The fast kernel headers tree

Kernel developer Ingo Molnar has been quiet for a while; now we know why.He has just announced a massiveset of patches (touching over half of the files in the kernel tree)reworking how header files are handled.

The fast-headers tree offers a +50-80% improvement in absolutekernel build performance on supported architectures, depending onthe config. This is a major step forward in terms of Linux kernelbuild efficiency & performance.

A justified question would be: why on Earth 2,200 commits??

It seems likely that interesting conversations will follow; stay tuned.
