Looks better.

Grant - what's the plan about that CONFIG_VIRQ_DEBUG thing? In theory
something like it could be useful as a generic thing, but at least
right now it is clearly powerpc-specific (not just that the config
option only exists for powerpc: it has that whole
'powerpc_debugfs_root' thing in it)?

Stephen's patch very much looks like the right thing, but if there was
some plan to actually make this generic ...
