All the patches listed above are in Linus' tree.  So here's an updated
patch:



[PATCH] DMI: move dmi_scan.c from arch/i386 to drivers/firmware/

dmi_scan.c is arch-independent and is used by i386, x86_64, and ia64.
Currently all three arches compile it from arch/i386, which means that
ia64 and x86_64 depend on things in arch/i386 that they wouldn't
otherwise care about.

This is simply "mv arch/i386/kernel/dmi_scan.c drivers/firmware/"
(removing trailing whitespace) and the associated Makefile changes.
All three architectures already set CONFIG_DMI in their top-level
Kconfig files.
