Currently the metadata region that holds crash info structure and ELF core
header is placed towards the end of reserved memory area. This patch places
it at the beginning of the reserved memory area. It also introduces
additional dump section called metadata section to communicate location
of metadata region to 2nd kernel. This patch also maintains the
compatibility between production/capture kernels irrespective of their
kernel versions. Both combination older/newer and newer/older works fine.

Trying to look at the patches it might help me if you document reasons
for why this change is made changelog, even if it may be obvious to
someone who knows the code better.

I thought you could include the documentation change in this patch as
well, but maybe that's a matter of preference.

Thanks,
Nick
