[Buildroot] [PATCH 1/2] uClibc: remove AVR32 patches for 0.9.29
Thomas Petazzoni
thomas.petazzoni at free-electrons.com
Sun May 15 20:00:15 UTC 2011
The 0.9.29 version of uClibc can no longer be selected on AVR32 since
December 2009 (b642f7eefbf8c7f0111d74528390de31aaacf203). Therefore,
those two patches are now completely useless.

-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.
