Description: Fix infinite recursion when alignment passed is 0 in function
aligned_kmalloc(), in file drivers/atm/firestream.c. Also, a negative value for
alignment does not make sense. Check for negative value too.
The function prototype is:
static void __devinit *aligned_kmalloc (int size, gfp_t flags,
int alignment).
