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.

125ab12acf [ARM] dma: fix dmabounce dma_sync_xxx() implementations
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.

d7161a6534 kgdb, x86, arm, mips, powerpc: ignore user space single stepping
On the x86 arch, user space single step exceptions should be ignored
if they occur in the kernel space, such as ptrace stepping through a
system call.

First check if it is kgdb that is executing a single step, then ensure
it is not an accidental traversal into the user space, while in kgdb,
any other time the TIF_SINGLESTEP is set, kgdb should ignore the
exception.

On x86, arm, mips and powerpc, the kgdb_contthread usage was
inconsistent with the way single stepping is implemented in the kgdb
core.  The arch specific stub should always set the
kgdb_cpu_doing_single_step correctly if it is single stepping.  This
allows kgdb to correctly process an instruction steps if ptrace
happens to be requesting an instruction step over a system call.

0b0740c3c1 [ARM] Orion: add RD88F6183AP-GE support
The RD88F6183AP-GE is an access point reference design for the
88F6183 SoC, with a 88E6161 six-port gigabit ethernet switch with
five PHYs (providing 1 WAN and 4 LAN ports and an interface to the
CPU), and a mini-PCIe slot for a wireless card.

c0e9587841 [ARM] Introduce new bitmask based cache type macros
Rather than trying to (inaccurately) decode the cache type from the
registers each time we need to decide what type of cache we have,
use a bitmask initialized early during boot.

Since the setup is a one-off initialization, we can be a little more
clever and take account of the CPU architecture as well.

Note that we continue to achieve the compactness on optimised kernels
by forcing tests to always-false or always-true as appropriate, thereby
allowing the compiler to do build-time code elimination.

90f1e08478 [ARM] Remove cache type printks
The cache type register found in ARMv5 and later CPUs changes format
and meaning depending on the CPU architecture version.  Currently,
this code:
a) doesn't work for everything - Xscale's are identified as
   'unknown 5'.
b) is not able to tell whether the caches are VIVT or VIPT from the
   cache type.
c) prints rubbish on some ARMv6 and ARMv7+ CPUs.

The two solutions to this are:
1. Add yet more code to decode and print the various different register
   formats.
2. Remove the code altogther.

The code only exists to decode and print the cache parameters.
Increasing the complexity of it just for the sake of a few prinks
isn't worth it.

Certain peripherals are therefore also disabled, and thus cannot be

58005b3253 [ARM] 5255/1: Update jornada ssp to remove build errors/warnings
* Adds ssp functions into header so we don't get
"implicit declaration" error at builtime.
* Converts jornada_ssp_start/end functions into voids with
proper declarations (to avoid "prototype..." warning).
* Sorts include files in alphabetical order
* Minor comment changes

7bff3c4ce4 ARM: DaVinci: evm sets up many devices
Update DaVinci EVM board setup to work with key drivers which are
now in mainline kernels:

 - I2C adapter (driver: i2c_davinci)
    * three gpio expanders (driver: pcf8574) used for
       - LEDs
       - audio codec control
       - misc device control (including USB VBUS, IDE-vs-CF)
    * at24 (driver: at24) eeprom
 - USB controller (driver: musb_hdrc)
 - IDE controller (driver: palm_bk3710)

This board is the first in-tree client for a number of those drivers,
and adding this board support means the EVM board can be used for some
"real work" ... excepting "DaVinci Technology" video and DSP support
(also available in most OMAP3 chips).

Also renames the flash as "evm_norflash", since NAND may be jumpered.

(Patch contains work by myself, Kevin Hilman, Sergei Shtylyov.)

88c381bf09 [ARM] Fix PCI_DMA_BUS_IS_PHYS for ARM
PCI_DMA_BUS_IS_PHYS was defined to be zero, which meant we ignored
the DMA mask for IDE and SCSI transfers.  This is wrong - we have
no DMA translation hardware.  We want to obey DMA masks so that the
block layer performs bouncing itself.

4104980a3c [ARM] pxa: Allow platforms to override PSPR setting
Currently, we set PSPR just before entering sleep mode.  However,
some platforms have different requirements for setting PSPR in
order to properly wake up.

Set PSPR earlier in the suspend cycle so that platforms can
change the setting by using a sysdev driver instead.
