The number of permutations of crap we do is amazing and almost all of it
has the wrong effect in 2.6.

At the heart of this is the PCI SFF magic which says that compatibility
mode PCI IDE controllers use ISA IRQ routing and hard coded addresses
not the BAR values. The old quirks variously clears them, sets them,
adjusts them and then IDE ignores the result.

In order to drive all this garbage out and to do it portably we need to
handle the SFF rules directly and properly. Because we know the device
BAR 0-3 are not used in compatibility mode we load them with the values
that are implied (and indeed which many controllers actually
thoughtfully put there in this mode anyway).

This removes special cases in the IDE layer and libata which now knows
that bar 0/1/2/3 always contain the correct address. It means our
resource allocation map is accurate from boot, not "mostly accurate"
after ide is loaded, and it shoots lots of code. There is also lots more
code and magic constant knowledge to shoot once this is in and settled.

Been in my test tree for a while both with drivers/ide and with libata.
Wants some -mm shakedown in case I've missed something dumb or there are
corner cases lurking.

Shouldn't PCI-X state be saved/restored?  No device really needs this

It's all good.

This changes the type of variable "i" in rtl8169_init_one()
from "unsigned int" to "int". "i" is checked for < 0 later,
which can never happen for "unsigned". This results in broken
error handling.

  [NETFILTER]: ctnetlink: fix reference count leak
  [NETFILTER]: nf_conntrack: fix the race on assign helper to new conntrack
  [NETFILTER]: nfctnetlink: assign helper to newly created conntrack

MAX_HEADER is either set to LL_MAX_HEADER or LL_MAX_HEADER + 48, and
this is controlled by a set of CONFIG_* ifdef tests.

It is trying to use LL_MAX_HEADER + 48 when any of the tunnels are
enabled which set hard_header_len like this:

dev->hard_header_len = LL_MAX_HEADER + sizeof(struct xxx);

The correct set of tunnel drivers which do this are:

ipip
ip_gre
ip6_tunnel
sit

so make the ifdef test match.

Noticed by Patrick McHardy and with help from Herbert Xu.
