One peripheral may share part of its pins with the 2nd

pinctrl: imx: work around select input quirk
The select input for some pin may not be implemented using the regular
select input register but the general purpose register. A real example
is that imx6q designers found the select input for USB OTG ID pin is
missing at the very late stage, and can not add a new select input
register but have to use a general purpose register bit to implement it.
The patch adds a workaround for such select input quirk by interpreting
the input_val cell of pin function ID in a different way, so that all
the info that needed for setting up select input bits in general purpose
register could be decoded from there.
*map should be tested for NULL instead of map as kmalloc pointer
is assigned to it. This also fixes a potential null pointer dereference
bug later in the code.
So, I notice that we get a couple of warnings from the pinctrl code:
drivers/pinctrl/pinconf.c: In function 'pinconf_dbg_config_print':
drivers/pinctrl/pinconf.c:433:36: warning: 'configs' may be used uninitialized in this function

drivers/pinctrl/pinconf.c:511:36: warning: 'configs' may be used uninitialized in this function
While the compiler might not be able to work out that "configs" is
safe, the code doesn't lend itself very well to identifying that
fact when reading it either. This can be trivially solved by a slight
restructuring of the code - which also reduces the LOC.

slob: Rework #ifdeffery in slab.h
mm, slab: moved kmem_cache_alloc_node comment to correct place
Now, this uses SLUB pretty much unmodified, but as it is the -rt kernel
with CONFIG_PREEMPT_RT set, spinlocks are mutexes, although they do
disable migration. But the SLUB code is relatively lockless, and the
spin_locks there are raw_spin_locks (not converted to mutexes), thus I
believe this bug can happen in mainline without -rt features. The -rt
patch is just good at triggering mainline bugs ;-)
Anyway, looking at where this crashed, it seems that the page variable
can be NULL when passed to the node_match() function (which does not
check if it is NULL). When this happens we get the above panic.
As page is only used in slab_alloc() to check if the node matches, if
it's NULL I'm assuming that we can say it doesn't and call the
__slab_alloc() code. Is this a correct assumption?

Merge branch 'fixes' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM fixes from Russell King:
"A few fixes for ARM, mostly just one liners with the exception of the
missing section specification. We decided not to rely on .previous to
fix this but to explicitly state the section we want the code to be
in."
* 'fixes' of git://git.linaro.org/people/rmk/linux-arm:
ARM: 7778/1: smp_twd: twd_update_frequency need be run on all online CPUs
ARM: 7782/1: Kconfig: Let ARM_ERRATA_364296 not depend on CONFIG_SMP
ARM: mm: fix boot on SA1110 Assabet

Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:
"MIPS updates:
- All the things that didn't make 3.10.
- Removes the Windriver PPMC platform. Nobody will miss it.
- Remove a workaround from kernel/irq/irqdomain.c which was there
exclusivly for MIPS. Patch by Grant Likely.
- More small improvments for the SEAD 3 platform
- Improvments on the BMIPS / SMP support for the BCM63xx series.
- Various cleanups of dead leftovers.
- Platform support for the Cavium Octeon-based EdgeRouter Lite.
Two large KVM patchsets didn't make it for this pull request because
their respective authors are vacationing"
