Benjamin Herrenschmidt 3dcfb74fd4 ppc: Fix tlb invalidations on 6xx/7xx/7xxx 32-bit processors 
The processor only uses some bits of the address and invalidates an
entire congruence class. Some OSes such as Darwin and HelenOS take
advantage of this and occasionally invalidate the entire TLB by just
doing a series of 64 consecutive tlbie for example.

Our code tries to be too smart here only invalidating a segment
congruence class (ie, allowing more address bits to be relevant
in the invalidation), this fails miserably on those OSes.

Instead don't bother, do like ppc64 and blow the whole tlb when tlbie
is executed.
