In commit 7bced39751,
dma_cookie was removed from struct skbuff.
But the description of dma_cookie still exist.
So the "make xmldocs" output following warning.
Warning(.//include/linux/skbuff.h:609): Excess struct/union
/enum/typedef member 'dma_cookie' description in 'sk_buff'

The tx_desc struct holds 8 __be64 values. The original code in
ring_tx_db() took a tx_desc pointer then casted it to an int pointer and
then casted it to a u64 pointer. It was confusing and triggered some
static checker warnings.
I have changed the cxgb_pio_copy() function to only take tx_desc
pointers. This isn't really a loss of flexibility because anything else
was buggy to begin with.
I also removed the casting on the destination pointer since that was
unnecessary and a bit messy.

sb_edac controls a large number of different PCI functions. Rather
than registering as a normal PCI driver for all of them, it
registers for just one so that it gets probed and, at probe time, it
looks for all the others.
Coincidentally, the device it registers for also contains the SMBUS
registers, so the PCI core will refuse to probe both sb_edac and a
future iMC SMBUS driver. The drivers don't actually conflict, so
just change sb_edac's device table to probe a different device.
An alternative fix would be to merge the two drivers, but sb_edac
will also refuse to load on non-ECC systems, whereas i2c_imc would
still be useful without ECC.
The only user-visible change should be that sb_edac appears to bind
a different device.

This commit changes sb_edac to forward a channel of -1 to EDAC if the

====================
net: fs_enet: Remove non NAPI RX and add NAPI for TX
When using a MPC8xx as a router, 'perf' shows a significant time spent in
fs_enet_interrupt() and fs_enet_start_xmit().
'perf annotate' shows that the time spent in fs_enet_start_xmit is indeed spent
between spin_unlock_irqrestore() and the following instruction, hence in
interrupt handling. This is due to the TX complete interrupt that fires after
each transmitted packet.
This patchset first remove all non NAPI handling as NAPI has become the only
mode for RX, then adds NAPI for handling TX complete.
This improves NAT TCP throughput by 21% on MPC885 with FEC.

RTL8168EP is Realtek PCIe Gigabit Ethernet controller with DASH support.
It is a successor chip of RTL8168DP.
For RTL8168EP, the read/write ocp register is via eri channel type 2, so I
move ocp_xxx() related functions under rtl_eri_xxx. And use r8168dp_ocp_xxx()
for RTL8168DP ocp read/write, r8168ep_ocp_xxx() for RTL8168EP ocp read/write.
The way of checking dash enable is different with RTL8168DP. I use
r8168dp_check_dash()for RTL8168DP and r8168ep_check_dash() for RTL8168EP,
to check if dash is enabled.
The driver_start() and driver_stop() of RTL8168EP is also different with
RTL8168DP. I use rtl8168dp_driver_xxx() for RTL8168DP and
rtl8168ep_driver_xxx for RTL8168EP.
Right now, RTL8168EP phy mcu did not need firmware code patch, so I did not
add firmware code for it.

When @gfp is specified, the percpu allocator is interested in whether
it contains all of GFP_KERNEL or not. If it does, the normal
allocation path is taken; otherwise, the atomic allocation path.
Unfortunately, pcpu_alloc() was incorrectly testing for whether @gfp
contains any part of GFP_KERNEL.
Fix it by testing "(gfp & GFP_KERNEL) != GFP_KERNEL" instead of
"!(gfp & GFP_KERNEL)" to decide whether the allocation should be

Here is the big staging patch set for 3.18-rc1.
Once again, we are deleting more code than we added, with something like
150000 lines deleted overall. Some of this is due to drivers being
added to the networking tree, so the old versions are removed here, but
even then, the overall difference is quite good.
Other than driver deletions, lots and lots and lots of minor cleanups
all over the place. Full details are in the shortlog below.

- s390 moves closer towards host large page support
- PowerPC has improved support for debugging (both inside the guest and
via gdbstub) and support for e6500 processors
- ARM/ARM64 support read-only memory (which is necessary to put firmware
in emulated NOR flash)
- x86 has the usual emulator fixes and nested virtualization improvements
(including improved Windows support on Intel and Jailhouse hypervisor
support on AMD), adaptive PLE which helps overcommitting of huge guests.
Also included are some patches that make KVM more friendly to memory
hot-unplug, and fixes for rare caching bugs.
Two patches have trivial mm/ parts that were acked by Rik and Andrew.

Commit 7bced39751 ("net_dma: simple removal") removed the long-dead
net_dma code, but unintentionally broke the build for the qualcomm
crypto engine (qce) that had accidentally depended on the inclusion of
<linux/dmaengine.h> through the networking header files that used to
have it.
Add the required dmaengine.h include explicitly to fix the breakage.

Pull HID updates from Jiri Kosina:
- quirk for devices that need to be pulled in much more aggresive way
than mandated, by Johan Hovold
- robustification of sanity checking of incoming reports in RMI driver,
by Benjamin Tissoires
- fixes, updates, and new HW support to SONY driver, by Frank Praznik

compliant and they should work in the future without any modification
of the kernel. Written by Benjamin Tissoires.
- a lot more simple fixes and device ID additions all over the place
