45624ac389 sh: remove arch-specific localtimer and use generic one
The code being removed was copied from arm, where the corresponding
code was removed in 2013. The only functional change should be that
the rating of the dummy local timer changes from 400 to 100.

3623d13821 sh: provide unified syscall trap compatible with all SH models
Historically SH-2 Linux (and originally uClinux) used a syscall
calling convention incompatible with the established SH-3/4 Linux ABI.
This choice was made because the trap range used by the existing ABI,
0x10-0x17, overlaps with the hardware exception/interrupt trap range
reserved by SH-2, and in particular, with the SH-2A divide-by-zero and
division-overflow exceptions.

Despite the documented syscall convention using the low bits of the
trap number to signal the number of arguments the kernel should
expect, no version of the kernel has ever used this information, nor
is it useful; all of the registers need to be saved anyway. Therefore,
it is possible to pick a new trap number, 0x1f, that is both supported
by all existing SH-3/4 kernels and unassigned as a hardware trap in
the SH-2 range. This makes it possible to produce SH-2 application
binaries that are forwards-compatible with running on SH-3/4 kernels
and to treat SH as a unified platform with varying ISA support levels
rather than multiple gratuitously-incompatible platforms.

This patch adjusts the range checking SH-2 and SH-2A kernels make for
the syscall trap to accept the range 0x1f-0x2f rather than just
0x20-0x2f. As a result, trap 0x1f now acts as a syscall for all SH
models.

ea17c9d868 sh: Use generic clkdev.h header
The generic header file is almost equivalent to the SH one. The
only difference is that the SH one supports allocating clkdev
lookups early using bootmem allocators instead of the slabs. From
what I can tell using visual inspection, the slab is initialized
before any clkdev allocation is made under arch/sh. So let's
remove the arch specific clkdev.h header and use the generic one
instead.

b5b131c747 dmaengine updates for 4.6
This is smallish update with minor changes to core and new driver and usual
 updates. Nothing super exciting here..
 
 - We have made slave address as physical to enable driver to do the mapping.
 - We now expose the maxburst for slave dma as new capability so clients can
   know this and program accordingly
 - addition of device synchronize callbacks on omap and edma.
 - pl330 updates to support DMAFLUSHP for Rockchip platforms.
 - Updates and improved sg handling in Xilinx VDMA driver.
 - New hidma qualcomm dma driver, though some bits are still in progress

a6ab1e8126 sunrpc/cache: drop reference when sunrpc_cache_pipe_upcall() detects a race
sunrpc_cache_pipe_upcall() can detect a race if CACHE_PENDING is no longer
set.  In this case it aborts the queuing of the upcall.
However it has already taken a new counted reference on "h" and
doesn't "put" it, even though it frees the data structure holding the reference.

So let's delay the "cache_get" until we know we need it.

222bde0388 ALSA: hda - Fix mutex deadlock at HDMI/DP hotplug
The recent change in HD-audio HDMI/DP codec driver for allowing the
dynamic PCM binding introduced a new spec->pcm_mutex.  One of the
protected area by this mutex is hdmi_present_sense().  As reported by
Intel CI tests, unfortunately, the new mutex causes a deadlock when
the hotplug/unplug is triggered during the codec is in runtime
suspend.  The buggy code path is like the following:

  hdmi_unsol_event() -> ...
    -> hdmi_present_sense()
==>     ** here taking pcm_mutex
      -> hdmi_present_sense_via_verbs()
        -> snd_hda_power_up_pm() -> ... (runtime resume calls)
          -> generic_hdmi_resume()
            -> hdmi_present_sense()
==>           ** here taking pcm_mutex again!

As we can see here, the problem is that the mutex is taken before
snd_hda_power_up_pm() call that triggers the runtime resume.  That is,
the obvious solution is to move the power up/down call outside the
mutex; it is exactly what this patch provides.

The patch also clarifies why this bug wasn't caught beforehand.  We
used to have the i915 audio component for hotplug for all Intel chips,
and in that code path, there is no power up required but the
information is taken directly from the graphics side.  However, we
recently switched back to the old method for some old Intel chips due
to regressions, and now the deadlock issue is surfaced.

Fixes: a76056f2e5 ('ALSA: hda - hdmi dynamically bind PCM to pin when monitor hotplug')

83c742c344 mmc: block: fix ABI regression of mmc_blk_ioctl
If mmc_blk_ioctl returns -EINVAL, blkdev_ioctl continues to
work without returning err to user-space. But now we check
CAP_SYS_RAWIO firstly, so we return -EPERM to blkdev_ioctl,
which make blkdev_ioctl return -EPERM to user-space directly.
So this will break all the ioctl with BLKROSET. Now we find
Android-adb suffer it for the following log:

remount of /system failed;
couldn't make block device writable: Operation not permitted
openat(AT_FDCWD, "/dev/block/platform/ff420000.dwmmc/by-name/system", O_RDONLY) = 3
ioctl(3, BLKROSET, 0)  = -1 EPERM (Operation not permitted)

9951362479 mmc: sdhci: Fix override of timeout clk wrt max_busy_timeout
Normally the timeout clock frequency is read from the capabilities
register.  It is also possible to set the value prior to calling
sdhci_add_host() in which case that value will override the
capabilities register value.  However that was being done after
calculating max_busy_timeout so that max_busy_timeout was being
calculated using the wrong value of timeout_clk.

Fix that by moving the override before max_busy_timeout is
calculated.

The result is that the max_busy_timeout and max_discard
increase for BSW devices so that, for example, the time for
mkfs.ext4 on a 64GB eMMC drops from about 1 minute 40 seconds
to about 20 seconds.

Note, in the future, the capabilities setting will be tidied up
and this override won't be used anymore.  However this fix is
needed for stable.

fac49ce575 mmc: mediatek: Use mmc_regulator_set_vqmmc in start_signal_voltage_switch
We've introduced a new helper in the MMC core:
mmc_regulator_set_vqmmc().  Let's use this in mtk-sd.  Using this new
helper has some advantages:

    1. We get the mmc_regulator_set_vqmmc() behavior of trying to match
       VQMMC and VMMC when the signal voltage is 3.3V.  This ensures max
       compatibility.

    2. We get rid of a few more warnings when probing unsupported
       voltages.

    3. We get rid of some non-mediatek specific code in mtk-sd.

That's what happens on eth0 up:
  --------------------------->8------------------------
| libphy: PHY stmmac-0:ffffffff not found
| eth0: Could not attach to PHY
| stmmac_open: Cannot attach to PHY (error: -19)
  --------------------------->8------------------------

Simplest solution is to add PHY description in board's .dts.
And so we do here.
