commit 849b882b52df0f276d9ffded01d85654aa0da422 upstream. It appears that gcc may put some code in ".text.unlikely" or ".text.hot" sections. Right now those aren't accounted for in unwind tables. Add them. I found some docs about this at: http://gcc.gnu.org/onlinedocs/gcc-4.6.2/gcc.pdf Without this, if you have slub_debug turned on, you can get messages that look like this: unwind: Index not found 7f008c50 Signed-off-by: Doug Anderson <dianders@chromium.org> Acked-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> [wangkai: backport to 3.10 - adjust context ] Signed-off-by: Wang Kai <morgan.wang@huawei.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |
