This patch converts cpmac to the new Fixed PHY infrastructure, though it
doesn't fix all the problems with that driver. I didn't even bother to
test this patch to compile, because cpmac driver is broken in several ways:

1. This driver won't compile by itself because lack of its header describing
   platform data;
2. It assumes that fixed PHYs should be created by the ethernet driver.
   It is wrong assumption: fixed PHYs creation is platform code authority,
   driver must blindly accept bus_id and phy_id platform data variables
   instead.

Also, it seem that that driver doesn't have actual in-tree users, so
nothing to fix further.

The main purpose of that patch is to get rid of the following Kconfig
warning:

scripts/kconfig/conf -s arch/powerpc/Kconfig
drivers/net/Kconfig:1713:warning: 'select' used by config symbol
'CPMAC' refers to undefined symbol 'FIXED_MII_100_FDX'

Add a parameter to add_partial instead of having separate functions.  The
parameter allows a more detailed control of where the slab pages is placed in
the partial queues.

If we put slabs back to the front then they are likely immediately used for
allocations.  If they are put at the end then we can maximize the time that
the partial slabs spent without being subject to allocations.

When deactivating slab we can put the slabs that had remote objects freed (we
can see that because objects were put on the freelist that requires locks) to
them at the end of the list so that the cachelines of remote processors can
cool down.  Slabs that had objects from the local cpu freed to them (objects
exist in the lockless freelist) are put in the front of the list to be reused
ASAP in order to exploit the cache hot state of the local cpu.

Patch seems to slightly improve tbench speed (1-2%).

Because hpet_rtc_interrupt()'s call to get_rtc_time() ends up
resolving to include/asm-generic/rtc.h's (hilariously inlined)
get_rtc_time(), which does spin_unlock_irq() from hard IRQ context.

The obvious patch fixes it.
