According to the specifications, vmalloc is limited only by the amount of physical memory on your machine. However, Arjan VanDeVen has a point. Other process are already using physical memory (like the kernel process), and those process count against the physical memory available.
TIP: It's always nice to leave at least 20% of the physical memory free for other critical processes, especially those that can't be swapped out.
