[ARM/tegra] dma: add transfer count query. Checking interrupt pending status.
Stopping Dma after last req transfer.
add an API to return the completed transfer count of a pending, active
or finished DMA request
originally fixed by Gary King <gking@nvidia.com>
It is observed that the dma interrupt has the lower priority then
its client interupt priority. When client's isr calls dma get transfer,
the dma status has not been upated as dma isr have not been served yet.
So before reading the status, explicitly checking the interrupt status and
handling accordingly.
The another issue which is observed is that if dma has transferred the data
of amount = requested -4 and if it moves to invalid requestor before stopping
then status got reset and tarnsfered bytes becomes 0. This seems the apb dma
hw behavior. Following is the suggestion to overcome this issue:
- Disable global enable bit.
- Read status.
- Stop dma.
- Enable global status bit.
Added this workaround and it worked fine.
originally fixed by Laxman Dewangan <ldewangan@nvidia.com>
In continous mode, dma should stop after last transfer completed and
if there is no more req pending.
If there is pending req then it should check whether it has updated
in hw for next transfer or not and if it has not started then stop dma
and start new req immediatley.

Un-inline the core-dump helper functions
Tony Luck reports that the addition of the access_ok() check in commit
0eead9ab41da ("Don't dump task struct in a.out core-dumps") broke the
ia64 compile due to missing the necessary header file includes.
Rather than add yet another include (<asm/unistd.h>) to make everything
happy, just uninline the silly core dump helper functions and move the
bodies to fs/exec.c where they make a lot more sense.
dump_seek() in particular was too big to be an inline function anyway,
and none of them are in any way performance-critical. And we really
don't need to mess up our include file headers more than they already
are.

Don't dump task struct in a.out core-dumps
akiphie points out that a.out core-dumps have that odd task struct
dumping that was never used and was never really a good idea (it goes
back into the mists of history, probably the original core-dumping
code). Just remove it.
Also do the access_ok() check on dump_write(). It probably doesn't
matter (since normal filesystems all seem to do it anyway), but he
points out that it's normally done by the VFS layer, so ...
[ I suspect that we should possibly do "vfs_write()" instead of
calling ->write directly. That also does the whole fsnotify and write
statistics thing, which may or may not be a good idea. ]
And just to be anal, do this all for the x86-64 32-bit a.out emulation
code too, even though it's not enabled (and won't currently even
compile)

-- Ignore kfifo thresholds on recording and playback and adjust the delays.
-- Take out the code from TEGRA_AUDIO_IN_STOP into a separate function
stop_recording_nosync()
-- Rename stop_recording() to wait_for_recording_to_stop().
-- add ioctl(TEGRA_AUDIO_OUT_FLUSH), which blocks the caller until the output
fifo is drained. While the caller is blocked, pending write() calls will
return immediately with whatever data they had managed to queue up.
-- removed ioctl(TEGRA_AUDIO_OUT_PRELOAD_FIFO)
-- since TEGRA_AUDIO_OUT_FLUSH and TEGRA_AUDIO_IN_STOP act similarly, moved
audio_driver_state::recording_cancelled to audio_stream::stop and changed
the code accordingly. Renamed functions wait_for_recording_to_stop() and
stop_recording_nosync() to wait_till_stopped() and request_stop_nosync()
since they handle both playback and recording.
-- print errors on close() if wakelocks are still held
-- Call request_stop_nosync() on close() of a recording file handle
-- Do not use struct audio_stream::active for playback streams. Instead,
where applicable, use kfifo_len(). As a consequence, playback kfifo
underruns are no longer reported. These were bogus anyway, as we really
need the DMA engine to tell us if there are underruns.
-- Because of above item, had to rework tx_fifo_atn_store(),
rx_fifo_atn_store(), and __attr_fifo_atn_write().
-- Set struct audio_stream::active for a recording stream to true when a
recording starts, and set it to false when recording get stopped. Do not
set/clear it within the body of read(), because just being within read()
does not mean that recording is in progress.
-- In tegra_audio_read(), check for stop == true before calling
start_recording_if_necessary(); this makes sure that if a user calls read()
after calling ioctl(TEGRA_AUDIO_IN_STOP), recording will not resume unless
ioctl(TEGRA_AUDIO_IN_START) gets called, or the file is closed and
re-opened.
-- Fixed TEGRA_AUDIO_IN_START
-- In PIO mode, enabled FIFOs before enabling interrupts as specified in the
TRM.
-- Added missing break in tegra_audio_ioctl().
-- Silenced some debug spew
