Yes, Just for amd64:

% grep -r SCALE */include/vmparam.h  | grep define
amd64/include/vmparam.h:#define VM_KMEM_SIZE_SCALE      (1)
arm/include/vmparam.h:#define   VM_KMEM_SIZE_SCALE      (3)
i386/include/vmparam.h:#define  VM_KMEM_SIZE_SCALE      (3)
ia64/include/vmparam.h:#define  VM_KMEM_SIZE_SCALE      (4)
mips/include/vmparam.h:#define  VM_KMEM_SIZE_SCALE      (3)
powerpc/include/vmparam.h:#define       VM_KMEM_SIZE_SCALE      (3)
sparc64/include/vmparam.h:#define       VM_KMEM_SIZE_SCALE
(tsb_kernel_ldd_phys == 0 ? 3 : 2)

cheers,
Hiren
