[PATCH] FRV: Permit large kmalloc allocations [try #2]
Permit kmalloc() to make allocations of up to 32MB if so configured. This may be useful under NOMMU conditions where vmalloc() can't do this. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
