Subject: [PATCH 0/8] PNP debugging rework

These patches add support for a boot-time switch to enable PNP debug
messages.  Currently, users have to recompile with CONFIG_PNP_DEBUG=y
to get PNP debug messages.

I copied the implementation strategy from Greg KH's USB patches:
    http://lkml.org/lkml/2008/8/8/529

These patches don't fix any bugs, and I know it's pretty late to
consider new stuff for 2.6.27.  The only reason to even consider them
is that 2.6.27 includes a significant PNP rewrite, and if 2.6.27 ends
up in a distro kernel, it will be much easier to work on problems if
users can collect debug information without rebuilding the kernel.
