Jason Gunthorpe abf35df215 NET: Support clause 45 MDIO commands at the MDIO bus level
IEEE 802.3ae clause 45 specifies a somewhat modified MDIO protocol
for use by 10GIGE phys. The main change is a 21 bit address split into
a 5 bit device ID and a 16 bit register offset. The definition is designed
so that normal and extended devices can run on the same MDIO bus.

Extend mdio-bitbang to do the new protocol. At the MDIO bus level the
protocol is requested by or'ing MII_ADDR_C45 into the register offset.

Make phy_read/phy_write/etc pass a full 32 bit register offset.

This does not attempt to make the phy layer support C45 style PHYs, just
to provide the MDIO bus support.

Tested against a Broadcom 10GE phy with ID 0x206034, and several
Broadcom 10/100/1000 Phys in normal mode.

Rafael J. Wysocki 23606cf5d1 e1000e / PCI / PM: Add basic runtime PM support (rev. 4)
Use the PCI runtime power management framework to add basic PCI
runtime PM support to the e1000e driver.  Namely, make the driver
suspend the device when the link is off and set it up for generating
a wakeup event after the link has been detected again.  [This
feature is disabled until the user space enables it with the help of
the /sys/devices/.../power/contol device attribute.]

Based on a patch from Matthew Garrett.

James Chapman c3259c8a70 l2tp: Fix UDP socket reference count bugs in the pppol2tp driver
This patch fixes UDP socket refcnt bugs in the pppol2tp driver.

A bug can cause a kernel stack trace when a tunnel socket is closed.

A way to reproduce the issue is to prepare the UDP socket for L2TP (by
opening a tunnel pppol2tp socket) and then close it before any L2TP
sessions are added to it. The sequence is

Create UDP socket
Create tunnel pppol2tp socket to prepare UDP socket for L2TP
  pppol2tp_connect: session_id=0, peer_session_id=0
L2TP SCCRP control frame received (tunnel_id==0)
  pppol2tp_recv_core: sock_hold()
  pppol2tp_recv_core: sock_put
L2TP ZLB control frame received (tunnel_id=nnn)
  pppol2tp_recv_core: sock_hold()
  pppol2tp_recv_core: sock_put
Close tunnel management socket
  pppol2tp_release: session_id=0, peer_session_id=0
Close UDP socket
  udp_lib_close: BUG

The addition of sock_hold() in pppol2tp_connect() solves the problem.

For data frames, two sock_put() calls were added to plug a refcnt leak
per received data frame. The ref that is grabbed at the top of
pppol2tp_recv_core() must always be released, but this wasn't done for
accepted data frames or data frames discarded because of bad UDP
checksums. This leak meant that any UDP socket that had passed L2TP
data traffic (i.e. L2TP data frames, not just L2TP control frames)
using pppol2tp would not be released by the kernel.

Ian Munsie 8b4017d8c1 i4l: silence compiler warnings for array access in Eicon DIVA ISDN driver
When compiling this driver, the compiler throws the following warnings:

drivers/isdn/hardware/eicon/message.c:8426: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8427: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8434: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8435: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8436: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8447: warning: array subscript is above array bounds

This arises from the particular semantics the driver is using to write to
the nlc array (static byte[256]).  The array has a length in byte 0
followed by a T30_INFO struct starting at byte 1.

The T30_INFO struct has a number of variable length strings after the
station_id entry, which cannot be explicitly defined in the struct and the
driver accesses them with an array index to station_id beyond the length
of station_id.

This patch merely changes the semantics that the driver uses to access the
entries after the station_id entry to use the original 256 byte nlc array
taking the offset and length of the station_id entry to calculate where to
write in the array, thereby silencing the warning.

Since we want to keep ordering of write to fp->bd_tx_cons and

Ajit Khaparde d4a2ac3e80 be2net: fix mccq create for big endian architectures
The request to create an mccq was being dispatched without
doing a byte swap of num_pages. This byte swap is necessary
for Big Endian systems like PPC. Not having this fix leads
mccq create to fail on BE ASICs running newer version of
firmware, thereby causing driver initialization failure.

Sekhar Nori be5bce2bf5 net: davinci emac: use dma_{map, unmap}_single API for cache coherency
The davinci emac driver uses some ARM specific DMA APIs
for cache coherency which have been removed from kernel
with the 2.6.34 merge.

Modify the driver to use the dma_{map, unmap}_single() APIs
defined in dma-mapping.h

Without this fix, the driver fails to compile on Linus's
tree.

Tested on DM365 and OMAP-L138 EVMs.

and

commit 70abc8cb90

This introduced a problem that can happen if the TX ring size
is increased.  We need to size the PCI pool using cbs->max

Now that the early _PDC evaluation path knows how to correctly
evaluate _PDC on only physically present processors, there's no
need for the processor driver to evaluate it later when it loads.

To cover the hotplug case, push _PDC evaluation down into the
hotplug paths.

Detect if a processor is physically present before evaluating _PDC.

We want this because some BIOS will provide a _PDC even for processors
that are not present. These bogus _PDC methods then attempt to load
non-existent tables, which causes problems.

Avoid those bogus landmines.

We've renamed the old processor_core.c to processor_driver.c, to
convey the idea that it can be built modular and has driver-like
bits.

Now let's re-create a processor_core.c for the bits needed
statically by the rest of the kernel. The contents of processor_pdc.c
are a good starting spot, so let's just rename that file and
complete our three card monte.

Alex Chiang 0131aa3dd7 ACPI: processor: mv processor_core.c processor_driver.c
The ACPI processor driver can be built as a module. But it has
pieces of code that should always be built statically into the
kernel.

The plan is for processor_core.c to contain the static bits while
processor_driver.c contains the module-like bits.

Since the bulk of the code in the current processor_core.c is
module-like, first step is to rename the file to processor_driver.c

Next step will re-create processor_core.c and cherry-pick out
the static bits.
