drm/radeon/kms: fix the regression of DVI connector check
The check of the encoder type in the commit [
e00e8b5e: drm/radeon/kms:
fix analog load detection on DVI-I connectors] is obviously wrong, and
it's the culprit of the regression on my workstation with DVI-analog
connection resulting in the blank output.
Fixed the typo now.

HID: default HID_BATTERY_STRENGTH to no
Commit
4f5ca836b "HID: hid-input: add support for HID devices reporting
Battery Strength" added the CONFIG_HID_BATTERY_STRENGTH option to report
the battery strength of HID devices. The commit log explicitly mentions
it not working properly with recent userspace, but it is default y

but it's for oldpage, and needs now to be for newpage. Once oldpage was

KVM: lock slots_lock around device assignment
As pointed out by Jason Baron, when assigning a device to a guest
we first set the iommu domain pointer, which enables mapping
and unmapping of memory slots to the iommu. This leaves a window
where this path is enabled, but we haven't synchronized the iommu
mappings to the existing memory slots. Thus a slot being removed
at that point could send us down unexpected code paths removing
non-existent pinnings and iommu mappings. Take the slots_lock
around creating the iommu domain and initial mappings as well as
around iommu teardown to avoid this race.

However, actually pch_uart_verify_port() is called during

As a result, memory access violation occurs like below.
0. initial value: use_dma=0
1. starup()
- dma channel is not allocated because use_dma=0
2. pch_uart_verify_port()
- Set use_dma=1
3. UART processing acts DMA mode because use_dma=1

Newer BKDG[1] versions recommend a different initialization value for

Updated BIOSes will have this new value set up from the beginning,

This needs to be done on all northbridges, even on those where the
driver itself does not register at.
This fixes the driver on all current machines to provide proper

This reverts commit
6fe0d0628245fdcd6fad8b837c81e8f7ebc3364d.
Paul bisected this regression.
The conversion was done blindly and is wrong, as it does not provide a
primary handler to disable the level type irq on the device level.
Neither does it set the IRQF_ONESHOT flag which handles that at the irq
line level. This can't be done as the interrupt might be shared, though
we might extend the core to force it.
So an interrupt on this line will wake up the thread, but immediately
unmask the irq after that. Due to the interrupt being level type the
hardware interrupt is raised over and over and prevents the irq thread
from handling it. Fail.
request_irq() unfortunately does not refuse such a request and the patch
was obviously never tested with real interrupts.

freed memory further down in the function when we index into 'ap[]'.
Since we don't actually need 'ap' until after the use of the
RESIZE_IF_NEEDED macro we can just delay the assignment to it until
after we've potentially resized, thus avoiding the issue.
While I was there anyway I also changed the integer variable 'n' to be

EHCI: fix criterion for resuming the root hub
This patch (as1542) changes the criterion ehci-hcd uses to tell when
it needs to resume the controller's root hub. A resume is needed when
a port status change is detected, obviously, but only if the root hub
is currently suspended.
Right now the driver tests whether the root hub is running, and that
is not the correct test. In particular, if the controller has died
then the root hub should not be restarted. In addition, some buggy
hardware occasionally requires the root hub to be running and
sending out SOF packets even while it is nominally supposed to be
suspended.
In the end, the test needs to be changed. Rather than checking whether
the root hub is currently running, the driver will now check whether
the root hub is currently suspended. This will yield the correct
behavior in all cases.

USB: fix deadlock in bConfigurationValue attribute method
This patch (as154) fixes a self-deadlock that occurs when userspace
writes to the bConfigurationValue sysfs attribute for a hub with
children. The task tries to lock the bandwidth_mutex at a time when
it already owns the lock:
The attribute's method calls usb_set_configuration(),
which calls usb_disable_device() with the bandwidth_mutex
held.
usb_disable_device() unregisters the existing interfaces,
which causes the hub driver to be unbound.
The hub_disconnect() routine calls hub_quiesce(), which
calls usb_disconnect() for each of the hub's children.
usb_disconnect() attempts to acquire the bandwidth_mutex
around a call to usb_disable_device().
The solution is to make usb_disable_device() acquire the mutex for
itself instead of requiring the caller to hold it. Then the mutex can
cover only the bandwidth deallocation operation and not the region
where the interfaces are unregistered.
This has the potential to change system behavior slightly when a
config change races with another config or altsetting change. Some of
the bandwidth released from the old config might get claimed by the
other config or altsetting, make it impossible to restore the old
config in case of a failure. But since we don't try to recover from
config-change failures anyway, this doesn't matter.
[This should be marked for stable kernels that contain the commit
fccf4e86200b8f5edd9a65da26f150e32ba79808 "USB: Free bandwidth when
usb_disable_device is called."

