The VFS timestamps are all 64-bit now, the only missing piece for hpfs
is the internal conversion function.  One interesting bit about hpfs is
that it can already deal with moving the 136 year window of its
timestamps to support a much wider range than other file systems with
32-bit timestamps.  It also treats the timestamps as 'unsigned' on
64-bit architectures (but signed on 32-bit, because time_t always around
to negative numbers in 2038).

Changing the conversion to use time64_t makes 32-bit architectures
behave the same way as 64-bit.  For completeness, this also adds a
clamp_t call for each conversion, so we don't wrap the timestamps but
instead stay within the [0..U32_MAX] range of the on-disk timestamps.

Now that the VFS has been converted from timespec to timespec64
timestamps, only the conversion to/from ntfs timestamps uses 32-bit
seconds.

This changes that last missing piece to get the ntfs implementation
y2038 safe on 32-bit architectures.

get_seconds() is deprecated because of the 32-bit overflow and will be
removed.  All callers in ufs also truncate to a 32-bit number, so
nothing changes during the conversion, but this should be harmless as
the superblock and cylinder group timestamps are not visible to user
space, except for checking the fs-dirty state, wich works fine across
the overflow.

This moves the call to get_seconds() into a new inline function, with a
comment explaining the constraints, while converting it to
ktime_get_real_seconds().

32-bit CLOCK_REALTIME timestamps overflow in year 2038, so all such
interfaces are deprecated now.  For the FW_CDEV_IOC_GET_CYCLE_TIMER2
ioctl, we already support 64-bit timestamps, but the implementation
still uses timespec.

This changes the code to use timespec64 instead with the appropriate
accessor functions.

This patch is reworked from an earlier patch that Dan has posted:
https://patchwork.kernel.org/patch/10131727/

VM_MIXEDMAP is used by dax to direct mm paths like vm_normal_page() that
the memory page it is dealing with is not typical memory from the linear
map.  The get_user_pages_fast() path, since it does not resolve the vma,
is already using {pte,pmd}_devmap() as a stand-in for VM_MIXEDMAP, so we
use that as a VM_MIXEDMAP replacement in some locations.  In the cases
where there is no pte to consult we fallback to using vma_is_dax() to
detect the VM_MIXEDMAP special case.

Now that we have explicit driver pfn_t-flag opt-in/opt-out for
get_user_pages() support for DAX we can stop setting VM_MIXEDMAP.  This
also means we no longer need to worry about safely manipulating vm_flags
in a future where we support dynamically changing the dax mode of a
file.

DAX should also now be supported with madvise_behavior(), vma_merge(),
and copy_page_range().

This patch has been tested against ndctl unit test.  It has also been
tested against xfstests commit: 625515d using fake pmem created by
memmap and no additional issues have been observed.

 "The new and exciting feature this time around is in the clk core.
  We've added duty cycle support to the clk API so that clk signal duty

  support for this, but I expect there will be more to come in the
  future.

  Outside of the core, we have the usual pile of clk driver updates and
  additions. The Amlogic meson driver got the most lines in the diffstat
  this time around because it added support for a whole bunch of
  hardware and duty cycle configuration. After that the Rockchip PX30,
  Qualcomm SDM845, and Renesas SoC drivers fill in a majority of the
  diff. We're left with the collection of non-critical fixes after that.

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v4.19 kernel cycle.

  I don't know if anything in particular stands out. Maybe the Aspeed
  coprocessor thing from Benji: Aspeed is doing baseboard management
  chips (BMC's) for servers etc.

  These Aspeed's are ARM processors that exist inside (I guess) Intel
  servers, and they are moving forward to using mainline Linux in those.
  This is one of the pieces of the puzzle to achive that. They are doing
  OpenBMC, it's pretty cool: https://lwn.net/Articles/683320/

  Summary:

  Core changes:

   - Add a new API for explicitly naming GPIO consumers, when needed.

   - Don't let userspace set values on input lines. While we do not
     think anyone would do this crazy thing we better plug the hole
     before someone uses it and think it's a nifty feature.

   - Avoid calling chip->request() for unused GPIOs.

Commit c647f806 ("ALSA: hda - Allow multiple ADCs for mic mute LED
controls") changed the return value of the snd_hda_gen_add_micmute_led()
without actually updating the callers.

Admittedly, almost no callers actually cared about the return value.
But one call site very much did: the Dell wmi code.  It would see the
registration return zero, which _used_ to mean "failed" but now means
"success", and clear the dell_micmute_led_set_func pointer.

End result: the successful registration would end up calling the Dell
code that thought it had all failed, and call through a NULL pointer.

To make matters worse, it ends up being a tail-call, and with the
retpoline sequence you don't even see the caller (dell_micmute_update())
in the stack trace, so the error ended up way less obvious than it
should have been.
