-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.
