[Linux-ia64] kernel update (relative to v2.4.18)

[David Mosberger <davidm@napali.hpl.hp.com>]

The latest ia64 kernel patch is at
ftp://ftp.kernel.org/pub/linux/kernel/ports/ia64/v2.4/ in file:

        linux-2.4.18-ia64-020719.diff.gz

This patch has mostly bug-fixes for Itanium 2 machines and a few
additional drivers.  The problem reported by Alex, where the
McKinley-tuned memcpy() causes VGA console corruption has been worked
around by not using memcpy() at all for accessing the framebuffer
(this was arguably the wrong thing to do in the first place).
However, I do not fully understand yet what triggered this problem.
It would be good to make sure it's really not a bug in the new memcpy().
Ken, if you have a chance to look into it, I'd be interested to know
what you find.

I tried this kernel on the Intel Tiger platform, the hp Ski simulator,
and hp zx1 platform and it seems to work quite well.

Enjoy,
