2014-01-31gcc: Include patch scheduled for GCC 4.8.3 to fix epilogue on ARMHolger Hans Peter Freyther
GCC 4.8.0, 4.8.1 and 4.8.2 can generate broken epilogues for the ABI used by the kernel. Apply the patch that is included for GCC 4.8.3 from http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58854. The issue was found on Yocto/Dora and the patch should be backported to this branch. A kernel built with Dora's GCC 4.8.1 misbehaved on: while true; do (for i in `seq 1 100`; do echo "Log message... $RANDOM"; done) | logger; done busybox's syslogd would from time to read a huge negative value and then exit, strace would get stuck waiting on a syscall. After this patch it appears to work better. Signed-off-by: Holger Hans Peter Freyther <holger@moiji-mobile.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
