The flush_iotlb_page is not loading the cam register before flushing
the cam entry. This causes wrong entry to be flushed out from the TLB, and
if the entry happens to be a locked TLB entry it would lead to MMU faults.
The fix is to load the cam register with the address to be flushed before
flushing the TLB entry.

Currently we map 1 MB section while setting up SRAM on OMAPs
Regardless of the actual memory. The physical OCM RAM available
on OMAP SOCs is in order of KBs. This patch maps only available
sram and cleans up some un-necessary cpu_is_xxx checks.
Mapping un-available or non-accessible(secure) memory on the newer ARM
processor is dangerous. Because ARM CPUs can now speculatively prefetch,
we should avoid mapping any no-existing or secure memory.

With this patch, you'll get the following sysfs directories. This
structure implies that a single platform device, "omap2-mailbox" holds
multiple logical mbox instances. This could be the base to add sysfs
files for each logical mboxes. Then userland application can access a
mbox through sysfs entries if necessary(ex: setting kfifo size
dynamically)

The underlying buffering implementation of mailbox
is converted from block API to kfifo due to the simplicity
and speed of kfifo.
The default size of the kfifo buffer is set to 256 bytes.
This value is configurable at compile time (via
CONFIG_OMAP_MBOX_KFIFO_SIZE), and can be changed at
runtime (via the mbox_kfifo_size module parameter).

Add omap_pm_set_min_clk_rate(). This constraint is meant for use by
device drivers to translate a certain device-specific performance
constraint (e.g., "minimum polygons per second") to a clock rate for
the driver's device, given the driver's intimate knowledge of the
device hardware (e.g., device type, device hardware revision, firmware
revision, etc.) From a general PM core perspective, clock rate is
probably the closest general analog to "performance" that is
available, but the exact mapping from a use-case-specific performance
constraint to clock rate must be done by the driver. Drivers intended for
upstream merging shouldn't hardcode specific clock rates in their code
without basing those rates on some performance criteria requested through
the driver's subsystem (ideally, from userspace).
Imre Deak <imre.deak@nokia.com> described the need and use-case for
this constraint, and discussed the implementation - thanks, Imre.

omap_pm_set_max_dev_wakeup_lat()
Add return values to the PM constraint functions. This allows the PM
core to provide feedback to the caller if a constraint is not
possible. Update the one upstream user of omap_pm_set_max_mpu_wakeup_lat()
to add a compatibility wrapper, needed until the driver is changed.
Update some of the documentation to conform more closely to kerneldoc style.
Add an additional device parameter to omap_pm_set_max_dev_wakeup_lat()
to identify the device requesting the constraint. This is so repeated calls
to omap_pm_set_max_dev_wakeup_lat() with the same requesting device can
override the device's previously-set constraint. Also, it allows the PM
core to make a decision as to whether or not the constraint should be
satisfied, based on the caller's identity.
