Pull powerpc update from Benjamin Herrenschmidt:
"The main highlights this time around are:
- A pile of addition POWER8 bits and nits, such as updated
performance counter support (Michael Ellerman), new branch history
buffer support (Anshuman Khandual), base support for the new PCI
host bridge when not using the hypervisor (Gavin Shan) and other
random related bits and fixes from various contributors.
- Some rework of our page table format by Aneesh Kumar which fixes a
thing or two and paves the way for THP support. THP itself will
not make it this time around however.
- More Freescale updates, including Altivec support on the new e6500
cores, new PCI controller support, and a pile of new boards support
and updates.
- The usual batch of trivial cleanups & fixes"

The Kconfig symbol MAX_ACTIVE_REGIONS is unused. Commit
0ee332c1451869963626bf9cac88f165a90990e1 ("memblock: Kill
early_node_map[]") removed the only place were it was actually used. But
it did not remove its Kconfig entries (for powerpc and sh).
Remove those two entries (and the entry for metag, that popped up in
v3.9-rc1).

The Kconfig symbol ARCH_POPULATES_NODE_MAP was killed in v3.3. After
that it popped up again in microblaze and metag. Nobody noticed,
probably because these Kconfig symbols are entirely unused and these
architectures both select HAVE_MEMBLOCK_NODE_MAP. Anyhow, these two
entries can also be killed.

The metag NUMA implementation follows the SH model, using different nodes for
memories with different latencies. As such, we ensure that automated balancing
between nodes is inhibited, by way of the new ARCH_WANT_VARIABLE_LOCALITY.
