Pull powerpc fixes from Michael Ellerman:
 "One notable fix to properly advertise our support for a new firmware
  feature, caused by two series conflicting semantically but not
  textually.

  There's a new ioctl for the new ocxl driver, which is not a fix, but
  needed to complete the userspace API and good to have before the
  driver is in a released kernel.

  Finally three minor selftest fixes, and a fix for intermittent build
  failures for some obscure platforms, caused by a missing make
  dependency.

  Thanks to: Alastair D'Silva, Bharata B Rao, Guenter Roeck"

Some required information is not exposed to userspace currently (eg. the
PASID), pass this information back, along with other information which
is currently communicated via sysfs, which saves some parsing effort in
userspace.

Pull powerpc fixes from Michael Ellerman:

 - Add handling for a missing instruction in our 32-bit BPF JIT so that
   it can be used for seccomp filtering.

 - Add a missing NULL pointer check before a function call in new EEH
   code.

 - Fix an error path in the new ocxl driver to correctly return EFAULT.

 - The support for the new ibm,drc-info device tree property turns out
   to need several fixes, so for now we just stop advertising to
   firmware that we support it until the bugs can be ironed out.

 - One fix for the new drmem code which was incorrectly modifying the
   device tree in place.

 - Finally two fixes for the RFI flush support, so that firmware can
   advertise to us that it should be disabled entirely so as not to
   affect performance.

 "Here are a handful of char/misc driver fixes for 4.16-rc3.

  There are some binder driver fixes to resolve reported issues in
  stress testing the recent binder changes, some extcon driver fixes,
  and a few mei driver fixes and new device ids.

  All of these, with the exception of the mei driver id additions, have
  been in linux-next for a while. I forgot to push out the mei driver id
  additions to kernel.org until today, but all build tests pass with
  them enabled"

This fixes regression introduced by
commit 8d52af6795c0 ("mei: speed up the power down flow")

In mei_cldev_disable during device power down flow, such as
suspend or system power off, it jumps over disconnecting function
to speed up the power down process, however, because the client is
unlinked from the file_list (mei_cl_unlink) mei_cl_set_disconnected
is not called from mei_cl_all_disconnect leaving resource leaking.
The most visible is reference counter on underlying HW module is
not decreased preventing to remove modules after suspend/resume cycles.

 "A larger batch of fixes than we'd like. Roughly 1/3 fixes for new
  code, 1/3 fixes for stable and 1/3 minor things.

  There's four commits fixing bugs when using 16GB huge pages on hash,
  caused by some of the preparatory changes for pkeys.

  Two fixes for bugs in the enhanced IRQ soft masking for local_t, one
  of which broke KVM in some circumstances.

  Four fixes for Power9. The most bizarre being a bug where futexes
  stopped working because a NULL pointer dereference didn't trap during
  early boot (it aliased the kernel mapping). A fix for memory hotplug
  when using the Radix MMU, and a fix for live migration of guests using
  the Radix MMU.

  Two fixes for hotplug on pseries machines. One where we weren't
  correctly updating NUMA info when CPUs are added and removed. And the
  other fixes crashes/hangs seen when doing memory hot remove during
  boot, which is apparently a thing people do.

  Finally a handful of build fixes for obscure configs and other minor
  fixes.

This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:

    for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
        L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
        for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
    done

with de-mangling cleanups yet to come.

NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do.  But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.

The next patch from Al will sort out the final differences, and we
should be all done.
