staging: unisys: visorinput: remove need for 'depends on FB'

Previously, we used a hack to determine the max x,y resolution of the
visor virtual mouse: we just looked at the resolution of the
first-registered framebuffer device, using the currently-valid assumption
that in a Unisys s-Par guest environment the video will be provided by an
efifb framebuffer device.

This hack has been removed, by instead determining the default mouse
resolution by looking at fields within the visor mouse channel memory,
mouse.x_res and mouse.y_res.  If these fields are 0, a default resolution
of 1024x768 is assumed.

  * changed the types of a number of index and length variables from
    signed to unsigned integer types.

  * changed the return-types of a couple of functions that return length

    unsigned integer types.

It's possible that only one of the two sides actually access the members,
but it's clear that they need to agree on the layout. The easiest way
to achieve this appears to be to merge the two files into one. I tried
moving the structure definition into a shared header first, but ended
up running into too many interdependencies that way.

staging: lustre: replace l_wait_event_exclusive_head() with wait_event_idle_exclusive

This l_wait_event_exclusive_head() will wait indefinitely
if the timeout is zero.  If it does wait with a timeout
and times out, the timeout for next time is set to zero.

The can be mapped to a call to either
 wait_event_idle_exclusive()
or
 wait_event_idle_exclusive_timeout()
depending in the timeout setting.

The current code arranges for LIFO queuing of waiters,
but include/event.h doesn't support that yet.
Until it does, fall back on FIFO with
wait_event_idle_exclusive{,_timeout}().

staging: lustre: remove l_wait_event from ptlrpc_set_wait

This is the last remaining use of l_wait_event().
It is the only use of LWI_TIMEOUT_INTR_ALL() which
has a meaning that timeouts can be interrupted.
Only interrupts by "fatal" signals are allowed, so
introduce l_wait_event_abortable_timeout() to
support this.

We can replace l_wait_event() with
wait_event_idle_timeout() here providing we call the
timeout function when wait_event_idle_timeout() returns zero.

As ptlrpc_expired_set() returns 1, the l_wait_event() aborts of the
first timeout.

staging: lustre: remove back_to_sleep()

When 'back_to_sleep()' is passed as the 'timeout' function,
the effect is to wait indefinitely for the event, polling
once after the timeout.
If LWI_ON_SIGNAL_NOOP is given, then after the timeout
we allow fatal signals to interrupt the wait.

Make this more obvious in both places "back_to_sleep()" is
used but using two explicit sleeps.

The code in ptlrpcd_add_req() looks odd - why not just have one
wait_event_idle()?  However I believe this is a faithful
transformation of the existing code.
