Instead of doing byte-at-a-time user accesses to figure
out where the fault occurred, read the saved fault_address
from the current thread structure.

For the sake of defensive programming, if the fault_address
does not fall into the user buffer range, simply assume the
whole area faulted.  This will cause the fixup for
copy_from_user() to clear the entire kernel side buffer.

We were not calling kernel_mna_trap_fault() correctly.
Instead of being fancy, just return 0 vs. -EFAULT from
the assembler stubs, and handle that return value as
appropriate.

Create an "__retl_efault" stub for assembler exception
table entries and use it where possible.

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.

In order to do it correctly on UltraSPARC-III+ and later we'd

register before loading the TLB.

Since this optimization gives questionable gains, it's best to
just remove it for now instead of adding the fix for Ultra-III+

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.
