Pull VFIO update from Alex Williamson:
"VFIO updates include safer default file flags for VFIO device fds, an
external user interface exported to allow other modules to hold
references to VFIO groups, a fix to test for extended config space on
PCIe and PCI-x, and new hot reset interfaces for PCI devices which
allows the user to do PCI bus/slot resets when all of the devices
affected by the reset are owned by the user.
For this last feature, the PCI bus reset interface, I depend on
changes already merged from Bjorn's PCI pull request. I therefore
merged my tree up to commit cb3e433, which I think was the correct
action, but as Stephen Rothwell noted, I failed to provide a commit

for PL330 MDMA1 device tree node (it was using the wrong addres

by SET_SYSTEM_SLEEP_PM_OPS macro, which is defined under
CONFIG_PM_SLEEP. So if CONFIG_PM_SLEEP is not cofigured but
CONFIG_PM_RUNTIME is, the following warning message appeared:

If we have multiple sessions on a system, we normally don't want
background sessions to read input events. Otherwise, it could capture
passwords and more entered by the user on the foreground session. This is
a real world problem as the recent XMir development showed:
http://mjg59.dreamwidth.org/27327.html
We currently rely on sessions to release input devices when being
deactivated. This relies on trust across sessions. But that's not given on
usual systems. We therefore need a way to control which processes have
access to input devices.
With VTs the kernel simply routed them through the active /dev/ttyX. This
is not possible with evdev devices, though. Moreover, we want to avoid
routing input-devices through some dispatcher-daemon in userspace (which
would add some latency).
This patch introduces EVIOCREVOKE. If called on an evdev fd, this revokes
device-access irrecoverably for that *single* open-file. Hence, once you
call EVIOCREVOKE on any dup()ed fd, all fds for that open-file will be
rather useless now (but still valid compared to close()!). This allows us
to pass fds directly to session-processes from a trusted source. The
source keeps a dup()ed fd and revokes access once the session-process is
no longer active.
Compared to the EVIOCMUTE proposal, we can avoid the CAP_SYS_ADMIN
restriction now as there is no way to revive the fd again. Hence, a user
is free to call EVIOCREVOKE themself to kill the fd.
Additionally, this ioctl allows multi-layer access-control (again compared
to EVIOCMUTE which was limited to one layer via CAP_SYS_ADMIN). A middle
layer can simply request a new open-file from the layer above and pass it
to the layer below. Now each layer can call EVIOCREVOKE on the fds to
revoke access for all layers below, at the expense of one fd per layer.
There's already ongoing experimental user-space work which demonstrates
how it can be used:

"Input: introduce BTN/ABS bits for drums and guitars"
"HID: wiimote: add support for Guitar-Hero drums"
"HID: wiimote: add support for Guitar-Hero guitars"
The extra new ABS_xx values resulted in ABS_MAX no longer being a

We'll try again for 3.13.

The spec suggests that we should use _OST to notify the platform
about the status of notifications it sends us, for example so that
it doesn't repeate a notification that has been handled already.
This turns out to help reduce the amount of diagnostic output from

generates multiple device check notifies for PCIe devices on the root
bus during boot.

Sometimes we may get a spurious device check or bus check notify for
a hotplug device and in those cases we should avoid doing all of the
configuration work needed when something actually changes. To that
end, check the return value of pci_scan_slot() in enable_slot() and
bail out early if it is 0.
This turns out to help reduce the amount of diagnostic output from

i915: Update VGA arbiter support for newer devices
caused i915 to disable VGA memory decode for the IGD when i915 is
initializing. Unfortunately that happens before the vgacon->fbcon
handoff so vgacon_save_screen() will read out all ones from the
VGA memory.
After the handoff fbcon will inherit the bogus state from vgacon,
and pre-fills the fb with matching contents. The end result is
a white rectangle in the top left corner of the screen, the size
of which matches the now inactive VGA console.
To remedy the situation delay the disabling of VGA memory until
the vgacon->fbcon handoff has happened.
Also rename i915_enable_vga to i915_enable_vga_mem to make
the relationship between these functions clearer.

Pull ARM SoC board updates from Olof Johansson:
"Board updates for 3.12. Again, a bit of domain overlap with SoC and
DT branches, but most of this is around legacy code and board support.
We've found that platform maintainers have a hard time separating all
of these out and might move towards fewer branches for next release.
- Removal of a number of Marvell Kirkwood board files, since contents
is now common and mostly configured via DT.
- Device-tree updates for Marvell Dove, including irqchip and
clocksource setup.
- Defconfig updates. Gotta go somewhere. One new one for Renesas
Lager.
- New backlight drivers for backlights used on Renesas shmobile
platforms.
- Removal of Renesas leds driver.
- Shuffling of some of the new Broadcom platforms to give room for
others in the same mach directory. More in 3.13"

Since the _get_rate() helper has been modified to use __clk_lookup()
internally, checking of PLL input rates can be done using it and so the
registration code can be simplified.

This patch adds rate tables for PLLs that can be reconfigured at runtime
for Exynos4x12 SoCs. Provided tables contain PLL coefficients for
input clock of 24 MHz and so are registered only in this case. MPLL does
not need runtime reconfiguration and so table for it is not provided.

There is no need to use clkdev inside the clock driver to retrieve the

Pull ARM SoC platform changes from Olof Johansson:
"This branch contains mostly additions and changes to platform
enablement and SoC-level drivers. Since there's sometimes a
dependency on device-tree changes, there's also a fair amount of
those in this branch.
Pieces worth mentioning are:
- Mbus driver for Marvell platforms, allowing kernel configuration
and resource allocation of on-chip peripherals.
- Enablement of the mbus infrastructure from Marvell PCI-e drivers.
- Preparation of MSI support for Marvell platforms.
- Addition of new PCI-e host controller driver for Tegra platforms
- Some churn caused by sharing of macro names between i.MX 6Q and 6DL
platforms in the device tree sources and header files.
- Various suspend/PM updates for Tegra, including LP1 support.
- Versatile Express support for MCPM, part of big little support.
- Allwinner platform support for A20 and A31 SoCs (dual and quad
Cortex-A7)
- OMAP2+ support for DRA7, a new Cortex-A15-based SoC.
The code that touches other architectures are patches moving MSI
arch-specific functions over to weak symbols and removal of
ARCH_SUPPORTS_MSI, acked by PCI maintainers"

A recent patch made it possible to bring up the character handle when the

recent patch moved the initialization that requires we move where the
checks for this condition occur. This patch merges these two ideas so
it works much as before.
