Something new I'm adding.

The precedent for this approach is the __HAVE_ARCH_* defines
that let the arch independent stuff know if a generic
function needs to be defined or if there is an arch specific
function.

You can "grep -R __HAVE_ARCH_* arch/x86/" to see the ones
that already exist.

I guess I should have called it
__HAVE_ARCH_LOCAL_TLB_FLUSH_KERNEL_RANGE though, not
__HAVE_LOCAL_TLB_FLUSH_KERNEL_RANGE.
