can return three states, DMA_TX_RUNNING, DMA_TX_COMPLETE,
DMA_TX_PAUSED.

Convert the device_terminate_all() operation on the
DMA engine to a generic device_control() operation
which can now optionally support also pausing and
resuming DMA on a certain channel. Implemented for the
COH 901 318 DMAC as an example.

GCC's __builtin_prefetch() was introduced a long time ago, all
supported GCC versions have it. Lets do what the big boys up in
linux/prefetch.h do, except we use '1' as the third parameter to
provoke 'PREF 0,...' and 'PREF 1,...' instead of other prefetch
hints.
This allows for better code generation. In theory the existing
embedded asm could be optimized, but the compiler has these builtins,
so there is really no point.

For the simulator, fake a slow clock to get fast output.
In prom_putchar we have to mask the value so the simulator doesn't
ASSERT when printing non-ASCII characters.

ar7_regiser_devices needs ar7_clocks_init to have been called first,
however clock.o is currently linked later due to its order in the Makefile,
therefore ar7_clocks_init always gets called later than ar7_register_devices
because both have the same initcall level. Fix this by moving
ar7_register_devices to the right initcall level.

The "nofpu" and "nodsp" kernel command line options currently do not
affect CPUs that are brought online later in the boot process or
hotplugged at runtime. It is desirable to apply the nofpu/nodsp options
to all CPUs in the system, so that surprising results are not seen when
a process migrates from one CPU to another.
[Ralf: Moved definitions of mips_fpu_disabled, fpu_disable,
mips_dsp_disabled and dsp_disable from setup.c to cpu-probe.c to allow
making mips_fpu_disabled and mips_dsp_disabled static.]

Use set_cpus_allowed_ptr rather than set_cpus_allowed.

The Touch controller and LCD Panel share the same SPI bus 1.
So, we need to define the touch controller in the SPI board info
else, the SPI bus will be contended due to invalid state of
Touch controller's Chip Select thus preventing the LCD panel
from working.

The previous AES-NI CTR optimization compiling failure gas 2.16.1 fix

Andrew Morton reported that AES-NI CTR optimization failed to compile
with gas 2.16.1, the error message is as follow:
arch/x86/crypto/aesni-intel_asm.S: Assembler messages:
arch/x86/crypto/aesni-intel_asm.S:752: Error: suffix or operands invalid for `movq'
arch/x86/crypto/aesni-intel_asm.S:753: Error: suffix or operands invalid for `movq'
To fix this, a gas macro is defined to assemble movq with 64bit
general purpose registers and XMM registers. The macro will generate
the raw .byte sequence for needed instructions.

To take advantage of the hardware pipeline implementation of AES-NI
instructions. CTR mode cryption is implemented in ASM to schedule
multiple AES-NI instructions one after another. This way, some latency
of AES-NI instruction can be eliminated.
Performance testing based on dm-crypt should 50% reduction of
ecryption/decryption time.

Based on a patch from Brent DeGraaf:
"The datamover supports channels which can be shared amongst devices.
As a result, the actual data transfer may occur some time after the
request is queued up. Some devices such as mmc host controllers
will timeout if a command is issued too far in advance of the actual
transfer, so if dma to other devices on the same channel is already
in progress or queued up, the added delay can cause pending transfers
to fail before they start. This change extends the api to allow a
user callback to be invoked just before the actual transfer takes
place, thus allowing actions directly associated with the dma
transfer, such as device commands, to be invoked with precise timing.
Without this mechanism, there is no way for a driver to realize
this timing. Also adds a user pointer to the command structure for use
by the caller to reference information that may be needed by the
callback routine for proper identification and processing associated
with that specific request. This change is necessary to fix problems
associated with excessive command timeouts and race conditions in the
mmc driver."
This patch also fixes all the callers of msm_dmov_enqueue_cmd() to
ensure their callback function is NULL.

'protect4gb' boot parameter was introduced to avoid allocating dma
space acrossing 4GB boundary in 2007 (the commit
569975591c5530fdc9c7a3c45122e5e46f075a74).
In 2008, the IOMMU was fixed to use the boundary_mask parameter per
device properly. So 'protect4gb' workaround was removed (the
383af9525bb27f927511874f6306247ec13f1c28). But somehow I messed the
'protect4gb' boot parameter that was used to enable the
workaround.
