Michael Ellerman d2a3317097 [PATCH] powerpc: Fix typo in topology.h
The fix to topology.h (5cfccd7f13) seems to have
a typeo, struct sched_domain has an idle_idx member but not an idle_id
member. I assume this is the fix.

Nick Piggin 5cfccd7f13 [PATCH] powerpc: Fix database regression due to scheduler changes
PowerPC's NUMA domain doesn't currently set up some of the newer
sched-domains parameters.

Brian Twichell <tbrian@us.ibm.com> discovered and diagnosed a 1.5% OLTP
database regression on a 4 core POWER5 system that was due to the use of
NUMA scheduling on ppc64.

This patch applies some saneish values to the parameters, in line with
other architectures. This solves the regression.

Anton Blanchard 45fb6cea09 [PATCH] ppc64: Convert NUMA to sparsemem (3)
Convert to sparsemem and remove all the discontigmem code in the
process. This has a few advantages:

- The old numa_memory_lookup_table can go away
- All the arch specific discontigmem magic can go away

We also remove the triple pass of memory properties and instead create a
list of per node extents that we iterate through. A final cleanup would
be to change our lmb code to store extents per node, then we can reuse
that information in the numa code.

jdl@freescale.com dd56fdf23d [PATCH] powerpc: Merge a few more include files
Merge a few asm-ppc and asm-ppc64 header files.
Note: the merge of setup.h intentionally does not carry
forward the m68k cruft.  That means this patch continues
to break the already broken amiga on the ppc32.
