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.
