QXL is a paravirtual graphics device used by the Spice virtual desktop
interface.

The drivers uses GEM and TTM to manage memory, the qxl hw fencing however
is quite different than normal TTM expects, we have to keep track of a number
of non-linear fence ids per bo that we need to have released by the hardware.

The releases are freed from a workqueue that wakes up and processes the
release ring.

releases are suballocated from a BO, there are 3 release categories, drawables,
surfaces and cursor cmds. The hw also has 3 rings for commands, cursor and release handling.

The hardware also have a surface id tracking mechnaism and the driver encapsulates it completely inside the kernel, userspace never sees the actual hw surface
ids.

This requires a newer version of the QXL userspace driver, so shouldn't be
enabled until that has been placed into your distro of choice.

Authors: Dave Airlie, Alon Levy

v1.1: fixup some issues in the ioctl interface with padding
v1.2: add module device table
v1.3: fix nomodeset, fbcon leak, dumb bo create, release ring irq,
      don't try flush release ring (broken hw), fix -modesetting.
v1.4: fbcon cpu usage reduction + suitable accel flags.

Prevent compiler from re-fetching mm->mmap_cache, because other

Since kernel 3.7, it appears that the input registration occured before
the end of magicmouse_setup_input(). This is shown by receiving a lot of
"EV_SYN SYN_REPORT 1" instead of normal "EV_SYN SYN_REPORT 0".
This value means that the output buffer is full, and the user space
is loosing events.

Using .input_configured guarantees that the race is not occuring, and that
the call of "input_set_events_per_packet(input, 60)" is taken into account
by input_register().

CONFIG_LPAE doesn't exist: the correct option is CONFIG_ARM_LPAE, so fix
up the two typos under arch/arm/.

The fix to head.S is slightly scary, but this is just for setting up
an early io-mapping for the serial port when running on a big-endian,
LPAE system. Since these systems don't exist in the wild (at least, I
have no access to one outside of kvmtool, which doesn't provide a serial
port suitable for earlyprintk), then we can revisit the code later if it
causes any problems.

Commit 70264367 ("ARM: 7653/2: do not scale loops_per_jiffy when
using a constant delay clock") fixed a problem with our timer-based
delay loop, where loops_per_jiffy is scaled by cpufreq yet used directly
by the timer delay ops.

This patch fixes the problem in a more elegant way by keeping a private
ticks_per_jiffy field in the delay ops, independent of loops_per_jiffy
and therefore not subject to scaling. The loop-based delay continues to
use loops_per_jiffy directly, as it should.

On Cortex-A15 (r0p0..r3p2) the TLBI/DSB are not adequately shooting down
all use of the old entries. This patch implements the erratum workaround
which consists of:

1. Dummy TLBIMVAIS and DSB on the CPU doing the TLBI operation.
2. Send IPI to the CPUs that are running the same mm (and ASID) as the
   one being invalidated (or all the online CPUs for global pages).
3. CPU receiving the IPI executes a DMB and CLREX (part of the exception
   return code already).

Commit b8db6b88 (ARM: 7547/4: cache-l2x0: add support for Aurora L2 cache
ctrl) moved the masking of the part ID which caused the RTL version to be
lost. Commit 6248d060 (ARM: 7545/1: cache-l2x0: make outer_cache_fns a
field of l2x0_of_data) changed how .set_debug is initialized. Both commits
break commit 74ddcdb8 (ARM: 7608/1: l2x0: Only set .set_debug
on PL310 r3p0 and earlier) which uses the RTL version to conditionally set
.set_debug function pointer. Commit b8db6b88 also caused the printed cache
ID to be missing the version information.

Fix this by reverting how the part number is masked so the RTL version
info is maintained. The cache-id-part DT property does not set the RTL
bits so masking them should have no effect. Also, re-arrange the order
of the function pointer init so the .set_debug function can be overridden.

The VMCI context ID of a virtual machine may change at any time. There
is a VMCI event which signals this but datagrams may be processed before
this is handled. It is therefore necessary to be flexible about the
destination context ID of any datagrams received. (It can be assumed to
be correct because it is provided by the hypervisor.) The context ID on
existing sockets should be updated to reflect how the hypervisor is
currently referring to the system.

IPv6 Routing table becomes broken once we do ifdown, ifup of the loopback(lo)
interface. After down-up, routes of other interface's IPv6 addresses through
'lo' are lost.

IPv6 addresses assigned to all interfaces are routed through 'lo' for internal
communication. Once 'lo' is down, those routing entries are removed from routing
table. But those removed entries are not being re-created properly when 'lo' is
brought up. So IPv6 addresses of other interfaces becomes unreachable from the
same machine. Also this breaks communication with other machines because of
NDISC packet processing failure.

This patch fixes this issue by reading all interface's IPv6 addresses and adding
them to IPv6 routing table while bringing up 'lo'.

currently cbq works incorrectly for limits > 10% real link bandwidth,
and practically does not work for limits > 50% real link bandwidth.
Below are results of experiments taken on 1 Gbit link

 In shaper | Actual Result
-----------+---------------
  100M     | 108 Mbps
  200M     | 244 Mbps
  300M     | 412 Mbps
  500M     | 893 Mbps

This happen because of q->now changes incorrectly in cbq_dequeue():
when it is called before real end of packet transmitting,
L2T is greater than real time delay, q_now gets an extra boost
but never compensate it.

To fix this problem we prevent change of q->now until its synchronization
with real time.

Make sure that msg pointer is set back to error value in case of
MSG_COPY flag is set and desired message to copy wasn't found.  This
garantees that msg is either a error pointer or a copy address.

Otherwise the last message in queue will be freed without unlinking from
the queue (which leads to memory corruption) and the dummy allocated
copy won't be released.

Now that netdev_rx_handler_unregister contains synchronize_net(), we need
to call it outside of bond->lock, cause it might sleep. Also, remove the

Pull ARM SoC bug fixes from Arnd Bergmann:
 "After a quiet set of fixes for 3.9-rc4, a lot of people woke up and
  sent urgent fixes for 3.9.  I pushed back on a number of them that got
  deferred to 3.10, but these are the ones that seemed important.

  Regression in 3.9:

   - Multiple regressions in OMAP2+ clock cleanup
   - SH-Mobile frame buffer bug fix that merged here because of
     maintainer MIA
   - ux500 prcmu changes broke DT booting
   - MMCI duplicated regulator setup on ux500
   - New ux500 clock driver broke ethernet on snowball
   - Local interrupt driver for mvebu broke ethernet
   - MVEBU GPIO driver did not get set up right on Orion DT
   - incorrect interrupt number on Orion crypto for DT

  Long-standing bugs, including candidates for stable:

   - Kirkwood MMC needs to disable invalid card detect pins
   - MV SDIO pinmux was wrong on Mirabox
   - GoFlex Net board file needs to set NAND chip delay
   - MSM timer restart race
   - ep93xx early debug code broke in 3.7
   - i.MX CPU hotplug race
   - Incorrect clock setup for OMAP1 USB
   - Workaround for bad clock setup by some old OMAP4 boot loaders
   - Static I/O mappings on cns3xxx since 3.2"

From Anton Vorontsov <anton@enomsg.org>:

This tag includes Mac Lin's work to revive CNS3xxx booting:

 "Since commit 0536bdf3 (ARM: move iotable mappings within the vmalloc
 region), [...] the pre-defined iotable mappings is not in the vmalloc
 region. [...] move the iotable mappings into the vmalloc region, and
 merge the MPCore private memory region (containing the SCU, the GIC and
 the TWD) as a single region."

Plus there is a small cosmetic fix, also from Mac Lin.
