Replace existing hw_ranndom/exynos-rng driver with a new, reworked one.
This is a driver for pseudo random number generator block which on
Exynos4 chipsets must be seeded with some value.  On newer Exynos5420
chipsets it might seed itself from true random number generator block
but this is not implemented yet.

New driver is a complete rework to use the crypto ALGAPI instead of
hw_random API.  Rationale for the change:
1. hw_random interface is for true RNG devices.
2. The old driver was seeding itself with jiffies which is not a
   reliable source for randomness.
3. Device generates five random 32-bit numbers in each pass but old
   driver was returning only one 32-bit number thus its performance was
   reduced.

Compatibility with DeviceTree bindings is preserved.

New driver does not use runtime power management but manually enables
and disables the clock when needed.  This is preferred approach because
using runtime PM just to toggle clock is huge overhead.

Another difference is reseeding itself with generated random data
periodically and during resuming from system suspend (previously driver
was re-seeding itself again with jiffies).

Often all is needed is these small helpers, instead of compiler.h or a
full kprobes.h.  This is important for asm helpers, in fact even some
asm/kprobes.h make use of these helpers...  instead just keep a generic
asm file with helpers useful for asm code with the least amount of
clutter as possible.

Likewise we need now to also address what to do about this file for both
when architectures have CONFIG_HAVE_KPROBES, and when they do not.  Then
for when architectures have CONFIG_HAVE_KPROBES but have disabled
CONFIG_KPROBES.

Right now most asm/kprobes.h do not have guards against CONFIG_KPROBES,
this means most architecture code cannot include asm/kprobes.h safely.
Correct this and add guards for architectures missing them.
Additionally provide architectures that not have kprobes support with
the default asm-generic solution.  This lets us force asm/kprobes.h on
the header include/linux/kprobes.h always, but most importantly we can
now safely include just asm/kprobes.h on architecture code without
bringing the full kitchen sink of header files.

Two architectures already provided a guard against CONFIG_KPROBES on its
kprobes.h: sh, arch.  The rest of the architectures needed gaurds added.
We avoid including any not-needed headers on asm/kprobes.h unless
kprobes have been enabled.

In a subsequent atomic change we can try now to remove compiler.h from
include/linux/kprobes.h.

During this sweep I've also identified a few architectures defining a
common macro needed for both kprobes and ftrace, that of the definition
of the breakput instruction up.  Some refer to this as
BREAKPOINT_INSTRUCTION.  This must be kept outside of the #ifdef
CONFIG_KPROBES guard.

I and Sergey would like to volunteer as printk code maintainers.
It is a code that everyone is using, various people fix bugs or
even add features but there is nobody really interested into
maintaining it.

I and Sergey have put a lot of effort into understanding the code
and related problems. We are working on solutions for some long
term problems. There is a nice summary from the Kernel Summit
presentation, see https://lwn.net/Articles/705938/

We have already started to use the gained knowledge and comment
on other printk-related patches. The official role should help
us to do it more effectively.

Our priorities are:

    + prevent deadlocks (printk_safe patchset, console locks)
    + prevent softlocks (async printk, console_sem and flushing)
    + handle other bugs/fixes/features as they come

with this in mind:

    + printk is used in different context
    + need special care in some modes, e.g. oops, panic, suspend
    + do best effort to store/show messages
    + the code is already pretty complicated and twisted;
      support clean ups; always think hard if a feature/fix
      is worth any complication

Of course, it still will be much appreciated if other people review
printk patches.

Regarding the workflow. It will be highly appreciated if the patches
might still go via Andrew's -mm tree at least for 4.10. In the long
term, we would like to make Andrew's life easier and handle printk
patches in an own git tree. But we first need to set it up and get
familiar with the processes.

Previously, each filesystem configured without encryption support would
define all the public fscrypt functions to their notsupp_* stubs.  This
list of #defines had to be updated in every filesystem whenever a change
was made to the public fscrypt functions.  To make things more
maintainable now that we have three filesystems using fscrypt, split the
old header fscrypto.h into several new headers.  fscrypt_supp.h contains
the real declarations and is included by filesystems when configured
with encryption support, whereas fscrypt_notsupp.h contains the inline
stubs and is included by filesystems when configured without encryption
support.  fscrypt_common.h contains common declarations needed by both.
