[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. Signed-off-by: Jay Lan <jlan@sgi.com> Acked-by: Simon Horman <horms@verge.net.au> Signed-off-by: Tony Luck <tony.luck@intel.com>
