9ddfa69fb0 doc: add information about max_ptes_none
max_ptes_none specifies how many extra small pages (that are
not already mapped) can be allocated when collapsing a group
of small pages into one large page.

/sys/kernel/mm/transparent_hugepage/khugepaged/max_ptes_none

A higher value leads to use additional memory for programs.
A lower value leads to gain less thp performance. Value of
max_ptes_none can waste cpu time very little, you can
ignore it.

433b89cfb4 Doc/memory-hotplug.txt: corrections and callback function prototype
Documentation/memory-hotplug.txt describes that a callback function can
be added to the notification chain by calling hotplug_memory_notifier().
The function prototype of the callback function is mssing. This missing
information is added by the patch.

The description of the arguments of the callback function is
reworked.

The constants for the event types are corrected.

The possible return values are explained.

09677e0ff8 Documentation/CodingStyle: improve text layout
Try to make coding style documentation look a bit more readable and
consistent with the following:

 - indent every code example in C to first tab-stop;
 - surround every code example with empty lines, both top and bottom;
 - remove empty lines where text looked way too spare;
 - do not indent examples in elisp and kconfig;
 - do not do any non-whitespace changes.

Pull MIPS updates from Ralf Baechle:
 "This is the main pull request for MIPS:

   - a number of fixes that didn't make the 3.19 release.

   - a number of cleanups.

   - preliminary support for Cavium's Octeon 3 SOCs which feature up to
     48 MIPS64 R3 cores with FPU and hardware virtualization.

   - support for MIPS R6 processors.

     Revision 6 of the MIPS architecture is a major revision of the MIPS
     architecture which does away with many of original sins of the
     architecture such as branch delay slots.  This and other changes in
     R6 require major changes throughout the entire MIPS core
     architecture code and make up for the lion share of this pull
     request.

   - finally some preparatory work for eXtendend Physical Address
     support, which allows support of up to 40 bit of physical address
     space on 32 bit processors"

       every CPU architect has to make that mistake, but pee in the snow

18a8d49973 The clock framework changes for 3.20 contain the usual driver additions,
enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based
 devices. Additionaly the framework core underwent a bit of surgery with
 two major changes. The boundary between the clock core and clock
 providers (e.g clock drivers) is now more well defined with dedicated
 provider helper functions. struct clk no longer maps 1:1 with the
 hardware clock but is a true per-user cookie which helps us tracker
 users of hardware clocks and debug bad behavior. The second major change
 is the addition of rate constraints for clocks. Rate ranges are now
 supported which are analogous to the voltage ranges in the regulator
 framework. Unfortunately these changes to the core created some
 breakeage. We think we fixed it all up but for this reason there are
 lots of last minute commits trying to undo the damage.

53861af9a1 OK, this has the big virtio 1.0 implementation, as specified by OASIS.
On top of tht is the major rework of lguest, to use PCI and virtio 1.0, to
 double-check the implementation.
 
 Then comes the inevitable fixes and cleanups from that work.
 
 Thanks,

On some chips, like the TPS386000, the trigger cannot be disabled
and the CPU must keep toggling the line at all times. Add a switch
"always_running" to keep toggling the GPIO line regardless of the
state of the soft part of the watchdog. The "armed" member keeps
track of whether a timeout must also cause a reset.

 other non-GPL projects more easily. There's also been changes to the

878ba61aa9 ARM: SoC platform changes
New and updated SoC support. Also included are some cleanups where the
 platform maintainers hadn't separated cleanups from new developent in
 separate branches.
 
 Some of the larger things worth pointing out:
 
 - A large set of changes from Alexandre Belloni and Nicolas Ferre
   preparing at91 platforms for multiplatform and cleaning up quite a
   bit in the process.
 - Removal of CSR's "Marco" SoC platform that never made it out to the
   market. We love seeing these since it means the vendor published
   support before product was out, which is exactly what we want!
 
 New platforms this release are:
 
 - Conexant Digicolor (CX92755 SoC)
 - Hisilicon HiP01 SoC
 - CSR/sirf Atlas7 SoC
 - ST STiH418 SoC
 - Common code changes for Nvidia Tegra132 (64-bit SoC)
 
 We're seeing more and more platforms having a harder time labelling
 changes as cleanups vs new development -- which is a good sign that
 we've come quite far on the cleanup effort. So over time we might start
 combining the cleanup and new-development branches more.

Merge tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC platform changes from Olof Johansson:
 "New and updated SoC support.  Also included are some cleanups where
  the platform maintainers hadn't separated cleanups from new developent
  in separate branches.

  Some of the larger things worth pointing out:

   - A large set of changes from Alexandre Belloni and Nicolas Ferre
     preparing at91 platforms for multiplatform and cleaning up quite a
     bit in the process.

   - Removal of CSR's "Marco" SoC platform that never made it out to the
     market.  We love seeing these since it means the vendor published
     support before product was out, which is exactly what we want!

  New platforms this release are:

   - Conexant Digicolor (CX92755 SoC)
   - Hisilicon HiP01 SoC
   - CSR/sirf Atlas7 SoC
   - ST STiH418 SoC
   - Common code changes for Nvidia Tegra132 (64-bit SoC)

  We're seeing more and more platforms having a harder time labelling
  changes as cleanups vs new development -- which is a good sign that
  we've come quite far on the cleanup effort.  So over time we might
  start combining the cleanup and new-development branches more"

Add initial support to the Broadcom iProc I2C controller found in the
iProc family of SoCs.

The iProc I2C controller has separate internal TX and RX FIFOs, each has
a size of 64 bytes. The iProc I2C controller supports two bus speeds
including standard mode (100kHz) and fast mode (400kHz)

d92576f116 dax: does not work correctly with virtual aliasing caches
The DAX code accesses the underlying storage through the kernel's linear
mapping, which may not be cache-coherent with user mappings on ARM, MIPS
or SPARC.  Temporarily disable the DAX code until this problem is
resolved.

The original XIP code also had this problem, but it was never noticed.

25726bc157 dax: add dax_zero_page_range
This new function allows us to support hole-punch for DAX files by zeroing
a partial page, as opposed to the dax_truncate_page() function which can
only truncate to the end of the page.  Reimplement dax_truncate_page() to
call dax_zero_page_range().
