    KVM: PPC: Book3S: Add support for ibm,int-on/off RTAS calls · d19bd862
    Paul Mackerras authored
    This adds support for the ibm,int-on and ibm,int-off RTAS calls to the
    in-kernel XICS emulation and corrects the handling of the saved
    priority by the ibm,set-xive RTAS call.  With this, ibm,int-off sets
    the specified interrupt's priority in its saved_priority field and
    sets the priority to 0xff (the least favoured value).  ibm,int-on
    restores the saved_priority to the priority field, and ibm,set-xive
    sets both the priority and the saved_priority to the specified
    priority value.
