Crash doesn't detect the highmem addresses.

Hi,

While debugging panic triggered by kernel modules in Interaptiv MIPS
platform, I see that that crash doesn't decode the high mem addresses
as the crash notes depend upon "System RAM" regions in /proc/iomem.

# cat /proc/iomem | grep -i "System"
00044000-042fffff : System RAM
09b00000-0d1fffff : System RAM

But highmem regions(0x20000000 onwards on this platform) are not
included in that segment due to following code in resource_init:

732         if (start >= HIGHMEM_START)
733             continue;

Any reason why highmem is not parsed under resource_init? How can
crash decode the high mem addresses correctly if the region is not
specified in /proc/iomem?

Thanks
Sagar
