Subject: [GIT PULL] Hexagon arch fixes
Hello Linus,
Please pull the following changes for the Hexagon architecture (and one
touching OpenRISC). They include various fixes to make use of additional
arch features and cleanups. The largest functional change is a cleanup
of the signal and event return paths.
Thanks,
Richard Kuo
