Jay Lan d3758f87f3 [IA64] kexec fails on systems with blocks of uncached memory 
Currently a memory segment in memory map with attribute of EFI_MEMORY_UC
is denoted as "System RAM" in /proc/iomem, while memory of attribute
(EFI_MEMORY_WB|EFI_MEMORY_UC) is also labeled the same.

The kexec utility then includes uncached memory as part of vmcore. The
kdump kernel MCA'ed when it tries to save the vmcore to a disk. A normal
"cached" access may cause MCAs.

This patch would label memory with attribute of EFI_MEMORY_UC only as
"Uncached RAM" so that kexec would know not to include it in the vmcore.
I will submit a separate kexec-tools patch to the kexec list.