ARM: OMAP: serial: Fix the ocp smart idlemode handling bug
The current serial UART code, while fidling with ocp idlemode bits,
forget about the smart idle wakeup bit even if it is supported by
UART IP block. This will lead to missing the module wakeup on OMAP's
where the smart idle wakeup is supported.
This was the root cause of the console sluggishness issue, I have been
observing on OMAP4 devices and also can be potential reason for some
other UART wakeup issues.

ARM: OMAP2+: UART: Fix incorrect population of default uart pads
Commit (7496ba3 ARM: OMAP2+: UART: Add default mux for all uarts)
wrongly added muxing of default pads for all uarts. This causes
breakage on multiple boards using uart pins for alternate functions.
For example, on zoom3 random oopses can be seen with nfsroot as
the smsc911x ethernet FIFO timings on GPMC bus are controlled
by gpmc_wait2 and gpmc_wait3 pins. This means we can't mux these
pads to uart4 functionality as commit 7496ba3 was doing.
Not all boards tend to use all uarts and most of unused uart pins
are muxed for other purpose. This commit breaks the modules which
where trying to use unused uart pins on their boards.
So remove the default pad muxing. Note that this is not a complete
fix, as we now rely on bootloader set muxing for the uart wake-up
events. Further patching is needed to enable wake-up events for
uarts that are already muxed to uart mode.

PCI: Retry BARs restoration for Type 0 headers only
Some shortcomings introduced into pci_restore_state() by commit
26f41062f28d ("PCI: check for pci bar restore completion and retry")
have been fixed by recent commit
ebfc5b802fa76 ("PCI: Fix regression in
pci_restore_state(), v3"), but that commit treats all PCI devices as
those with Type 0 configuration headers.
That is not entirely correct, because Type 1 and Type 2 headers have
different layouts. In particular, the area occupied by BARs in Type 0
config headers contains the secondary status register in Type 1 ones and
it doesn't make sense to retry the restoration of that register even if
the value read back from it after a write is not the same as the written
one (it very well may be different).
For this reason, make pci_restore_state() only retry the restoration
of BARs for Type 0 config headers. This effectively makes it behave
as before commit
26f41062f28d for all header types except for Type 0.

Michel Lespinasse cleaned up the futex calling conventions in commit

But the ia64 implementation was subtly broken. Gcc does not know that
register "r8" will be updated by the fault handler if the cmpxchg
instruction takes an exception. So it feels safe in letting the
initialization of r8 slide to after the cmpxchg. Result: we always
return 0 whether the user address faulted or not.
Fix by moving the initialization of r8 into the __asm__ code so gcc
won't move it.

drm/i915: don't clobber the special upscaling lvds timings
This regression has been introduced in
commit

drm/i915: fixup interlaced vertical timings confusion, part 1
Unfortunately that commit failed to take into account that the lvds
code does some special adjustements to the crtc timings for upscaling
an centering.
Fix this by explicitly computing crtc timings in the lvds mode fixup
function and setting a special flag in mode->private_flags if the crtc
timings have been adjusted.
v2: Add a comment to explain the new mode driver private flag,
suggested by Eugeni Dodonov.
v3: Kill the confusing and now redundant set_crtcinfo call in
intel_fixed_panel_mode, noticed by Chris Wilson.

- The SOC config options are now brought in by default
- No need to explicitly select misc devices anymore
- I2C is selected by default
- We now have support for charging from the AB8500 so compile
in this
- The regulator framework needs to be explictly selected
