[PATCH 0/8] linux-user/sparc64: Implement signals

[Richard Henderson]

We were re-using sparc32 signal handling for sparc64.
In the process, clean up the altstack handling in do_*_sigreturn.

Richard Henderson (8):
  linux-user: Split out target_restore_altstack
  linux-user: Use target_restore_altstack in all sigreturn
  linux-user: Pass CPUArchState to do_sigaltstack
  linux-user: Pass CPUArchState to target_restore_altstack
  linux-user/sparc64: Move sparc64 code out of sparc32 signal.c
  linux-user/sparc: Clean up init_thread
  linux-user/sparc64: Include TARGET_STACK_BIAS in get_sp_from_cpustate
