Commit 787314c3 ("Merge tag 'iommu-updates-v3.8' of
git://git./linux/kernel/git/joro/iommu") did not account for the changed
header location.

The headers were made local to mach-omap2 as they are specific to omap2+
only, and we wanted to get most of the #include <plat/*.h> headers fixed
up anyways for the ARM multiplatform support.

We attempted to avoid this kind of merge conflict early on by setting up
a minimal git branch shared by the arm-soc tree and the iommu tree, but
looks like we still hit a merge issue there as the branches got merged
as various topic branches.

Fix up three empty files in arch/cris/ by sticking placeholder comments in
there to prevent the patch program from deleting them.

I decided not to delete the arch-v*/Kbuild files as it's possibly someone might
want to use them for genhdr-y lines in the future, but they could be deleted
and the pointer lines removed from asm/Kbuild.  The uapi/arch-v*/Kbuild files
ought to be uneffected by such a change.

asm/swab.h didn't have anything outside of __KERNEL__ so nothing appeared in
uapi/asm/swab.h.  The latter, however, is exported by Kbuild.asm.

This needs to be applied after the CRIS UAPI disintegration patch.

Like the generic versions, we need to support a block size
of '1' for CTR mode AES.

This was discovered thanks to all of the new test cases added by
Jussi Kivilinna.
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The basic scheme of the block mode assembler is that we start by
enabling the FPU, loading the key into the floating point registers,
then iterate calling the encrypt/decrypt routine for each block.

For the 256-bit key cases, we run short on registers in the unrolled
loops.

So the {ENCRYPT,DECRYPT}_256_2() macros reload the key registers that
get clobbered.

The unrolled macros, {ENCRYPT,DECRYPT}_256(), are not mindful of this.

So if we have a mix of multi-block and single-block calls, the
single-block unrolled 256-bit encrypt/decrypt can run with some
of the key registers clobbered.

Handle this by always explicitly loading those registers before using
the non-unrolled 256-bit macro.

This was discovered thanks to all of the new test cases added by
Jussi Kivilinna.

Device trees allow specification of hardware topology and device
parameters at runtime instead of hard-coding them in platform setup
code. This allows running single binary kernel on a range of compatible
boards.

New boot parameters tag BP_TAG_FDT is allocated and a pointer to flat
device tree is passed in it.

Note that current interrupt mapping scheme uses single cell for
interrupt identification. That means that IRQ numbers used in DTS must
be CPU internal IRQ numbers, not external. It is possible to extend
interrupt identification to two cells, and use second cell to tell
external IRQ numbers form internal. That would allow to use single DTS
on multiple boards with different mapping of external IRQ numbers.
