logging of long delays at boot

Hi,

I wrote some crappy patch to log all long delays and sleeps during the boot process. It shows quite a few interesting calls to huge delays on my powerbook (where the kernel takes about 10 seconds to boot).

Well, I just post this here in case somebody is interested in it. This is _not_ a submission for merging with the mainline kernel.

The patch currently is prepared for powerpc only. Other architectures might need some adjustments in the arch code (some archs override msleep and stuff...)

Have fun.
