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.
Do you intend to comment on the questions and/or submit a cleaned up version of the patch?
Unfortunately, no follow-up patch is forthcoming.
I was able to use a spare DMA engine on our SOC to perform the memory zeroing, which eliminated the need for the enhanced memcopy() routine.
Also, I am not familiar with the intricacies of MIPS exception handling for alignment issues, so I was not able to come up with a good solution for Shinya Kuribayashi's alignment trap issue questions.
Please retract the patch.
