  Subsystem:

   - expose non volatile RAM using nvmem instead of open coding in many

     not break existing users.

   - rtctest can now test for cutoff dates, showing when an RTC will
     start failing to properly save time and date.

   - new RTC registration functions to remove race conditions in drivers

  Newly supported RTCs:

   - Broadcom STB wake-timer

   - STMicroelectronics STM32H7

So far Linux supported only two levels of MTD devices so we didn't need
a very precise description for this sysfs file. With commit
97519dc5

 ("mtd: partitions: add support for subpartitions") there
is support for a tree structure so we should have more precise
description. Using "parent" and "flash device" makes it more accurate.

I made the mistake of upgrading my desktop to the new Fedora 26 that
comes with gcc-7.1.1.

There's nothing wrong per se that I've noticed, but I now have 1500
lines of warnings, mostly from the new format-truncation warning
triggering all over the tree.

We use 'snprintf()' and friends in a lot of places, and often know that
the numbers are fairly small (ie a controller index or similar), but gcc
doesn't know that, and sees an 'int', and thinks that it could be some
huge number.  And then complains when our buffers are not able to fit
the name for the ten millionth controller.

These warnings aren't necessarily bad per se, and we probably want to
look through them subsystem by subsystem, but at least during the merge
window they just mean that I can't even see if somebody is introducing
any *real* problems when I pull.

So warnings disabled for now.

  module: Add module name to modinfo
  module: Pass struct load_info into symbol checks

Currently the writeback statistics code uses a percpu counters to hold
various statistics.  Furthermore we have 2 families of functions - those
which disable local irq and those which doesn't and whose names begin
with double underscore.  However, they both end up calling
__add_wb_stats which in turn calls percpu_counter_add_batch which is
already irq-safe.

Exploiting this fact allows to eliminated the __wb_* functions since
they don't add any further protection than we already have.
Furthermore, refactor the wb_* function to call __add_wb_stat directly
without the irq-disabling dance.  This will likely result in better
runtime of code which deals with modifying the stat counters.

While at it also document why percpu_counter_add_batch is in fact
preempt and irq-safe since at least 3 people got confused.

Make the code like the rest of the kernel.

But there is an oddity here because the inline should probably be removed.

It's an extern function in intelfb.h and it is used in intelfbdrv.c and
intelfbhw.c.

The inline is kept here as I suppose it's possible for some compiler to
make the uses inline in intelfbdrv and and also create an external
function for intelfbhw.

Convert 'u8 inline' to 'inline u8' to be the same style used by the rest
of the kernel.

Miscellanea:

jornada_ssp_reverse is an odd function.
It is declared inline but is also EXPORT_SYMBOL.
It is also apparently only used by jornada720_ssp.c
Likely the EXPORT_SYMBOL could be removed and the function
converted to static.

The addition of static and removal of EXPORT_SYMBOL was not done.

is better written

Page migration (for memory hotplug, soft_offline_page or mbind) needs to
allocate a new memory.  This can trigger an oom killer if the target
memory is depleated.  Although quite unlikely, still possible,
especially for the memory hotplug (offlining of memoery).

Up to now we didn't really have reasonable means to back off.
__GFP_NORETRY can fail just too easily and __GFP_THISNODE sticks to a
single node and that is not suitable for all callers.

But now that we have __GFP_RETRY_MAYFAIL we should use it.  It is
preferable to fail the migration than disrupt the system by killing some
processes.

Commit 24f8e00a ("drm/i915: Prefer to report ENOMEM rather than
incur the oom for gfx allocations") has tried to remove disruptive OOM
killer because the userspace should be able to cope with allocation
failures.

At the time only __GFP_NORETRY could achieve that and it turned out that
this would fail the allocations just too easily.  So "drm/i915: Remove
__GFP_NORETRY from our buffer allocator" removed it and hoped for a
better solution.  __GFP_RETRY_MAYFAIL is that solution.  It will keep
retrying the allocation until there is no more progress and we would go
OOM.  Instead we fail the allocation and let the caller to deal with it.
