Update ppc for mingo's do_fork changes.  Together with the pmac compile
fixes this allows me to stay at the bleeding edge with my my ibook..

This updates ppc64 for the do_fork() semantics change.

I completely misread this code and there was no bug.  In fact yesterday's fix
broke it.  Revert.

struct page is undefined in this file without this on Alpha.

There is some assembly code in setup.c which doesn't explicitly set its
section.  It comes after a C function which is marked __init.  The compiler
does not reset the section after such C functions.  The assembly code is
going into .text.init.

That's the wrong section.  We get oopses modprobing sctp and, with Manfred's
unmap-free-pages debug patch we get oopses modprobing e100.ko.  In
apply_alternatives().

Support more chips and split out all the complex PHY
handling into a seperate file.

Revert the rtnl_lock API change, it is totally unneeded.
Instead we manage the todo work inside of net/core/dev.c

Also, we have to move sbin hotplug invocation outside of
the RTNL semaphore as well, both for register and unregister.

The AMD K8 GART driver is really for the on-CPU GART not the chipset as the Kconfig described.
Also fix up some grammar elsewhere.

We had two major issues when unregistering networking devices.
1) Even trying to run hotplug asynchronously could deadlock
   if keventd was currently trying to get the RTNL semaphore
   in order to process linkwatch events.
2) Unregister needs to wait for the last reference to go away
   before the finalization of the unregister can execute.  This
   cannot occur under the RTNL semaphore as this is deadlock
   prone as well.

The solution is to do all of this stuff after dropping the
RTNL semaphore.  rtnl_lock, if it is about to protect a region
of code that could unregister network devices, registers a list
to which unregistered netdevs are attached.  At rtnl_unlock time
this list is processed to wait for refcounts to drop to zero and
then finalize the unregister.

This fixes the problem that adapter id's are not the minor number for the
i2c-dev devices anymore.  Also adds a i2c-dev class to let userspace know
which i2c-dev device is bound to which i2c adapter.
