The netlink conflict dealt with moving to netlink_capable() and
netlink_ns_capable() in the 'net' tree vs. supporting 'tc' operations
in non-init namespaces. These were simple transformations from
netlink_capable to netlink_ns_capable.

The Altera driver conflict was simply code removal overlapping some
void pointer cast cleanups in net-next.

Pull ACPI and power management fixes from Rafael Wysocki:
"A bunch of regression fixes this time. They fix two regressions in
the PNP subsystem, one in the ACPI processor driver and one in the
ACPI EC driver, four cpufreq driver regressions and an unrelated bug
in one of the drivers. The regressions are recent or introduced in
3.14.

Specifics:

- There are two bugs in the ACPI PNP core that cause errors to be
returned if optional ACPI methods are not present. After an ACPI
core change made in 3.14 one of those errors leads to serial port
suspend failures on some systems. Fix from Rafael J Wysocki.

- A recently added PNP quirk related to Intel chipsets intorduced a
build error in unusual configurations (PNP without PCI). Fix from
Bjorn Helgaas.

- An ACPI EC workaround related to system suspend on Samsung machines
added in 3.14 introduced a race causing some valid EC events to be
discarded. Fix from Kieran Clancy.

- The acpi-cpufreq driver fails to load on some systems after a 3.14
commit related to APIC ID parsing that overlooked one corner case.
Fix from Lan Tianyu.

- Fix for a recently introduced build problem in the ppc-corenet
cpufreq driver from Tim Gardner.

- A recent cpufreq core change to ensure serialization of frequency
transitions for drivers with a ->target_index() callback overlooked
the fact that some of those drivers had been doing operations
introduced by it into the core already by themselves. That
resulted in a mess in which the core and the drivers try to do the
same thing and block each other which leads to deadlocks. Fixes
for the powernow-k7, powernow-k6, and longhaul cpufreq drivers from
Srivatsa S Bhat.

- Fix for a computational error in the powernow-k6 cpufreq driver
from Srivatsa S Bhat"

cpufreq: powernow-k6: Fix double invocation of cpufreq_freq_transition_begin/end

During frequency transitions, the cpufreq core takes the responsibility of
invoking cpufreq_freq_transition_begin() and cpufreq_freq_transition_end()
for those cpufreq drivers that define the ->target_index callback but don't
set the ASYNC_NOTIFICATION flag.

The powernow-k6 cpufreq driver falls under this category, but this driver was
invoking the _begin() and _end() APIs itself around frequency transitions,
which led to double invocation of the _begin() API. The _begin API makes
contending callers wait until the previous invocation is complete. Hence,
the powernow-k6 driver ended up waiting on itself, leading to system hangs
during boot.

Fix this by removing the calls to the _begin() and _end() APIs from the
powernow-k6 driver, since they rightly belong to the cpufreq core.

(Note that during ->exit(), the powernow-k6 driver sets the frequency
without any help from the cpufreq core. So add explicit calls to the
_begin() and _end() APIs around that frequency transition alone, to take
care of that special case. Also, add a missing 'break' statement there.)

a couple of cpufreq drivers introduced during the 3.14 cycle),
assorted ACPI cleanups, wakeup framework documentation fixes, a new
sysfs attribute for cpuidle and a new command line argument for power
domains diagnostics.

Specifics:

- Fix for a recently introduced CPU hotplug regression in ARM KVM
from Ming Lei.

residency information to user space from Daniel Lezcano.

- New kernel command line argument to prevent power domains enabled
by the bootloader from being turned off even if they are not in use

Uytterhoeven.

cpufreq: create another field .flags in cpufreq_frequency_table

Currently cpufreq frequency table has two fields: frequency and driver_data.
driver_data is only for drivers' internal use and cpufreq core shouldn't use
it at all. But with the introduction of BOOST frequencies, this assumption
was broken and we started using it as a flag instead.

There are two problems due to this:
- It is against the description of this field, as driver's data is used by
the core now.
- if drivers fill it with -3 for any frequency, then those frequencies are
never considered by cpufreq core as it is exactly same as value of
CPUFREQ_BOOST_FREQ, i.e. ~2.

The best way to get this fixed is by creating another field flags which
will be used for such flags. This patch does that. Along with that various
drivers need modifications due to the change of struct cpufreq_frequency_table.
