Merge tag 'imx-fixes-4.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into fixes

Merge "The i.MX fixes for 4.1, 2nd round" from Shawn Guo:

 - Fix i.MX27 FEC register map which overlaps the SCC (Security
   Controller) register space.
 - Fix i.MX27 DTB build rule which was wrongly controlled by i.MX31
   option.

  ARM: dts: fix imx27 dtb build rule
  ARM: dts: imx27: only map 4 Kbyte for fec registers

The i.MX27 dtb build should be controlled by CONFIG_SOC_IMX27 rather
than CONFIG_SOC_IMX31.

Two watchdog changes that came through different trees had a non
conflicting conflict, that is, one changed the semantics of a variable
but no actual code conflict happened. So the merge appeared fine, but
the resulting code did not behave as expected.

Commit 195daf66 ("watchdog: enable the new user interface of the
watchdog mechanism") changes the semantics of watchdog_user_enabled,
which thereafter is only used by the functions introduced by
b3738d29 ("watchdog: Add watchdog enable/disable all functions").

There further appears to be a distinct lack of serialization between
setting and using watchdog_enabled, so perhaps we should wrap the
{en,dis}able_all() things in watchdog_proc_mutex.

This patch fixes a s2r failure reported by Michal; which I cannot
readily explain. But this does make the code internally consistent
again.

In commit 8ff16cf7 ("Documentation: devicetree: m25p80: add "nor-jedec"
binding"), we added a generic "nor-jedec" binding to catch all
mostly-compatible SPI NOR flash which can be detected via the READ ID
opcode (0x9F). This was discussed and reviewed at the time, however
objections have come up since then as part of this discussion:

  http://lkml.kernel.org/g/20150511224646.GJ32500@ld-irv-0074

It seems the parties involved agree that "jedec,spi-nor" does a better
job of capturing the fact that this is SPI-specific, not just any NOR
flash.

This binding was only merged for v4.1-rc1, so it's still OK to change
the naming.

At the same time, let's move the documentation to a better name.

Next up: stop referring to code (drivers/mtd/devices/m25p80.c) from the
documentation.

Pull ACPI fixes from Rafael Wysocki:
 "Two fixes here, one revert of a recent ACPICA commit that broke audio
  support on one Dell machine and a fix for a long-standing issue that
  may cause systems to break randomly during boot.

  Specifics:

   - The recent ACPICA commit that set the ACPI _REV return value to 2
     (which is the value always used by Windows and now mandated by the
     spec too) in order to prevent the firmware people from using it to
     play tricks with us caused a serious audio regression to happen on
     Dell XPS 13 (the AML on that machine uses the _REV return value to
     decide how to expose audio to the OS and does that to hide the lack
     of proper support for its I2S audio in Linux), so revert that
     commit for now and we'll revisit the issue in the next cycle.

   - Ensure that the ordering of acpi_reserve_resources() with respect
     to the rest of the ACPI initialization sequence will always be the
     same, or the IO or memory region occupied by the ACPI fixed
     registers may be assigned to a PCI host bridge as a result of a

NUMA balancing is meant to be disabled by default on UMA machines but
the check is using nr_node_ids (highest node) instead of
num_online_nodes (online nodes).

The consequences are that a UMA machine with a node ID of 1 or higher
will enable NUMA balancing.  This will incur useless overhead due to
minor faults with the impact depending on the workload.  These are the
impact on the stats when running a kernel build on a single node machine
whose node ID happened to be 1:

  			       vanilla     patched
  NUMA base PTE updates          5113158           0
