Start cleaning up the voltage layer to have a voltage domain layer
that resembles the structure of the existing clock and power domain
layers. To that end:
- move the 'struct voltagedomain' out of 'struct omap_vdd_info' to
become the primary data structure.
- convert any functions taking a pointer to struct omap_vdd_info into
functions taking a struct voltagedomain pointer.
- convert the register & initialize of voltage domains to look like
that of powerdomains
- convert omap_voltage_domain_lookup() to voltdm_lookup(), modeled
after the current powerdomain and clockdomain lookup functions.
- omap_voltage_late_init(): only configure VDD info when
the vdd_info struct is non-NULL

Eliminate need for global variables for the various PRM module offsets by
making them part of the VP/VC common structures
Eventually, these will likely be moved again, or more likely removed
when VP/VC code is isolated, but for now just getting rid of them as
global variabes so that the voltage domain initialization can be
cleaned up.

The voltage domain pointer currently in struct omap_hwmod is not used

When I last posted the patch, the ceph bit was ACK'ed by Sage Weil, so
I've added that below.
The pwc-ioctl change generated quite a bit of discussion about V4L version
numbers in general, but as far as I can tell, no concensus was reached on
what the long term solution should be, so in the mean time I think we
could start by just removing the unneeded include, which is why I'm

With this driver, all the devices paired to a single Unifying
receiver are exposed to user processes in separated /input/dev
nodes.
Keyboards with different layouts can be treated differently,
Multiplayer games on single PC (like home theater PC) can
differentiate input coming from different kbds paired to the
same receiver.
Up to now, when Logitech Unifying receivers are connected to a
Linux based system, a single keyboard and a single mouse are
presented to the HID Layer, even if the Unifying receiver can
pair up to six compatible devices. The Unifying receiver by default
multiplexes all incoming events (from multiple keyboards/mice)

wait_for_avail() in pcm_lib.c has a race in it (observed in practice by an
Intel validation group).
The function is supposed to return once space in the buffer has become
available, or if some timeout happens. The entity that creates space (irq
handler of sound driver and some such) will do a wake up on a waitqueue
that this function registers for.
However there are two races in the existing code
1) If space became available between the caller noticing there was no
space and this function actually sleeping, the wakeup is missed and the
timeout condition will happen instead
2) If a wakeup happened but not sufficient space became available, the
code will loop again and wait for more space. However, if the second
wake comes in prior to hitting the schedule_timeout_interruptible(), it
will be missed, and potentially you'll wait out until the timeout
happens.
The fix consists of using more careful setting of the current state (so
that if a wakeup happens in the main loop window, the schedule_timeout()
falls through) and by checking for available space prior to going into the
schedule_timeout() loop, but after being on the waitqueue and having the
state set to interruptible.

- merged akpm's fix for waitqueue adding order into a single patch
- reduction of duplicated code of avail check
