[PATCH 2.6.15 1/2] ia64: use i386 dmi_scan.c

From: Matt Domsch <Matt_Domsch_at_dell.com>
Date: 2006-01-05 09:16:27
Andi Kleen has a patch in his x86_64 tree which enables the use of
i386 dmi_scan.c on x86_64.  dmi_scan.c functions are being used by the
drivers/char/ipmi/ipmi_si_intf.c driver for autodetecting the ports or
memory spaces where the IPMI controllers may be found.

This patch adds equivalent changes for ia64 as to what is in the
x86_64 tree.

Tested on ia64 with 2.6.15, plus the 'dmi' patch from
ftp://ftp.firstfloor.org/pub/ak/x86_64/quilt which Andi has queued for
submission for 2.6.16, plus a patch to ipmi_si_intf.c which will
follow separately.
