After patch "of/platform: Add common method to populate default bus",
it is possible for arch code to remove unnecessary callers of
of_platform_populate with default match table.Move of_clk_init() into time_init(), then drop xtensa_device_probe() fully.

The arch code calls of_platform_populate() with default match table
when it wants to populate default bus.This patch introduce a new of_platform_default_populate_init() and make it
arch_initcall_sync(it should be later than some iommu configration, eg,
of_iommu_init() and swiotlb_late_init in arm64), then we can finish above
job in common method.In order to avoid the default bus being populated twice, simply checking
the flag of bus node whether has be set OF_POPULATED_BUS or not.After that, we can safely remove the caller in arch code.
Btw, add debug print in of_platform_populate(), and use __func__ to
print function's name of of_platform_bus_create().Cc: Rob Herring

The of_iommu_init() is called multiple times by arch code,
make it postcore_initcall_sync, then we can drop relevant
calls fully.Note, the IOMMUs should have a chance to perform some basic
initialisation before we start adding masters to them. So
postcore_initcall_sync is good choice, it ensures of_iommu_init()
called before of_platform_populate.Acked-by: Rich Felker

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

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"* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:

Merge filesystem stacking fixes from Jann Horn.
* emailed patches from Jann Horn :
sched: panic on corrupted stack end
ecryptfs: forbid opening files without mmap handler
proc: prevent stacking filesystems on top -
Until now, hitting this BUG_ON caused a recursive oops (because oops
handling involves do_exit(), which calls into the scheduler, which in
turn raises an oops), which caused stuff below the stack to be
overwritten until a panic happened (e.g. via an oops in interrupt
context, caused by the overwritten CPU index in the thread_info).Just panic directly.

Signed-off-by: Linus Torvalds -
This prevents stacking filesystems (ecryptfs and overlayfs) from using
procfs as lower filesystem. There is too much magic going on inside
procfs, and there is no good reason to stack stuff on top of procfs.(For example, procfs does access checks in VFS open handlers, and
ecryptfs by design calls open handlers from a kernel thread that doesn't
drop privileges or so.)Signed-off-by: Jann Horn
