And I recomend a new kernel interface, and Dan, I KNOW YOU WILL not like THE VERY IDEA, by here it is. I beleive that a kmalloc_little_endian and a kmalloc_nocache should be added to the port. The ability to allocate a little endian memory would by defaut handle conversion in a seamless and quick manner. copy_from_user and copy_to_use would then do the bit to little endian conversions. By the same token, an interface to allocate noncached memory would be spiffy. I would also assist in the porting of device drivers that need lots of little non cached spaces like scsi and USB drivers.
