74521c28e5 Use i8253.c lock for PC speaker on MIPS, too.
The Jazz machines have to use the PIT timer for dyntick and highresolution
kernels.  This may break because currently just like i386 used to do MIPS
uses two separate spinlocks in the actual PIT code and the PC speaker
code.  So switch to do it the same that x86 currently does PIT locking.

kernel at the same time just to make sure that at least one driver will suceed
in find it's mouse device. Nevertheless, only the inport and logitech busmouse
mouse drivers report with KERN_ERR log level if the mouse wasn't found. They
should use KERN_INFO instead, because it's not an error if the mouse isn't
attached at all.

c956a24018 Fix myri10ge NAPI oops & warnings
When testing the myri10ge driver with 2.6.24-rc1, I found
that the machine crashed under heavy load:

Unable to handle kernel paging request at 0000000000100108 RIP:
  [<ffffffff803cc8dd>] net_rx_action+0x11b/0x184

The address corresponds to the list_move_tail() in
netif_rx_complete():
                     if (unlikely(work == weight))
                             list_move_tail(&n->poll_list, list);

Eventually, I traced the crashes to calling netif_rx_complete() with
work_done == budget.  From looking at other drivers, it appears that
one should only call netif_rx_complete() when work_done < budget.

To fix it, I changed the test in myri10ge_poll() so that it refers
to to work_done rather than looking at the rx ring status.  If
work_done is < budget, then that implies we have no more packets to
process. Any races will be resolved by the NIC when the write to
irq_claim is made.

In myri10ge_clean_rx_done(), if we ever exceeded our budget, it would
report a work_done one larger than was acutally done.  This is because
the increment was done in the conditional, so work_done would be
incremented regardless of whether or not the test passed or failed.
This would lead to the WARN_ON_ONCE(work > weight); warning in
net_rx_action triggering.  I've moved the increment of work_done
inside the loop.  Note that this would only be a problem when we had
exceeded our budget.

644fdf9b08 mpc5200: Fix Kconfig dependancies on MPC5200 FEC device driver
When not building an arch/powerpc kernel, the mpc5200 FEC driver depends
on some symbols which are not defined (BESTCOMM & BESTCOMM_FEC).

This patch flips around the dependancy logic so that it cannot be
selected unless BESTCOMM_FEC is selected first.  Kconfig stops
complaining this way.

Also, the driver only works for arch/powerpc (not arch/ppc) anyway so
it should depend on PPC_MERGE also.

The setup_net is called for the init net namespace
only (int the CONFIG_NET_NS=n of course) from the __init
function, so mark it as __net_init to disappear with the
caller after the boot.

Yet again, in the perfect world this has to be under
#ifdef CONFIG_NET_NS, but it isn't guaranteed that every
subsystem is registered *after* the init_net_ns is set
up. After we are sure, that we don't start registering
them before the init net setup, we'll be able to move
this code under the ifdef.

6a1a3b9f68 [NET]: Hide the dead code in the net_namespace.c
The namespace creation/destruction code is never called
if the CONFIG_NET_NS is n, so it's OK to move it under
appropriate ifdef.

The copy_net_ns() in the "n" case checks for flags and
returns -EINVAL when new net ns is requested. In a perfect
world this stub must be in net_namespace.h, but this
function need to know the CLONE_NEWNET value and thus
requires sched.h. On the other hand this header is to be
injected into almost every .c file in the networking code,
and making all this code depend on the sched.h is a
suicidal attempt.

1dba323b3f [NETNS]: Make the init/exit hooks checks outside the loop
When the new pernet something (subsys, device or operations) is
being registered, the init callback is to be called for each
namespace, that currently exitst in the system. During the
unregister, the same is to be done with the exit callback.

However, not every pernet something has both calls, but the
check for the appropriate pointer to be not NULL is performed
inside the for_each_net() loop.

This is (at least) strange, so tune this.
