507a03c1cb Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux
This includes initial support for the recently published ACPI 5.0 spec.
In particular, support for the "hardware-reduced" bit that eliminates
the dependency on legacy hardware.

APEI has patches resulting from testing on real hardware.

Plus other random fixes.

c130bd6f82 acpi/apei/einj: Add extensions to EINJ from rev 5.0 of acpi spec
ACPI 5.0 provides extensions to the EINJ mechanism to specify the
target for the error injection - by APICID for cpu related errors,
by address for memory related errors, and by segment/bus/device/function
for PCIe related errors. Also extensions for vendor specific error
injections.

7bb0f088f8 [media] DocBook/dvbproperty.xml: Remove DTV_MODULATION from ISDB-T
On ISDB-T, each layer can have its own independent modulation,
applied to the carriers that belong to the segments associated

The ISDB-T differs on its way to implement the hierarchical

FEC codes, it does that by using different layers, each layer
with their groups of segments. So, those parameters don't make sense

   reporting).
 - Memory hotplug support.
 
 Usability improvements:
 - Show the origin of early allocations.
 - Report previously found leaks even if kmemleak has been disabled by

7c7c7f01cc vhost-net: add module alias (v2.1)
By adding some module aliases, programs (or users) won't have to explicitly
call modprobe. Vhost-net will always be available if built into the kernel.
It does require assigning a permanent minor number for depmod to work.

Also:
  - use C99 style initialization.
  - add missing entry in documentation for loop-control

081794564e dma-buf: Documentation update for Kconfig select
As per Linus' comment, dma-buf Kconfig entry shouldn't have an option
text, but should be selected by the subsystems that use it.

Add this information in the documentation as well.

099469502f Merge branch 'akpm' (aka "Andrew's patch-bomb, take two")
Andrew explains:

 - various misc stuff

 - Most of the rest of MM: memcg, threaded hugepages, others.

 - cpumask

 - kexec

 - kdump

 - some direct-io performance tweaking

 - radix-tree optimisations

 - new selftests code

   A note on this: often people will develop a new userspace-visible
   feature and will develop userspace code to exercise/test that
   feature.  Then they merge the patch and the selftest code dies.
   Sometimes we paste it into the changelog.  Sometimes the code gets
   thrown into Documentation/(!).

   This saddens me.  So this patch creates a bare-bones framework which
   will henceforth allow me to ask people to include their test apps in
   the kernel tree so we can keep them alive.  Then when people enhance
   or fix the feature, I can ask them to update the test app too.

   The infrastruture is terribly trivial at present - let's see how it
   evolves.

 - checkpoint/restart feature work.

   A note on this: this is a project by various mad Russians to perform
   c/r mainly from userspace, with various oddball helper code added
   into the kernel where the need is demonstrated.

   So rather than some large central lump of code, what we have is
   little bits and pieces popping up in various places which either
   expose something new or which permit something which is normally
   kernel-private to be modified.

   The overall project is an ongoing thing.  I've judged that the size
   and scope of the thing means that we're more likely to be successful
   with it if we integrate the support into mainline piecemeal rather
   than allowing it all to develop out-of-tree.

   However I'm less confident than the developers that it will all
   eventually work! So what I'm asking them to do is to wrap each piece
   of new code inside CONFIG_CHECKPOINT_RESTORE.  So if it all
   eventually comes to tears and the project as a whole fails, it should
   be a simple matter to go through and delete all trace of it.

This lot pretty much wraps up the -rc1 merge for me.

b3f7f573a2 c/r: procfs: add start_data, end_data, start_brk members to /proc/$pid/stat v4
The mm->start_code/end_code, mm->start_data/end_data, mm->start_brk are
involved into calculation of program text/data segment sizes (which might
be seen in /proc/<pid>/statm) and into brk() call final address.

For restore we need to know all these values.  While
mm->start_code/end_code already present in /proc/$pid/stat, the rest
members are not, so this patch brings them in.

The restore procedure of these members is addressed in another patch using
prctl().

b8f566b04d sysctl: add the kernel.ns_last_pid control
The sysctl works on the current task's pid namespace, getting and setting
its last_pid field.

Writing is allowed for CAP_SYS_ADMIN-capable tasks thus making it possible
to create a task with desired pid value.  This ability is required badly
for the checkpoint/restore in userspace.

This approach suits all the parties for now.
