What's become with PPC patches?

Hello.

    Since we were about to start working on LTTng in arch/powerpc/ tree (at
last), I've looked thru the current 2.6.18 patches, and was surprised in a bad
way about PPC patches which only looked like a shadow of what they were
several months ago, largely reminding the result of a failed rebase with only
some added lines and braces serving no particular purpose. Looks like that
disaster (I think it's the right word) happened after 2.6.17-lttng-0.5.108.
    Mattieau, could you clarify what happened? The patch has lost a lot of 
trace points (assmingly borrowed from my last year's LTT work), so it's going 
to be quite a setback for us, and completely unexpected... :-(

WBR, Sergei
