X-Git-Tag: v2.6.17-rc1~648

[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.
