Linus Torvalds a9a08845e9 vfs: do bulk POLL* -> EPOLL* replacement
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.

Linus Torvalds a051c14b8d More power management updates for v4.16-rc1
- Drop the at32ap-cpufreq driver which is useless after the
    removal of the corresponding arch (Corentin LABBE).
 
  - Fix a regression from the 4.14 cycle in the APM idle driver by
    making it initialize the polling state properly (Rafael Wysocki).
 
  - Fix a crash on failing system suspend due to a missing check in
    the cpufreq core (Bo Yan).
 
  - Make the intel_pstate driver initialize the hardware-managed
    P-state control (HWP) feature on CPU0 upon resume from system
    suspend if HWP had been enabled before the system was suspended
    (Chen Yu).
 
  - Fix up the SCPI cpufreq driver after recent changes (Sudeep Holla,
    Wei Yongjun).
 
  - Avoid pointer subtractions during frequency table walks in cpufreq
    (Dominik Brodowski).
 
  - Avoid the check for ProcFeedback in ST/CZ in the cpufreq driver
    for AMD processors and add a MODULE_ALIAS for cpufreq on ARM IMX
    (Akshu Agrawal, Nicolas Chauvet).
 
  - Fix the prototype of swsusp_arch_resume() on x86 (Arnd Bergmann).
 
  - Fix up the parsing of power domains DT data (Ulf Hansson).

Linus Torvalds 5d8515bc23 Staging/IIO patches for 4.16-rc1
Here is the big Staging and IIO driver patches for 4.16-rc1.
 
 There is the normal amount of new IIO drivers added, like all releases.
 
 The networking IPX and the ncpfs filesystem are moved into the staging
 tree, as they are on their way out of the kernel due to lack of use
 anymore.
 
 The visorbus subsystem finall has started moving out of the staging tree
 to the "real" part of the kernel, and the most and fsl-mc codebases are
 almost ready to move out, that will probably happen for 4.17-rc1 if all
 goes well.
 
 Other than that, there is a bunch of license header cleanups in the
 tree, along with the normal amount of coding style churn that we all
 know and love for this codebase.  I also got frustrated at the
 Meltdown/Spectre mess and took it out on the dgnc tty driver, deleting
 huge chunks of it that were never even being used.
 
 Full details of everything is in the shortlog.
 
 All of these patches have been in linux-next for a while with no
 reported issues.

Kees Cook 841b86f328 treewide: Remove TIMER_FUNC_TYPE and TIMER_DATA_TYPE casts
With all callbacks converted, and the timer callback prototype
switched over, the TIMER_FUNC_TYPE cast is no longer needed,
so remove it. Conversion was done with the following scripts:

    perl -pi -e 's|\(TIMER_FUNC_TYPE\)||g' \
        $(git grep TIMER_FUNC_TYPE | cut -d: -f1 | sort -u)

    perl -pi -e 's|\(TIMER_DATA_TYPE\)||g' \

Greg KH 0da93d2ebb staging: irda: fix init level for irda core
When moving the IRDA code out of net/ into drivers/staging/irda/net, the
link order changes when IRDA is built into the kernel.  That causes a
kernel crash at boot time as netfilter isn't initialized yet.

To fix this, move the init call level of the irda core to be
device_initcall() as the link order keeps this being initialized at the
correct time.
