Uwe pointed out that my alarm based UIE emulation is not sufficient
to replace the older timer/polling based UIE emulation on devices
where there is no alarm irq. This causes rtc devices without alarms
to return -EINVAL to UIE ioctls. The fix is to re-instate the old
timer/polling method for devices without alarm irqs.

This patch reverts the following commits:
042620a0 - Remove UIE emulation
1daeddd5 - Cleanup removed UIE emulation declaration
b5cc8ca1 - Remove Kconfig symbol for UIE emulation

The emulation mode will still need to be wired-in with a following
patch before it will work.

On hardware that doesn't support alarm interrupts, rtc_alarm_irq_enable

This was introduced in

This patch corrects the issue by only returning once the mutex is
released.

There is a double completion associated with error handling for RC QPs.

The sequence is:

 - The do_rc_ack() routine fields an RNR nack and there are 0
   rnr_retries configured on the QP.
 - qib_error_qp() stops the pending timer
 - qib_rc_send_complete() is called from sdma_complete()
 - qib_rc_send_complete() starts the timer because the msb of the psn
   just completed says an ack is needed.
 - a bunch of flushes occur as ipoib posts WQEs to an error'ed QP
 - rc_timeout() calls qib_restart_rc()
 - qib_restart_rc() calls qib_send_complete() with a
   IB_WC_RETRY_EXC_ERR on a wqe that has already been completed in the
   past

The fix avoids starting the timer since another packet will never
arrive.

The driver was not flushing all writebacks before unloading, possibly

This adds missing functionality to flush any pending writebacks and is

Due to the default case handling the older chipsets, a bunch of the newer
ones ended up having the wrong tiling regs used.  This commit switches the
default case to handle the newest chipsets.

This also makes nv4e touch the "extra" tiling regs.  "nv" doesn't touch
them for C51 but traces of the NVIDIA binary driver show it being done
there.

I couldn't find NV41/NV45 traces to confirm the behaviour there, but an
educated guess was taken at each of them.
