The following patches clean up various issues with the signal and return path parts of the Hexagon arch port, which were pointed out by Al Viro: https://lkml.org/lkml/2012/2/11/128 The work pending check was moved into a C routine to make it more readable and to make sure we repeat the check when necessary. Also, various arguments and return values for signal handling should now be fixed. The patches can also be viewed in the context of my next batch of cleanups at my repo: git://git.kernel.org/pub/scm/linux/kernel/git/rkuo/linux-hexagon-kernel.git Any feedback is appreciated.
