New PAGG patch for 2.6.10, build fix

I just uploaded a new PAGG patch for 2.6.10.

When we updated pagg_attach to have a return value, I neglected to fix up
the pagg_attach macro used when CONFIG_PAGG isn't set.  The end result
was, if you had the PAGG patch in place but didn't configure PAGG on for
your kernel, you would get a build failure.  This is now fixed.

I also updated the pagg hook init function pointer comments per our
earlier discussion.

Find the 'linux-2.6.10-pagg.patch-4' patch at the PAGG web site.
