Pull the code to generalize the powerpc VIRQ_DEBUG code from Grant Likely. That code had been moved into generic irqdomain code, but still had powerpc-specific code and could only be enabled on powerpc. * 'irqdomain/merge' of git://git.secretlab.ca/git/linux-2.6: irqdomain/powerpc: updated defconfigs for VIRQ_DEBUG rename irqdomain: Remove powerpc dependency from debugfs file
