[NET]: Define infrastructure to keep 'inuse' changes in an efficent SMP/NUMA way.
"struct proto" currently uses an array stats[NR_CPUS] to track change on
'inuse' sockets per protocol.
If NR_CPUS is big, this means we use a big memory area for this.
Moreover, all this memory area is located on a single node on NUMA
machines, increasing memory pressure on the boot node.
In this patch, I tried to :
- Keep a fast !CONFIG_SMP implementation
- Keep a fast CONFIG_SMP implementation for often used protocols
(tcp,udp,raw,...)
- Introduce a NUMA efficient implementation
Some helper macros are defined in include/net/sock.h
These macros take into account CONFIG_SMP
If a "struct proto" is declared without using DEFINE_PROTO_INUSE /
REF_PROTO_INUSE
macros, it will automatically use a default implementation, using a
dynamically allocated percpu zone.
This default implementation will be NUMA efficient, but might use 32/64
bytes per possible cpu
because of current alloc_percpu() implementation.
However it still should be better than previous implementation based on
stats[NR_CPUS] field.
When a "struct proto" is changed to use the new macros, we use a single
static "int" percpu variable,
lowering the memory and cpu costs, still preserving NUMA efficiency.

[PPP]: L2TP: Fix oops in transmit and receive paths
Changes made on 18-sep to fix skb handling in the pppol2tp driver
broke the transmit and receive paths. Users are only running into this
now because distros are now using 2.6.23 and I must have messed up
when I tested the change.
For receive, we now do our own calculation of how much to pull from
the skb (variable length L2TP header) rather than using
skb_transport_offset(). Also, if the skb isn't a data packet, it must
be passed back to UDP with skb->data pointing to the UDP header.
For transmit, make sure skb->sk is set up because ip_queue_xmit()
needs it.

leds: bugfixes for leds-gpio
Three bugfixes to the leds-gpio driver, plus minor whitespace tweaks:
- Do the INIT_WORK() before registering each LED, so if its trigger
becomes immediately active it can schedule work without oopsing..
- Use normal registration, not platform_driver_probe(), so that
devices appearing "late" (hotplug type) can still be bound.
- Mark the driver remove code as "__devexit", preventing oopses
when the underlying device is removed.
These issues came up when using this driver with some GPIO expanders
living on serial busses, which act unlike "normal" platform devices:
they can appear and vanish along with the serial bus driver.

MSI does not work on the PCIX bus because the BIOS did not set the

bridge. We use the existing quirk_msi_ht_cap() to detect the problem
and disable MSI in all buses behind it.

In piix.c (and in ata_piix.c) are already included some patches to skip the
cable check on some laptops and to enable UDMA > 33 modes, but I've noticed
than theese doesn't work on my Acer Aspire 5602WLMi (maybe exist more
versions of this laptop). With this simple patch I can set transfer mode

SLUB: Fix memory leak by not reusing cpu_slab
Fix the memory leak that may occur when we attempt to reuse a cpu_slab
that was allocated while we reenabled interrupts in order to be able to
grow a slab cache.
The per cpu freelist may contain objects and in that situation we may
overwrite the per cpu freelist pointer loosing objects. This only
occurs if we find that the concurrently allocated slab fits our
allocation needs.
If we simply always deactivate the slab then the freelist will be
properly reintegrated and the memory leak will go away.

The Time of Day clock is the standard time source for s390. It is
- monotonic
- allows very fast reading
- architecture guarantees at least microsecond stepping
- available as part of the architecture
We should announce the rate of tod as 400 to be in sync with the
description found in clocksource.h:
"400-499:Perfect The ideal clocksource. A must-use where available."
This change will prefer tod over less reliable clock sources.
