You'll probably need to change the source and compile the kernel. More details depend on distribution and version. – ugoren Jul 16 '13 at 09:57

What do you need this memory for? Do you require it to be physically contiguous? – CL. Jul 16 '13 at 11:23

4If memory is not required to be physically contiguous, you'd better use `vmalloc` which allocates memory region contiguous in virtual memory. – Alexey Shmalko Jul 16 '13 at 11:29
