Jesse Larrew	36f567b429	powerpc: Add VPHN firmware feature ... This simple patch adds the firmware feature for VPHN to the firmware features bitmask. Signed-off-by: Jesse Larrew <jlarrew@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>	2010-11-29 15:48:22 +11:00
Anton Blanchard	b6dcde5c74	powerpc: Fix hypervisor TLB batching ... Profiling of a page fault scalability microbenchmark shows flush_hash_range is not calling the batch hpte invalidate hcall (H_BULK_REMOVE). It turns out we have a duplicate firmware feature for hcall-bulk and the current setup code stops after finding the first match. This meant we never batch and always do individual invalidates. The patch below removes the duplicate and shifts FW_FEATURE_CMO to close the gap. With the patch applied the single threaded page fault rate improves from 217169 to 238755 per second on a POWER5 test box, a 10% improvement.

Stephen Rothwell	b8b572e101	powerpc: Move include files to arch/powerpc/include/asm ... from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where <asm-powepc/...> was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc.
