kexec: Unusable memory range type
On SGI UV (x86_64) kexec grumbles about 'Unusable memory' ranges:
Unknown type (%s) while parsing %s. Please "
"report this as bug. Using RANGE_RESERVED now.
uv44-sys:~ # cat /proc/iomem
00000000-00000fff : System RAM
00001000-00005fff : reserved
00006000-0008efff : System RAM

This patch keeps Unusable memory as another RANGE_RESERVED area, but
without the warning message.
