Commit 43fef47f94 (mfd: twl4030-power: Add a configuration to turn
off oscillator during off-idle) added support for configuring the PMIC
to cut off resources during deeper idle states to save power.
This however caused regression for n900 display power that needed the
PMIC configuration to be disabled with commit d937678ab6 (ARM: dts:
Revert enabling of twl configuration for n900).
Turns out the root cause of the problem is that we must use
TWL4030_RESCONFIG_UNDEF instead of DEV_GRP_NULL to avoid disabling
regulators that may have been enabled before the init function
for twl4030-power.c runs. With TWL4030_RESCONFIG_UNDEF we let the
regulator framework control the regulators like it should. Here we
need to only configure the sys_clken and sys_off_mode triggers for
the regulators that cannot be done by the regulator framework as
it's not running at that point.
This allows us to enable the PMIC configuration for n900.

The nocb callbacks generated before the nocb kthreads are spawned are
enqueued in the nocb queue for later processing. Commit fbce7497ee ("rcu:
Parallelize and economize NOCB kthread wakeups") introduced nocb leader kthreads
which checked the nocb_leader_wake flag to see if there were any such pending
callbacks. A case was reported in which newly spawned leader kthreads were not
processing the pending callbacks as this flag was not set, which led to a boot
hang.
The following commit ensures that the newly spawned nocb kthreads process the
pending callbacks by allowing the kthreads to run immediately after spawning
instead of waiting. This is done by inverting the logic of nocb_leader_wake
tests to nocb_leader_sleep which allows us to use the default initialization of
this flag to 0 to let the kthreads run.

I've received a bug report from a user that the touchpad control part
of the ideapad-laptop ACPI interface does work for him on his
"Lenovo Yoga 2 13", and that this patch causes a regression for him.
Since it did not work for me when I had a "Lenovo Yoga 2 11" in my own
hands (loaned from a friend). It seems that this is a bit of hit and miss.
Since the result of having a false positive here is worse, then the minor
annoyance of a false touchpad disabled messages being shown after suspend /
resume on models (or is it firmware versions?) where the interface does not
work, simply revert the patch.
This reverts commit f79a901331.

The __init annotations for the DMI callback functions are wrong as this
code can be called even after the module has been initialized, e.g. like
this:
# echo 1 > /sys/bus/pci/devices/0000:00:02.0/remove
# modprobe i915
# echo 1 > /sys/bus/pci/rescan
The first command will remove the PCI device from the kernel's device
list so the second command won't see it right away. But as it registers
a PCI driver it'll see it on the third command. If the system happens to
match one of the DMI table entries we'll try to call a function in long
released memory and generate an Oops, at best.
Fix this by removing the bogus annotation.
Modpost should have caught that one but it ignores section reference
mismatches from the .rodata section. :/

This resolves a problem introduced by a0f7e7496d
("ARM: shmobile: sh73a0: add CMT1 clock support for DT")
which was included in v3.17-rc1.
This fix does not have any run-time affect at this time as the clock in
question is used by a SCIF device that is not enabled by default.

If we assign a Radeon device to a virtual machine, we can no longer
assume a fixed hardware topology, like the GPU having a parent device.
This patch simply adds a few pci_is_root_bus() tests to avoid passing
a NULL pointer to PCI access functions, allowing the radeon driver to
work in a QEMU 440FX machine with an assigned HD8570 on the emulated
PCI root bus.

This is a bit bigger hammer then I would like to use for this, but for now
it will have to make do. I'm working on getting my hands on one of these so
that I can try to get streams to work (with a quirk flag if necessary) and
then we can re-enable them.
For now this at least makes uas capable disk enclosures work again by forcing
fallback to the usb-storage driver.

condition variable (waiters_pending) was set before being added to
the poll queue via poll_wait(). This allowed for a small race window
to happen where an event could come in, check the condition variable
see it set to true, clear it, and then wake all the waiters. But because
the waiter set the variable before adding itself to the queue, the
waker could have cleared the variable after it was set and then miss
waking it up as it wasn't added to the queue yet.
Discussing this bug, we realized that a memory barrier needed to be added
too, for the rare case that something polls for a single trace event
to happen (and just one, no more to come in), and miss the wakeup due
to memory ordering. Ideally, a memory barrier needs to be added on the
writer side too, but as that will kill tracing performance and this is
for a situation that tracing wasn't even designed for (who traces one
instance of an event, use a printk instead!), this isn't worth adding the
barrier. But we can in the future add the barrier for when the buffer
goes from empty to the first event, as that would cover this case.
