svn commit: r265883 - head/sys/powerpc/ps3

[Nathan Whitehorn]

Author: nwhitehorn
Date: Sun May 11 16:49:31 2014
New Revision: 265883
URL: http://svnweb.freebsd.org/changeset/base/265883

Log:
  Fix interrupt allocation after changes to nexus. This makes PS3 boot
  multiuser again (this commit comes from the PS3 itself). Some problems
  still exist with SMP, apparently, as I had to boot a non-SMP kernel to
  get here.
