[Crash-utility] [PATCH 2/3] mips: set section_size_bits and max_physmem_bits
From: Rabin Vincent <rabinv(a)axis.com>
Enable SPARSEMEM support by setting this two values. It's not clear to
me if they'll work on all MIPS platforms, but they do on the ones I have
access to and should provide reasonable defaults.
