   4 Subject: [PATCH] AVR32: Fix sa_restorer when SA_ONSTACK is set
   5
   6 I don't remember exactly why we decided to pick the caller's value of
   7 sa_restorer when SA_ONSTACK is set, but it seems to break LTP's
   8 sigaltstack testcase. Some users have reported problems with
   9 sigaltstack as well; hopefully this will fix it.
