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.

The DEFINE_SHOW_ATTRIBUTE() helper macro would be useful for current
users, which are many of them, and for new comers to decrease code
duplication.

Pull regmap updates from Mark Brown:
 "A very busy release for regmap, all fairly specialist stuff but
  useful:

   - Support for disabling locking from Bartosz Golaszewski, allowing
     users that handle their own locking to save some overhead.

   - Support for hwspinlocks in syscons in MFD from Baolin Wang, this is
     going through the regmap tree since the first users turned up some
     some cases that needed interface tweaks with 0 being used as a
     syscon identifier.

   - Support for devices with no read or write flag from Andrew F.
     Davis.

   - Basic support for devices on SoundWire buses from Vinod Koul"

Some system control registers need hardware spinlock to synchronize
between the multiple subsystems, so we should add hardware spinlock
support for syscon.

Make the intel-lpss driver set DPM_FLAG_SMART_SUSPEND for its
devices which will allow them to stay in runtime suspend during
system suspend unless they need to be reconfigured for some reason.

Also make it avoid resuming its child devices if they have
DPM_FLAG_SMART_SUSPEND set to allow them to remain in runtime
suspend during system suspend.
