This avoids comparisons between signed and unsigned integers.

This follows the ARM change, and wires up uImage support on SH, with
all of the same caveats.

This patch adds SuperH crash dump support. The vmlinux loader is modified
with crash dump hooks as on other architectures. SuperH does not need any
backup region, so only the elf header is allocated from the top of the
reserved memory window. The actual size of the memory window is passed
to the secondary kernel on the command line using "mem=".
The secondary kernel must be configured to match the reserved memory
window, change kernel parameters CONFIG_MEMORY_START and CONFIG_MEMORY_SIZE.
Linux-2.6.27 should be usable as primary kernel on SuperH, later kernel
versions are needed to fully support secondary kernel /proc/vmcore.

Add SuperH vmlinux support through a zero-page aware elf loader. Only for
kexec at this point, in the future kdump support will be added.
