Global signal cleanup, take 4

From: Richard Weinberger
Date: Mon Jul 21 2014 - 10:17:34 EST

This is v4 of the global signal cleanup series.

This patch series moves all remaining archs to the get_signal(), signal_setup_done()
and sigsp() functions. Currently these archs use open coded
variants of the said functions. Further, unused parameters get removed
from get_signal_to_deliver(), tracehook_signal_handler() and signal_delivered().

The following archs got zero build testing:
c6x, cris-v32, score, unicore, sh64.

The whole series can also be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/rw/misc.git signal_v4

Andrew, can you please pickup this series?

Changes since v3:
- Rebased to v3.16-rc6
- Fixed arm64 build (v3 contained an old patch :-( )
- Added more acks (parisc, avr32, c6x)

Changes since v2:
- Added ack to arc bits
- Dropped "metag: Use get_signal() signal_setup_done()", merged via metag tree
- Dropped signal translation helper, this will be addressed in another series

Changes since v1:
- Dropped "h8300: Use get_signal() signal_setup_done()", architecture got ripped out
- Dropped "openrisc: Use get_signal() signal_setup_done()", merged via openrisc tree
- Added ack to "c6x: Use get_signal() signal_setup_done()"
- Added ack to "hexagon: Use get_signal() signal_setup_done()"
- Added ack to "score: Use get_signal() signal_setup_done()"
- Added a common helper to translate signals
- Fixed some build issues
- Addressed comments
