 "Majority of AIO stuff this cycle. aio-fsync and aio-poll, mostly.

  The only thing I'm holding back for a day or so is Adam's aio ioprio -
  his last-minute fixup is trivial (missing stub in !CONFIG_BLOCK case),
  but let it sit in -next for decency sake..."

eeee3149aa There's been a fair amount of work in the docs tree this time around,
including:
 
  - Extensive RST conversions and organizational work in the
    memory-management docs thanks to Mike Rapoport.
 
  - An update of Documentation/features from Andrea Parri and a script to
    keep it updated.
 
  - Various LICENSES updates from Thomas, along with a script to check SPDX
    tags.
 
  - Work to fix dangling references to documentation files; this involved a
    fair number of one-liner comment changes outside of Documentation/
 
 ...and the usual list of documentation improvements, typo fixes, etc.

f462951e87 docs/admin-guide/mm: add high level concepts overview
The are terms that seem obvious to the mm developers, but may be somewhat
obscure for, say, less involved readers.

The concepts overview can be seen as an "extended glossary" that introduces
such terms to the readers of the kernel documentation.

098afd9817 x86/pci-dma: remove the explicit nodac and allowdac option
This is something drivers should decide (modulo chipset quirks like
for VIA), which as far as I can tell is how things have been handled
for the last 15 years.

Note that we keep the usedac option for now, as it is used in the wild
to override the too generic VIA quirk.

3deb642f0d fs: introduce new ->get_poll_head and ->poll_mask methods
->get_poll_head returns the waitqueue that the poll operation is going
to sleep on.  Note that this means we can only use a single waitqueue
for the poll, unlike some current drivers that use two waitqueues for
different events.  But now that we have keyed wakeups and heavily use
those for poll there aren't that many good reason left to keep the
multiple waitqueues, and if there are any ->poll is still around, the
driver just won't support aio poll.

af8d3c7c00 ppp: remove the PPPIOCDETACH ioctl
The PPPIOCDETACH ioctl effectively tries to "close" the given ppp file
before f_count has reached 0, which is fundamentally a bad idea.  It
does check 'f_count < 2', which excludes concurrent operations on the
file since they would only be possible with a shared fd table, in which
case each fdget() would take a file reference.  However, it fails to
account for the fact that even with 'f_count == 1' the file can still be
linked into epoll instances.  As reported by syzbot, this can trivially
be used to cause a use-after-free.

Yet, the only known user of PPPIOCDETACH is pppd versions older than
ppp-2.4.2, which was released almost 15 years ago (November 2003).
Also, PPPIOCDETACH apparently stopped working reliably at around the
same time, when the f_count check was added to the kernel, e.g. see
https://lkml.org/lkml/2002/12/31/83.  Also, the current 'f_count < 2'
check makes PPPIOCDETACH only work in single-threaded applications; it
always fails if called from a multithreaded application.

All pppd versions released in the last 15 years just close() the file
descriptor instead.

Therefore, instead of hacking around this bug by exporting epoll
internals to modules, and probably missing other related bugs, just
remove the PPPIOCDETACH ioctl and see if anyone actually notices.  Leave
a stub in place that prints a one-time warning and returns EINVAL.

Updated version of the ltc2990 driver which supports all measurement
modes (current, voltage, temperature) available in the chip.

If devicetree is used, the mode must be specified with the property
"lltc,meas-mode". The format and possible values of the property are
described in the binding.

If devicetree is not used, the mode of the chip will not be configured.
Unless the chip is configured by another source, only the internal
temperature and supply voltage will be measured.

203ec2fed1 ARM: SoC fixes for 4.17-rc
A handful of fixes. I've been queuing them up a bit too long so the list
 is longer than it otherwise would have been spread out across a few -rcs.
 
 In general, it's a scattering of fixes across several platforms, nothing
 truly serious enough to point out.
 
 There's a slightly larger batch of them for the Davinci platforms due
 to work to bring them back to life after some time, so there's a handful
 of regressions, some of them going back very far, others more recent.
 
 There's also a few patches fixing DT on Renesas platforms since they
 changed some bindings without remaining backwards compatible, splitting
 up describing LVDS as a proper bridge instead of having it as part of the
 display unit. We could push for them to be backwards compatible with old
 device trees, but it's likely to regress eventually if nobody's actually
 using said compatibility.

633711e828 kvm: rename KVM_HINTS_DEDICATED to KVM_HINTS_REALTIME
KVM_HINTS_DEDICATED seems to be somewhat confusing:

Guest doesn't really care whether it's the only task running on a host
CPU as long as it's not preempted.

And there are more reasons for Guest to be preempted than host CPU
sharing, for example, with memory overcommit it can get preempted on a
memory access, post copy migration can cause preemption, etc.

Let's call it KVM_HINTS_REALTIME which seems to better
match what guests expect.

Also, the flag most be set on all vCPUs - current guests assume this.
Note so in the documentation.

e1b505a603 net: phy: micrel: add 125MHz reference clock workaround
The micrel KSZ9031 phy has a optional clock pin (CLK125_NDO) which can be
used as reference clock for the MAC unit. The clock signal must meet the
RGMII requirements to ensure the correct data transmission between the
MAC and the PHY. The KSZ9031 phy does not fulfill the duty cycle
requirement if the phy is configured as slave. For a complete
describtion look at the errata sheets: DS80000691D or DS80000692D.

The errata sheet recommends to force the phy into master mode whenever
there is a 1000Base-T link-up as work around. Only set the
"micrel,force-master" property if you use the phy reference clock provided
by CLK125_NDO pin as MAC reference clock in your application.

Attenation, this workaround is only usable if the link partner can
be configured to slave mode for 1000Base-T.
