KVM: PPC: Book3S: Add support for ibm,int-on/off RTAS calls
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.
