Since Herb was talking about using the memory for a large array, I recommended the API that I'd normally tell people to use for that usage. If this array was actually a driver DMA target, well, then one of the other options is probably a better bet. Regardless of whether the memory is likely to be a DMA target or not, allocating pageable kernel memory is probably the way to go. The sole exception to this case is when the memory is likely to be accessed on the paging path; typically anything in interrupt context or on the low-level I/O path.
