[PATCH v2 0/7] linux-user: sigaction fixes/cleanups

[Richard Henderson]

Alpha had two bugs, one with the non-ka_restorer fallback
using the wrong offset, and the other with the ka_restorer
value getting lost in do_sigaction.

Sparc had another bug, where the ka_restorer field was
written to user memory.

Version 2 splits patch 2 into 6.
