2017-10-20s390x/tcg: flush the tlb on SIGP SET PREFIXDavid Hildenbrand

2017-10-20s390x/tcg: implement STOP and RESET interrupts for TCGDavid Hildenbrand
Implement them like KVM implements/handles them. Both can only be triggered via SIGP instructions. RESET has (almost) the lowest priority if the CPU is running, and the highest if the CPU is STOPPED. This is handled in SIGP code already. On delivery, we only have to care about the "CPU running" scenario. STOP is defined to be delivered after all other interrupts have been delivered. Therefore it has the actual lowest priority. As both can wake up a CPU if sleeping, indicate them correctly to external code (e.g. cpu_has_work()).

2017-10-20s390x/tcg: handle WAIT PSWs during interrupt injectionDavid Hildenbrand
If we encounter a WAIT PSW, we have to halt immediately. Using cpu_loop_exit() at this point feels wrong. Simply leaving cs->exception_index set doesn't result in an immediate stop. This is also necessary to properly handle SIGP STOP interrupts later.

2017-10-20s390x/tcg: turn INTERRUPT_EXT into a maskDavid Hildenbrand
External interrupts are currently all handled like floating external interrupts, they are queued. Let's prepare for a split of floating and local interrupts by turning INTERRUPT_EXT into a mask. While we can have various floating external interrupts of one kind, there is usually only one (or a fixed number) of the local external interrupts. So turn INTERRUPT_EXT into a mask and properly indicate the kind of external interrupt. Floating interrupts will have to moved out of one CPU instance later once we have SMP support. The only floating external interrupts used right now are SERVICE interrupts, so let's use that name. Following patches will clean up SERVICE interrupt injection. This get's rid of the ugly special handling for cpu timer and clock comparator interrupts. And we really only store the parameters as defined by the PoP.
