+Subject: [PATCH] AVR32: Fix sa_restorer when SA_ONSTACK is set
+
+I don't remember exactly why we decided to pick the caller's value of
+sa_restorer when SA_ONSTACK is set, but it seems to break LTP's
+sigaltstack testcase. Some users have reported problems with
+sigaltstack as well; hopefully this will fix it.
