From cd34e202faa4be7f77fd2f7a59824f13dc14901b Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Fri, 30 Mar 2012 19:42:26 +0900 Subject: [PATCH 1/2] sh: vsyscall: Fix up .eh_frame generation. Some improper formatting caused the .eh_frame generation to fail, resulting in gcc/g++ testsuite failures with regards to unwinding through the vDSO. Now that someone is actually working on this on the gcc side it's time to fix up the kernel side, too.
