[qemu-s390x] [PATCH v2 for-2.12 00/16] s390x/tcg: cleanup and fix program interrupts |

I have quite some patches on my queue for 2.12. (booting Fedora 26/27
guests, floating interrupts, machine checks, missing instructions ...)
So let's start slowly This series gets rid of program_interrupt() and
potential_page_fault(). We now always properly restore the cpu state when
injecting/delivering a program interrupt. So there is no need to update
the state via potential_page_fault() anymore.
In addition, handling for program interrupts comming via
s390_cpu_virt_mem_rw() was missing something for the TCG case. Also fixed.
v1 -> v2:
- renamed program_interrupt_ra() to s390_program_interrupt()
- introduce and use RA_IGNORED for KVM.
- switch to cpu_exit_loop_restore() and don't check if ra is set
- "s390x: handle exceptions during s390_cpu_virt_mem_rw() correctly (TCG)"
-> split out "s390x/tcg: don't exit the cpu loop in s390_cpu_virt_mem_rw()"
- "s390x/tcg: use program_interrupt_ra() in SCLP Service Call"
-> moved qemu_mutex_lock_iothread(); further up
- "s390x/tcg: drop program_interrupt()"
-> move restore to tcg_s390_program_interrupt() via cpu_loop_exit_restore()
- smaller requested cleanups
David Hildenbrand (16):
s390x/tcg: introduce and use s390_program_interrupt()
s390x/tcg: get rid of runtime_exception()
s390x/tcg: rip out dead tpi code
s390x/ioinst: pass the retaddr to all IO instructions
s390x/pci: pass the retaddr to all PCI instructions
s390x/diag: pass the retaddr into handle_diag_308()
s390x: handle exceptions during s390_cpu_virt_mem_rw() correctly (TCG)
s390x/tcg: don't exit the cpu loop in s390_cpu_virt_mem_rw()
s390x/tcg: io instructions don't need potential_page_fault()
s390x/tcg: use s390_program_interrupt() in SCLP Service Call
s390x/tcg: use s390_program_interrupt() in DIAG
s390x/tcg: use s390_program_interrupt() in per_check_exception()
s390x/tcg: use s390_program_interrupt() in SACF
s390x/tcg: use s390_program_interrupt() in STSI
s390x/tcg: drop program_interrupt()
s390x/tcg: drop potential_page_fault()
