Hi Paul,
In my experience, dcbz slows down the hot-cache case because it adds a
few cycles to the execution time of the inner loop, and on most 64-bit
PowerPC implementations, it doesn't actually help even in the
cold-cache case because the store queue does enough write combining

Hi Adrian and Arnd,
After all, it won't matter whether we'll unify resp. remove

That wasn't my idea. The logic was that if one more file exists

we get 22 more files to remove without anyone having to look

For some reason long ago I decided that we should zero out the time base
when we calibrate the decrementer. The problem is that this can be
harmful in SMP systems where the firmware has already synchronized the
time bases on the various cores.

We need either all architectures changed or none at all - we do need the
arch headers to become more similar, not more different.
And this is why we need an agreement _before_ an asm-generic header gets
added, not after it.
We already have the agreement..
