[PATCH] DMI: only ioremap stuff we actually need
dmi_scan_machine() tries to ioremap 0x10000 (64K) bytes, even though it only looks at the first 32 bytes or so. If the SMBIOS table is near the end of a memory region, the ioremap() may fail when it shouldn't. This is in the efi_enabled path, so it really only affects ia64 at the moment.
