ima: Fix build failure on powerpc when TCG_IBMVTPM dependencies are not met

On powerpc we can end up with IMA=y and PPC_PSERIES=n which leads to:

 warning: (IMA) selects TCG_IBMVTPM which has unmet direct dependencies (TCG_TPM && PPC_PSERIES)
  tpm_ibmvtpm.c:(.text+0x14f3e8): undefined reference to `.plpar_hcall_norets'

I'm not sure why IMA needs to select those user-visible symbols, but if
it must then the simplest fix is to just express the proper dependencies
on the select.

Merge branch 'amdkfd-next-3.19' of git://people.freedesktop.org/~gabbayo/linux into drm-next

As discussed on irc, I'm sending a pull request with one important change:

- Disable support for 32-bit user processes. This is done due to AMD's decision
  to remove support for 32-bit user processes on Linux for its HSA stack.

Bluetooth: Fix generation of non-resolvable private addresses

When the host decides to use a non-resolvable private address, it
must ensure that this generated address does not match the public
address of the controller. Add an extra check to ensure this required
behavior.

In addition rename the variable from urpa to nrpa and fix all of the
comments in the code that use the term unresolvable instead of the
term non-resolvable as used in the Bluetooth specification.

i2c: designware: Fix falling time bindings doc

In (6468276 i2c: designware: make SCL and SDA falling time
configurable) new device tree properties were added for setting the
falling time of SDA and SCL.  The device tree bindings doc had a typo
in it: it forgot the "-ns" suffix for both properies in the prose of
the bindings.

I assume this is a typo because:
* The source code includes the "-ns"
* The example in the bindings includes the "-ns".

Fix the typo.

xen: introduce helper functions to do safe read and write accesses

Introduce two helper functions to safely read and write unsigned long
values from or to memory when the access may fault because the mapping
is non-present or read-only.

These helpers can be used instead of open coded uses of __get_user()
and __put_user() avoiding the need to do casts to fix sparse warnings.

Use the helpers in page.h and p2m.c. This will fix the sparse
warnings when doing "make C=1".
