272aa3966b V4L/DVB (11568): cx18: Fix the handling of i2c bus registration error
* Return actual error values as returned by the i2c subsystem, rather
  than 0 or 1.
* If the registration of the second bus fails, unregister the first one
  before exiting, otherwise we are leaking resources.

a357482a1e V4L/DVB (11561a): move media after i2c
Currently drivers/media drivers are linked very early - directly after
base, block, misc, and mfd and before ata, scsi, ide, input, firewire,
usb, and i2c. This breaks static build of video4linux drivers, that use
generic CPU i2c adapter drivers and the v4l2-subdev subsystem, because
during video4linux probing the v4l2-subdev core requires a struct
i2c_adapter context, which cannot be satisfied before the i2c subsystem is
initialised. Moving drivers/media after drivers/i2c fixes this problem.

The best way to trigger action is by submitting a patch:-) So, let's see
what comes out of it - on the one hand I don't see any reason why media
has to be linked this early, and nobody was able to give me one yesterday
as this problem has been discussed on linux-media, OTOH, maybe indeed it
would be better to move i2c the whole way up above media, but that'd be
much bigger of a change, I think.

e5b89542ea virtio-rng: Remove false BUG for spurious callbacks
The virtio-rng drivers checks for spurious callbacks. Since
callbacks can be implemented via shared interrupts (e.g. PCI) this
could lead to guest kernel oopses with lots of virtio devices.

f3c737de8f umem: fix request_queue lock warning
The umem driver issues two warnings on boot, due to blk_plug_device() and
blk_remove_plug() being called without q->queue_lock held.  Starting with
e48ec690 (block: extend queue_flag bitops), the queue_flag_* functions
warn if q->queue_lock doesn't appear to be locked.  In fact, q->queue_lock
is NULL (though that apparently isn't otherwise a problem as the driver is
using card->lock for everything).

Although blk_init_queue() with take a request_fn_proc and spinlock_t*,
there isn't a corresponding init helper that takes a make_request_fn.
Setting queue_lock to &card->lock explicitly seems to work fine for me.
The warning goes away and the device appears to behave.

b7f0ab460f ACPI, i915: Register ACPI video even when not modesetting
The ACPI video driver defers registration to the i915 driver if the
system supports opregion-mediated backlight control. This registration
was only being performed in the KMS case. Ensure it's done even if we
don't have modesetting enabled.

53005a0a1b sony-laptop: always try to unblock rfkill on load
This fixes an inconsistent behaviour when loading the driver with the
switch on or off. In the former case you would also need to soft unblock
the switch via the sysfs file entries to really disable rfkill, in the
latter you wouldn't.

5aa63f038f ACPI: EC: Fix ACPI EC resume non-query interrupt message
When resuming from standby (on a laptop) I see the following message in
my kernel.log:
"ACPI: EC: non-query interrupt received, switching to interrupt mode"
This apparently prevented sony-laptop to properly restore the brightness
level on resume.

The cause: In drivers/acpi/ec.c the acpi_ec_suspend function clears the
GPE mode bit, but this is not restored in acpi_ec_resume (the function
below it). The patch below fixes this by properly restoring the GPE_MODE
bit. Tested and confirmed to work.

f461ddea0a ACPI/hpet: prevent boot hang when hpet=force used on ICH-4M
Linux tells ICH4 users that they can (manually) invoke
"hpet=force" to enable the undocumented ICH-4M HPET.
The HPET becomes available for both clocksource and clockevents.

But as of ff69f2bba6
(acpi: fix of pmtimer overflow that make Cx states time incorrect)
the HPET may be used via clocksource for idle accounting, and
hpet=force on an ICH4 box hangs boot.

It turns out that touching the MMIO HPET withing
the ARB_DIS part of C3 will hang the hardware.

The fix is to simply move the timer access outside
the ARB_DIS region.  This is a no-op on modern hardware
because ARB_DIS is no longer used.

fdd8b079e3 [ARM] 5460/1: Orion: reduce namespace pollution
Symbols like SOFT_RESET are way too generic to be exported at large.
To avoid this, let's move the mbus bridge register defines into a
separate file and include it where needed.  This affects mach-kirkwood,
mach-loki, mach-mv78xx0 and mach-orion5x simultaneously as they all
share code in plat-orion which relies on those defines.

Some other defines have been moved to narrower scopes, or simply deleted
when they had no user.

This fixes compilation problem with mpt2sas on the above listed
platforms.
