ea01a18494 autofs races
* make autofs4_expire_indirect() skip the dentries being in process of
expiry
* do *not* mess with list_move(); making sure that dentry with
AUTOFS_INF_EXPIRING are not picked for expiry is enough.
* do not remove NO_RCU when we set EXPIRING, don't bother with smp_mb()
there.  Clear it at the same time we clear EXPIRING.  Makes a bunch of
tests simpler.
* rename NO_RCU to WANT_EXPIRE, which is what it really is.

f83d31635c clk: imx: fix pll clock parents
pllx_bypass_src mux shouldn't be the parent of pllx clock
since it's only valid when when pllx BYPASS bit is set.
Thus it is actually one parent of pllx_bypass only.

Instead, pllx parent should be fixed to osc according to
reference manual.
Other plls have the same issue.

e.g. before fix, the pll tree is:
osc                                      6            6    24000000          0 0
   pll1_bypass_src                       0            0    24000000          0 0
      pll1                               0            0   792000000          0 0
         pll1_bypass                     0            0   792000000          0 0
            pll1_sys                     0            0   792000000          0 0

After the fix, it's:
osc                                      6            6    24000000          0 0
   pll1                                  0            0   792000000          0 0
      pll1_bypass                        0            0   792000000          0 0
         pll1_sys                        0            0   792000000          0 0

2938090556 ARM: imx6: disable deeper idle states when FEC is active w/o HW workaround
The i.MX6 Q/DL has an erratum (ERR006687) that prevents the FEC from
waking the CPUs when they are in wait(unclocked) state. As the hardware
workaround isn't applicable to all boards, disable the deeper idle state
when the workaround isn't present and the FEC is in use.

This allows to safely run a kernel with CPUidle enabled on all i.MX6
boards.

ba7f4f557e clk: imx: correct AV PLL rate formula
The audio/video PLL's rate calculation is as below in RM:

Fref * (DIV_SELECT + NUM / DENOM), in origin clk-pllv3's
code, below code is used:

(parent_rate * div) + ((parent_rate / mfd) * mfn

as it does NOT consider the float data using div, so below
formula should be used as a decent method:

(parent_rate * div) + ((parent_rate * mfn) / mfd)

and we also need to consider parent_rate * mfd may overflow
a 32 bit value, 64 bit value should be used.

After updating this formula, the dram PLL's rate is
1066MHz, which is correct, while the old formula gets
1056MHz.

[Aisheng: fix clk_pllv3_av_round_rate too]

9ef3c51121 mailbox: mailbox-test: set tdev->signal to NULL after freeing
tdev->signal is not set NULL after it's freed. This will cause random
exceptions when the stale pointer is accessed after tdev->signal is
freed. Also, since tdev->signal allocation is skipped the next time
it's written, this leads to continuous fault finally leading to the
total death of the system.

   - Plug fix from Omar, fixing up a case of code being switched between
     two functions.

   - A missing bio_put() for the new discard callers of
     submit_bio_wait(), fixing a regression causing a leak of the bio.
     From Shaun.

   - Improve dirty limit calculation precision in the writeback code,
     fixing a case where setting a limit lower than 1% of memory would
     end up being zero.  From Tejun"

  xen-blkfront: fix resume issues after a migration
  xen-blkfront: don't call talk_to_blkback when already connected to blkback
  nbd: pass the nbd pointer for flags debugfs
  block: missing bio_put following submit_bio_wait

3a7c114d35 GPIO fixes for the v4.7 series:

 - Fix unaligned reference counters: we were ending on +3 after

   get_device(), and call cdev_del() followed by device_del()
   in gpiochip_remove() instead and the count goes to zero and
   calls the release() function properly.
 
 - Fix a compile warning due to a missing #include in the
   OF/device tree portions.
 
 - Select ANON_INODES for GPIOLIB, we're using that for our
   character device. Some randconfig tests disclosed the
   problem.
 
 - Make sure the Zynq driver clock runs also without CONFIG_PM
   enabled
 
 - Fix an off-by-one error in the 104-DIO-48E driver

Merge tag 'gpio-v4.7-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO fixes from Linus Walleij:
 "A new bunch of GPIO fixes for v4.7.

  This time I am very grateful that Ricardo Ribalda Delgado went in and
  fixed my stupid refcounting mistakes in the removal path for GPIO
  chips.  I had a feeling something was wrong here and so it was.  It
  exploded on OMAP and it fixes their problem.  Now it should be (more)
  solid.

  The rest i compilation, Kconfig and driver fixes.  Some tagged for
  stable.

  Summary:

   - Fix a NULL pointer dereference when we are searching the GPIO
     device list but one of the devices have been removed (struct
     gpio_chip pointer is NULL).

   - Fix unaligned reference counters: we were ending on +3 after all
     said and done.  It should be 0.  Remove an extraneous get_device(),
     and call cdev_del() followed by device_del() in gpiochip_remove()
     instead and the count goes to zero and calls the release() function
     properly.

   - Fix a compile warning due to a missing #include in the OF/device
     tree portions.

   - Select ANON_INODES for GPIOLIB, we're using that for our character
     device.  Some randconfig tests disclosed the problem.

   - Make sure the Zynq driver clock runs also without CONFIG_PM enabled

   - Fix an off-by-one error in the 104-DIO-48E driver

   - Fix warnings in bcm_kona_gpio_reset()"

In IPv6 the ToS values are part of the flowlabel in flowi6 and get

the flowlabel before the routing lookup.

703b5faf22 fs/dcache.c: Save one 32-bit multiply in dcache lookup
Noe that we're mixing in the parent pointer earlier, we
don't need to use hash_32() to mix its bits.  Instead, we can
just take the msbits of the hash value directly.

For those applications which use the partial_name_hash(),
move the multiply to end_name_hash.

45b00c94be SCSI fixes on 20160611
Two current fixes: one affects Qemu CD ROM emulation, which stopped
 working after the updates in SCSI to require VPD pages from all
 conformant devices.  Fix temporarily by blacklisting Qemu (we can
 relax later when they come into compliance).  The other is a fix to
 the optimal transfer size.  We set up a minefield for ourselves by
 being confused about whether the limits are in bytes or sectors (SCSI
 optimal is in blocks and the queue parameter is in bytes).  This tries
 to fix the problem (wrong setting for queue limits max_sectors) and
 make the problem more obvious by introducing a wrapper function.
