Subject[patch] Fixes to make x86-64 arch compile
Hi!

This patch is needed to make 2.5 compile on x86-64. It also fixes a
bunch of warnings, where drivers stuff pointers into ints or vice versa.

You can pull the cset from:
bk://kernel.bkbits.net/vojtech/x86-64


ChangeSet@1.975, 2003-02-06 15:50:20+01:00, vojtech@suse.cz
x86-64: Minor fixes to make the kernel compile and remove warnings.
