    [PATCH] ia64: use i386 dmi_scan.c · 3ed3bce8

    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.
