[PATCH] kexec: Unusable memory range type

[Cliff Wickman]

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
0008f000-0008ffff : ACPI Non-volatile Storage
00090000-0009ffff : System RAM
00100000-75ffcfff : System RAM
  01000000-0139dcaf : Kernel code
  0139dcb0-0192c12f : Kernel data
  01a28000-01cd7777 : Kernel bss
  02000000-09ffffff : Crash kernel
75ffd000-76013fff : Unusable memory
76014000-766a6fff : System RAM
766a7000-766d6fff : Unusable memory
...

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