This adds support for analyzing dumps from 32-bit MIPS.
I've uploaded some sample dumps generated from the QEMU MIPS Malta machine
(little-endian) at the following location:

Hello Dave,
The patch is used to display qemu note of compressed qemu memory dump.
It is against the newest git. Please check.
This is good -- I'm adding a few small display changes and will
test the patch overnight.

I found something is missing in the committed patch. In dump_Elf64_Nhdr, qemu
note of X86
is not available to call display_ELF_note. The process is like below:
if (BITS32() type == NT_PRSTATUS)
display_ELF_note

Hello,
I have a couple dumps generated on Ubuntu Trusty LTS (3.13.0-39-generic
kernel) which crash fails on.

For virtual address with idmap, we just use VTOP to
do the translate. So we should not use one way for
arm and LPAE enabled arm.
This bugs occurs when the phys_base exceeds 4G. So
we could not meet this bugs at most case. But for
