modify an msr
    value I have changed function call parameters along the call path. The
    specific change is to add a struct pointer parameter that points to (index,
    data, caller) information rather than having this information passed as
    individual parameters.
    The initial use for this capability is for updating the IA32_TSC_ADJUST msr
    while setting the tsc value. It is anticipated that this capability is
    useful for other tasks.
