Commit ddd0ce87bfde ("mips: Remove unnecessary of_platform_populate with
default match table") dropped the include of linux/clk-provider.h from
arch/mips/ath79/setup.c. This results in the following build error.
arch/mips/ath79/setup.c: In function 'ath79_of_plat_time_init':
arch/mips/ath79/setup.c:232:2: error:
implicit declaration of function 'of_clk_init'

Replace the non-standard vendor prefix stm with st for
STMicroelectronics. The drivers do not specify the vendor prefixes
since the I2C Core strips them away from the DT provided compatible
string. Therefore, changing existing device trees does not have any
impact on device detection.

The documentation currently uses the non-standard vendor prefix stm
and st-micro for STMicroelectronics. The drivers do not specify the
vendor prefixes since the I2C Core strips them away from the DT
provided compatible string. Therefor, changing documentation and
existing device trees does not have any impact on device detection.

Determining which kernel config options need to be enabled for a
given devicetree can be a painful process. Create a new tool to
find the drivers that may match a devicetree node compatible,
find the kernel config options that enable the driver, and
optionally report whether the kernel config option is enabled.

Fix a memory leak resulting from memory allocation in safe_name().
This patch fixes all call sites of safe_name().
Mathieu Malaterre reported the memory leak on boot:
On my PowerMac device-tree would generate a duplicate name:
[ 0.023043] device-tree: Duplicate name in PowerPC,G4@0, renamed to "l2-cache#1"
in this case a newly allocated name is generated by `safe_name`. However
in this case it is never deallocated.
The bug was found using kmemleak reported as:

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().

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.

"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

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.

* emailed patches from Jann Horn <[email protected]>:
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.

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.)
