Alan Cox: Linux 2.4.21pre3-ac5

Kernel.org
Mirrors

This patch fixes the random oops some people saw on 2.4.21pre-ac* before.
It should also fix highmem I/O and a pile of the minor glitches. I've left
the more interesting changes out of this patch set so that the stability
stuff can be dealt with first.

To minimise changes while verifying the fixes this is against pre3 still.
I'll move to pre4-ac1 next cut.
