[PATCH v3 0/7] convert dynamic_debug to use jump labels

[Jason Baron <jbaron@akamai.com>]

Hi,

Since v2, I found that s390, sparc, and tile could end up with
link errors such as:

`.exit.text' referenced in section `__jump_table' of drivers/built-in.o: defined in discarded section `.exit.text' of drivers/built-in.o

This is due to the fact the '__jump_table' may reference text
in an __exit section which is discarded during build/link time.
Thus, the sparc, arm and tile patch have been added to address
this issue.

In addition, an 'allyesconfig' on arm did not build either due
to the usage of -O0 compiler flag. This has been removed in 
this patch: http://lkml.iu.edu/hypermail/linux/kernel/1606.3/01587.html

So this series depends on that patch to build properly on arm
(which I currently see being pulled into linux-next).

-v3:
 *added sparc, arm, tile patches for cross section references
 *re-based on (4c5ea0a locking/static_key: Fix concurrent static_key_slow_inc())

Thanks,

-Jason
