These function parameters are incorrect for the callbacks. Luckily the
functions don't actually do anything, so the code still "works" just
fine...

This comes directly from the Realtek tarball, filename:
wifi_driver_8821ae_0018.1129.2013.tar.gz
I mushed the three modules (btcoexist, rtlwifi and rtl8821ae) together
into one, in order to make it all build as one stand-alone module.
After the btcoexist driver gets merged upstream, I'll pull it out of
here, and will continue to work on removing this version of rtlwifi in
order to use the in-kernel one.

The head number of a given display controller is fixed in hardware and
required to program outputs appropriately. Relying on the driver probe
order to determine this number will not work, since that could yield a
situation where the second head was probed first and would be assigned
head number 0 instead of 1.
By explicitly specifying the head number in the device tree, it is no
longer necessary to rely on these assumptions. As a fallback, if the
property isn't available, derive the head number from the display
controller node's position in the device tree. That's somewhat more
reliable than the previous default but not a proper solution.

Input GPIO changes can generate interrupts, but we need kind of ACK for
them by changing IRQ polarity. This is required to stop hardware from
keep generating interrupts and generate another one on the next GPIO
state change.
This code allows using GPIOs with standard interrupts and add for
example GPIO buttons support.

After booting without a working link, "ip link" shows:
5: mlx4_ib1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 2044 qdisc pfifo_fast
state DOWN qlen 256
...
7: mlx4_ib1.8003@mlx4_ib1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 2044 qdisc
pfifo_fast state DOWN qlen 256
...
Then after connecting and disconnecting the link, which should result
in exactly the same state as before, it shows:
5: mlx4_ib1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 2044 qdisc pfifo_fast
state DOWN qlen 256
...
7: mlx4_ib1.8003@mlx4_ib1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 2044 qdisc
pfifo_fast state LOWERLAYERDOWN qlen 256
...
Notice the (now correct) LOWERLAYERDOWN operstate shown for the
mlx4_ib1.8003 interface. Ideally the identical state would be shown
right after boot.
The problem is related to the calling of netif_carrier_off() in
network drivers. For a long time it was known that doing
netif_carrier_off() before registering the netdevice would result in
the interface's operstate being shown as UNKNOWN if the device was
brought up without a working link. This problem was fixed in commit
8f4cccbbd92 ('net: Set device operstate at registration time'), but
still there remains the minor inconsistency demonstrated above.
This patch fixes it by moving ipoib's call to netif_carrier_off() into
the .ndo_open method, which is where network drivers ordinarily do it.
With the patch when doing the same test as above, the operstate of
mlx4_ib1.8003 is shown as LOWERLAYERDOWN right after boot.

Pull Xen updates from Konrad Rzeszutek Wilk:
"Two major features that Xen community is excited about:
The first is event channel scalability by David Vrabel - we switch
over from an two-level per-cpu bitmap of events (IRQs) - to an FIFO
queue with priorities. This lets us be able to handle more events,
have lower latency, and better scalability. Good stuff.
The other is PVH by Mukesh Rathor. In short, PV is a mode where the
kernel lets the hypervisor program page-tables, segments, etc. With
EPT/NPT capabilities in current processors, the overhead of doing this
in an HVM (Hardware Virtual Machine) container is much lower than the
hypervisor doing it for us.
In short we let a PV guest run without doing page-table, segment,
syscall, etc updates through the hypervisor - instead it is all done
within the guest container. It is a "hybrid" PV - hence the 'PVH'
name - a PV guest within an HVM container.
The major benefits are less code to deal with - for example we only
use one function from the the pv_mmu_ops (which has 39 function
calls); faster performance for syscall (no context switches into the
hypervisor); less traps on various operations; etc.
It is still being baked - the ABI is not yet set in stone. But it is
pretty awesome and we are excited about it.
Lastly, there are some changes to ARM code - you should get a simple
conflict which has been resolved in #linux-next.
In short, this pull has awesome features.
Features:
- FIFO event channels. Key advantages: support for over 100,000
events (2^17), 16 different event priorities, improved fairness in
event latency through the use of FIFOs.
- Xen PVH support. "It’s a fully PV kernel mode, running with
paravirtualized disk and network, paravirtualized interrupts and
timers, no emulated devices of any kind (and thus no qemu), no BIOS
or legacy boot — but instead of requiring PV MMU, it uses the HVM
hardware extensions to virtualize the pagetables, as well as system
calls and other privileged operations." (from "The
Paravirtualization Spectrum, Part 2: From poles to a spectrum")
Bug-fixes:
- Fixes in balloon driver (refactor and make it work under ARM)
- Allow xenfb to be used in HVM guests.
- Allow xen_platform_pci=0 to work properly.
- Refactors in event channels"
