There are actually only four separate implementations of set_pte_ext.
Use assembler macros to insert code for these into the proc-*.S files.

There's no point scattering this around the tree, the parsing
of the parameter might as well live beside the code which uses
it. That also means we can make vmalloc_reserve a static
variable.

- Don't re-enable I/D caches if they were not enabled initially.
- Change some masks to shifts for better generated code.

As per the dma_unmap_* calls, we don't touch the cache when a DMA
buffer transitions from device to CPU ownership. Presently, no
problems have been identified with speculative cache prefetching
which in itself is a new feature in later architectures. We may
have to revisit the DMA API later for these architectures anyway.

The name of the platform device 'at91_pwm_leds' conflicts with the
function at91_pwm_leds().
So rename the device 'at91_pwm_leds_device' to be more specific.
Similarly rename 'at91_gpio_leds_device' for consistency.

dma_map_* when using the DMA bounce code.

The dmabounce dma_sync_xxx() implementation have been broken for
quite some time; they all copy data between the DMA buffer and
the CPU visible buffer no irrespective of the change of ownership.
(IOW, a DMA_FROM_DEVICE mapping copies data from the DMA buffer
to the CPU buffer during a call to dma_sync_single_for_device().)
Fix it by getting rid of sync_single(), moving the contents into
the recently created dmabounce_sync_for_xxx() functions and adjusting
appropriately.
This also makes it possible to properly support the DMA range sync
functions.

When configured as a specific low power state: MFP_LPM_DRIVE_LOW,
MFP_LPM_DRIVE_HIGH, the corresponding GPDR register bit during
low power mode shall be re-configured as output (if they are not
configured so), thus the PGSRx bits can output.
Create an additional low power values GPDR registers, and properly
save/restore the GAFR + GPDR registers when doing suspend/resume.

This patch adds specific power-off method for Buffalo Linkstation Mini
board. The board has a hardware switch which should be monitored from
userspace. When the switch is in OFF position the board should be rebooted
and U-Boot will start in an idle mode and wait for the user to move the
power switch back to ON position.

Add support to the Kirkwood port for newer device models and silicon
revisions. Instead of looking at the DEVICE_ID register, the device
version is now determined by looking at the PCI-Express device ID and
revision registers, as it is done for orion5x, and this information
is used to determine the TCLK frequency, again, as it is done for
orion5x.
