KVM uses the current RIP as the NextRIP in vmcb02 to\nemulate a CPU without NRIPS.\n\nHowever, after L2 runs the first time, NextRIP will be updated by the CPU\nand/or KVM, and the current RIP is no longer the correct value to use in\nvmcb02.  Hence, after save/restore, use the current RIP if and only if a\nnested run is pending, otherwise use NextRIP.  Give soft_int_next_rip the\nsame treatment, as it's the same logic, just for a narrower use case.\n\n[sean: give soft_int_next_rip the same treatment]"
