H A D | tlbflush.h | f048aace Thu Dec 18 13:13:38 CST 2008 Benjamin Herrenschmidt <benh@kernel.crashing.org> powerpc/mm: Add SMP support to no-hash TLB handling
This commit moves the whole no-hash TLB handling out of line into a new tlb_nohash.c file, and implements some basic SMP support using IPIs and/or broadcast tlbivax instructions.
Note that I'm using local invalidations for D->I cache coherency.
At worst, if another processor is trying to execute the same and has the old entry in its TLB, it will just take a fault and re-do the TLB flush locally (it won't re-do the cache flush in any case).
