The following PowerPC commit:

  c118baf8 ("arch/powerpc/mm/numa.c: do not allocate bootmem memory for non existing nodes")

avoids allocating bootmem memory for non existent nodes.

But when DEBUG_PER_CPU_MAPS=y is enabled, my powerNV system failed to boot
because in sched_init_numa(), cpumask_or() operation was done on
unallocated nodes.

Fix that by making cpumask_or() operation only on existing nodes.

[ Tested with and w/o DEBUG_PER_CPU_MAPS=y on x86 and PowerPC. ]

Pull i2c updates from Wolfram Sang:
 "Quite some driver updates:
   - piix4 can now handle multiplexed adapters
   - brcmstb, xlr, eg20t, designware drivers support more SoCs
   - emev2 gained i2c slave support
   - img-scb and rcar got bigger refactoring to remove issues
   - lots of common driver updates

  i2c core changes:
   - new quirk flag when an adapter does not support clock stretching,
     so clients can be configured to avoid that if possible
   - added a helper function to retrieve timing parameters from firmware
     (with rcar being the first user)
   - "multi-master" DT binding added so drivers can adapt to this
     setting (like disabling PM to keep arbitration working)
   - RuntimePM for the logical adapter device is now always enabled by
     the core to ensure propagation from childs to the parent (the HW
     device)

Originally we calculated ht_nodeid as "ht_nodeid = apicid -
boot_cpu_id;" so presumably it could be negative.

But after commit:

  01aaea1a ('x86: introduce initial apicid')

we use c->initial_apicid which is an unsigned short and thus always >= 0.

It causes a static checker warning to test for impossible
conditions so let's remove it.

The mfd/s2mpa01.txt duplicates some of the information about bindings
with old mfd/s2mps11.txt. Now common part exists entirely in
mfd/samsung,sec-core.txt so:
 - add company prefix to file name (regulator/samsung,s2mpa01.txt),
 - remove duplicated information,
 - reorganize the contents to match style of

Bindings for Samsung S2M and S5M family PMICs are in mess. They are
spread over different files and subdirectories in a non-consistent way.
The devices and respective drivers for them share a lot in common so
everything could be organized in a more readable way.

Reorganize the S2MPS11/13/14/15 Device Tree bindings to match the
drivers for this family of devices:
 - move mfd/s2mps11.txt to mfd/samsung,sec-core.txt for the main MFD
   driver (common for entire family),
 - split clock block to clock/samsung,s2mps11.txt,
 - split regulator block to regulator/samsung,s2mps11.txt.

As we want gpio_chip .get() calls to be able to return negative
error codes and propagate to drivers, we need to go over all
drivers and make sure their return values are clamped to [0,1].
We do this by using the ret = !!(val) design pattern.
