Changed ppc32 so that cur_cpu_spec is just a single pointer for all CPUs.
Additionally, made call_setup_cpu check to see if the cpu_setup pointer
is NULL or not before calling the function. This lets remove the dummy
cpu_setup calls that just return.

Merged cputable.h between ppc32 and ppc64. In doing this removed support
for the BEGIN_FTR_SECTION/END_FTR_SECTION macros in C code since they
dont compile correctly. C code should use cpu_has_feature(). This is
based on Arnd Bergmann's initial patch.

powerpc: Merge byteorder.h
Essentially adopts the 64-bit version of this file. The 32-bit version had
been using unsigned ints for arguments/return values that were actually
only 16 bits - the new file uses __u16 for these items as in the 64-bit
version of the header. The order of some of the asm constraints
in the 64-bit version was slightly different than the 32-bit version,
but they produce identical code.

Fix 5780 PHY related problems:
1. MAC_RX_MODE reset must be done before setting up the MAC_MODE
register on 5705_PLUS chips or the chip will stop receiving after
a while. The MAC_RX_MODE reset is needed to prevent intermittently
losing the first receive packet on serdes chips.
2. Skip MAC loopback test on 5780 because of hardware errata. Normal
traffic including PHY loopback is not affected by the errata.
3. PHY loopback fails intermittently on 5708S and this is fixed by
putting the PHY in loopback mode first before programming the MAC
mode register. A MAC_RX_MODE reset is also added.
4. Return -EINVAL in tg3_nway_reset() if device is in TBI mode. Allow
nway_reset if 5780S is in parallel detect mode.
5. Add missing PHY IDs in KNOWN_PHY_ID() macro.

arm maketools needs include/asm-arm in place in the build tree.
On normal builds it's always there, of course, but on O= it's created
(by generic code) too late - when we get to asm-offset.h.
We used to get away with that by accident - creation of
include/asm-arm/arch symlink creates include/asm-arm and it happened
to go before maketools. However, we did not have such dependency,
so that luck didn't last - now maketools is picked first and we are screwed.
Both the symlink and maketools are prerequisites of the same
target (archprepare). This fix is obvious - make the latter explicitly
depend on the former and be done with that.

When you've enabled conntrack and NAT as a module (standard case in all
distributions), and you've also enabled the new conntrack netlink
interface, loading ip_conntrack_netlink.ko will auto-load iptable_nat.ko.
This causes a huge performance penalty, since for every packet you iterate
the nat code, even if you don't want it.
This patch splits iptable_nat.ko into the NAT core (ip_nat.ko) and the
iptables frontend (iptable_nat.ko). Threfore, ip_conntrack_netlink.ko will
only pull ip_nat.ko, but not the frontend. ip_nat.ko will "only" allocate
some resources, but not affect runtime performance.
This separation is also a nice step in anticipation of new packet filters
(nf-hipac, ipset, pkttables) being able to use the NAT core.
