[PATCH] ia64: use i386 dmi_scan.c
Enable DMI table parsing on ia64. 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. In addition, I reworked the DMI detection, such that on EFI-capable systems, it uses the efi.smbios pointer to find the table, rather than brute-force searching from 0xF0000. On non-EFI systems, it continues the brute-force search. My test system, an Intel S870BN4 'Tiger4', aka Dell PowerEdge 7250, with latest BIOS, does not list the IPMI controller in the ACPI namespace, nor does it have an ACPI SPMI table. Also note, currently shipping Dell x8xx EM64T servers don't have these either, so DMI is the only method for obtaining the address of the IPMI controller.
