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.

So rather than doing the pa->va->pa conversion, just keep physical addresses in struct efi. This fixes a DMI bug: the efi structure contained the physical SMBIOS address on x86 but the virtual address on ia64, so dmi_scan_machine() used ioremap() on a virtual address on ia64. This is essentially the same as an earlier patch by Matt Tolentino: http://marc.theaimsgroup.com/?l=linux-kernel&m=112130292316281&w=2 except that this changes all table addresses, not just ACPI addresses. Matt's original patch was backed out because it caused MCAs on HP sx1000 systems. That problem is resolved by the ioremap() attribute checking added for ia64.
