#     
#     Pull irq updates from Thomas Gleixner:
#      "This is the second attempt after the first one failed miserably and
#       got zapped to unblock the rest of the interrupt related patches.
#     
#       A treewide cleanup of interrupt descriptor (ab)use with all sorts of
#       racy accesses, inefficient and disfunctional code. The goal is to
#       remove the export of irq_to_desc() to prevent these things from
#       creeping up again"
