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.
