linux-user: Handle BUS_ADRALN in host_signal_handler (2021-11-02 07:00:52
-0400)
----------------------------------------------------------------
- Split out host signal handing from accel/tcg/user-exec.c
to linux-user/host/arch/host-signal.h
- Replace TCGCPUOps.tlb_fill with TCGCPUOps.record_sigsegv for user-only
- Add TCGCPUOps.record_sigbus for user-only
- Remove a lot of target-specific cpu_loop handling for signals,
now accomplished with generic code.
----------------------------------------------------------------
