Currently, same stm32f429-pinctrl driver is used for stm32f429 and
stm32f469. As pin map is different between those 2 MCUs,
a stm32f469-pinctrl driver has been recently added.
This patch
 -allows to use stm32f469-pinctrl driver for stm32f469 boards
 -reworks stm32 devicetree files to fit with stm32f429 / stm32f469

In the same time it fixes an issue when only MACH_STM32F469 flag is
selected in menuconfig.

To declare gpio interrupt line for STMPE1600, 2 possibilities are offered:
-use gpio binding (and then the gpiolib interface inside driver)
-use interrupt binding as each gpio-controller are also interrupt controller
 on stm32f429.

In STMPE 1600 node both (gpio and interrupt) bindings are defined.
This patch fixes this issue and use only interrupt binding.

Adding the operating points on rk3368 like they were did not end up well
for the boards as all of them are missing their cpu supplies, the OPPs
actually need to follow the <target min max> format as the regulator is
shared between both clusters and the one rk3368 board I have, somehow also
doesn't like the higher opps at all - all of which I only realized after
I brought my rk3368 board online again, after its bootloader broke.
So we revert that OPP addition for now.

And also two fixes for the mipi dsi controller on rk3399, which was
referencing a clock to high up in the clock-tree so that an intermediate
gate could be disabled inadvertently and also needs a clock for its area
in the general register files of the rk3399 soc.

Pull timer fixes from Thomas Gleixner:
 "This adds a new timer wheel function which is required for the
  conversion of the timer callback function from the 'unsigned long
  data' argument to 'struct timer_list *timer'. This conversion has two
  benefits:

   1) It makes struct timer_list smaller

   2) Many callers hand in a pointer to the timer or to the structure
      containing the timer, which happens via type casting both at setup
      and in the callback. This change gets rid of the typecasts.

  Once the conversion is complete, which is planned for 4.15, the old
  setup function and the intermediate typecast in the new setup function
  go away along with the data field in struct timer_list.

  Merging this now into mainline allows a smooth queueing of the actual
  conversion in the affected maintainer trees without creating
  dependencies"

Currently we use current_stack_pointer() function to get the value
of the stack pointer register. Since commit:

  f5caf621 ("x86/asm: Fix inline asm call constraints for Clang")

... we have a stack register variable declared. It can be used instead of
current_stack_pointer() function which allows to optimize away some
excessive "mov %rsp, %<dst>" instructions:

 -mov    %rsp,%rdx
 -sub    %rdx,%rax
 -cmp    $0x3fff,%rax
 -ja     ffffffff810722fd <ist_begin_non_atomic+0x2d>

 +sub    %rsp,%rax
 +cmp    $0x3fff,%rax
 +ja     ffffffff810722fa <ist_begin_non_atomic+0x2a>

Remove current_stack_pointer(), rename __asm_call_sp to current_stack_pointer
and use it instead of the removed function.

Some routines in mem_encrypt.c are called very early in the boot process,
e.g. sme_encrypt_kernel(). When CONFIG_TRACE_BRANCH_PROFILING=y is defined
the resulting branch profiling associated with the check to see if SME is
active results in a kernel crash. Disable branch profiling for
mem_encrypt.c by defining DISABLE_BRANCH_PROFILING before including any
header files.

Merge branch 'fixes-v4.14-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security

Pull keys fixes from James Morris:
 "Notable here is a rewrite of big_key crypto by Jason Donenfeld to
  address some issues in the original code.

  From Jason's commit log:
   "This started out as just replacing the use of crypto/rng with
    get_random_bytes_wait, so that we wouldn't use bad randomness at
    boot time. But, upon looking further, it appears that there were
    even deeper underlying cryptographic problems, and that this seems
    to have been committed with very little crypto review. So, I rewrote
    the whole thing, trying to keep to the conventions introduced by the
    previous author, to fix these cryptographic flaws."

  There has been positive review of the new code by Eric Biggers and
  Herbert Xu, and it passes basic testing via the keyutils test suite.
  Eric also manually tested it.

  Generally speaking, we likely need to improve the amount of crypto
  review for kernel crypto users including keys (I'll post a note
  separately to ksummit-discuss)"

* 'fixes-v4.14-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security:
  security/keys: rewrite all of big_key crypto
  security/keys: properly zero out sensitive key material in big_key
  KEYS: use kmemdup() in request_key_auth_new()
  KEYS: restrict /proc/keys by credentials at open time
  KEYS: reset parent each time before searching key_user_tree
  KEYS: prevent KEYCTL_READ on negative key
  KEYS: prevent creating a different user's keyrings
  KEYS: fix writing past end of user-supplied buffer in keyring_read()
  KEYS: fix key refcount leak in keyctl_read_key()
  KEYS: fix key refcount leak in keyctl_assume_authority()
  KEYS: don't revoke uninstantiated key in request_key_auth_new()
  KEYS: fix cred refcount leak in request_key_auth_new()

We currently route pte translation faults via do_page_fault, which elides
the address check against TASK_SIZE before invoking the mm fault handling
code. However, this can cause issues with the path walking code in
conjunction with our word-at-a-time implementation because
load_unaligned_zeropad can end up faulting in kernel space if it reads
across a page boundary and runs into a page fault (e.g. by attempting to
read from a guard region).

In the case of such a fault, load_unaligned_zeropad has registered a
fixup to shift the valid data and pad with zeroes, however the abort is
reported as a level 3 translation fault and we dispatch it straight to
do_page_fault, despite it being a kernel address. This results in calling
a sleeping function from atomic context:

Fix this by dispatching all translation faults to do_translation_faults,
which avoids invoking the page fault logic for faults on kernel addresses.
