This change helps to address locking issues seen with
netif_set_real_num_tx_queues and netif_set_real_num_rx_queues when used in
the igb_set_interrupt_capability function. To resolve these locking issues
I have moved the two function calls into __igb_open so that they can be
called while the RTNL lock is held.
An added advantage to this is that the number of queues is not updated
until the last possible moment so if there are any issues in allocating
MSI-X interrupts or resources for the rings we have time to change the

spanning buffers and does not need to be worried about the actual supported

When enabling DCB the rings belonging to a q_vector on CPU 0 were not
reinitializing their DCA registers. Upon closer inspection the issue was
that the q_vector CPU variable was left at 0 resulting in the driver not
updating the DCA registers.
In order to guarantee the DCA registers will be updated I am adding a
couple line change so that we initialize the CPU variable to -1 which will
force a DCA update the first time an interrupt fires on that q_vector.
In addition we were setting the CPU affinity hint to all CPUs when we were
not specifying a CPU. Instead we should leave it as all zeros to avoid any
possible confusion about the fact that we shouldn't be giving a hint.

The recovery thread, when failing, tears down the respective interface. To do
so, it needs to obtain the rtnl lock first, as the interface configuration is
changed.
If another process tries to modify an interface setting at the same time, that
process can obtain the rtnl lock first, but the respective callback in the qeth
driver will block until recovery has completed - which cannot happen since the
calling process already obtained it.
In one particular case, the bonding driver acquired the rtnl lock to modify the
card's MAC address, while the recovery failed at the same time due to the card
being removed. Hence qeth_l2_set_mac_address (implicitly holding the rtnl lock)
was waiting on qeth_l2_recover, which deadlocked when waiting on the rtnl lock.
This patch uses rtnl_trylock instead of rtnl_lock in the recovery thread. If the
lock cannot be obtained, the interface will be left up, but the card state
remains in CARD_STATE_RECOVER, which will prevent any further activities on the
card.

Commit 0236141837 ("thermal: add generic cpufreq cooling
implementation") requires cpufreq_frequency_get_table(), but that
function is only defined for CONFIG_CPU_FREQ_TABLE resulting in the
following build error:
drivers/built-in.o: In function `cpufreq_get_max_state':
drivers/thermal/cpu_cooling.c:259: undefined reference to `cpufreq_frequency_get_table'
drivers/built-in.o: In function `get_cpu_frequency':
drivers/thermal/cpu_cooling.c:129: undefined reference to `cpufreq_frequency_get_table'
Fix it by selecting CONFIG_CPU_FREQ_TABLE for such a configuration.
It turns out CONFIG_EXYNOS_THERMAL also needs CONFIG_CPU_FREQ_TABLE, so
select it there as well.

radeon_i2c_fini() walks thru the list of I2C bus recs rdev->i2c_bus[]
to destroy each of them.
radeon_ext_tmds_enc_destroy() however also has code to destroy it's
associated I2C bus rec which has been obtained by radeon_i2c_lookup()
and is therefore also in the i2c_bus[] list.
This causes a double free resulting in a kernel panic when unloading
the radeon driver.
Removing destroy code from radeon_ext_tmds_enc_destroy() fixes this
problem.

Based on Dmitries work, but splitting the code into page
directory and page table handling makes it far more
readable and (hopefully) more reliable.
Allocations of page tables are made from the SA on demand,
that should still work fine since all page tables are of
the same size.
Also using the fact that allocations from the SA are mostly
continuously (except for end of buffer wraps and under very
high memory pressure) to group updates send to the chipset
specific code into larger chunks.

The compilation of the pinctrl driver failed on the legacy
Nomadik NHK8815 platform because it was not providing the PRCMU
interfaces needed to support the extended alternate functions
used by the ux500 series.
Solve this by providing some stubs for the legacy platform, to
avoid too much #ifdefs in the code per se. Theoretically this
actually allows the Nomadik and Ux500 to have a single kernel
image with support for the PRCM registers on the Ux500 (though
they have incompatible archs, but the spirit is there).

The prima2 platform advertises needing no mach/gpio.h header file,
but its pinctrl driver now has a sirfsoc_gpio_set_pull function
that uses constants defined in arch/arm/mach-prima2/include/mach/gpio.h,
which fails to build.
Fortunately, the sirfsoc_gpio_set_pull is not used anywhere in the
kernel, so we can safely remove it. Any out of tree drivers using
it will have to be converted to use proper pinctrl functions to
do the same.
Without this patch, building prima2_defconfig results in:
drivers/pinctrl/pinctrl-sirf.c: In function 'sirfsoc_gpio_set_pull':
drivers/pinctrl/pinctrl-sirf.c:1331:7: error: 'SIRFSOC_GPIO_PULL_NONE' undeclared (first use in this function)

The samsung pinctrl driver has a probe function that is
__devinit and that calls a lot of other functions that are
marked __init, which kbuild complains about.
Marking everything __devinit means that the code does not
discarded when CONFIG_HOTPLUG is set, which is a little
more wasteful, but also more consistent
Without this patch, building exynos_defconfig results in:
WARNING: drivers/pinctrl/built-in.o(.devinit.text+0x124): Section mismatch in reference from the function samsung_pinctrl_probe() to the function .init.text:samsung_gpiolib_register()
The function __devinit samsung_pinctrl_probe() references
a function __init samsung_gpiolib_register().
If samsung_gpiolib_register is only used by samsung_pinctrl_probe then
annotate samsung_gpiolib_register with a matching annotation.
