ARM: 7829/1: Add ".text.unlikely" and ".text.hot" to arm unwind tables
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>
