This commit pulls over the memset() MIPS routine from Linux 2.6.26,
which provides a 10x to 20x speedup over the generic byte-at-a-time
routine. This is especially useful on platforms with manual ECC
scrubbing, that require all of memory to be written at least once
after a power cycle.

Indeed. If it has a deeper meaning,
