Subject[patch] modify data types in efi.h
David, Bjorn,

Here's a small patch against 2.6.0-test2 to change several data types from u64 to unsigned long in efi.h. These changes enable the use of the same data structures and function prototypes for ia32 EFI kernels. Comments?

Please apply...

thanks,
matt
