166fb6b472 V4L/DVB (6623): remove saa7134-oss
The saa7134-oss is deprecated for quite some time, it's the only remaining OSS
user outside of sound/oss/, and considering how few and what kind of
soundcards are left supported by OSS I hardly see any use cases left.

843b1378c2 V4L/DVB (6690): saa7134: fix ignored interrupts
The saa7134 video driver starts dropping frames when used together with the
saa7134-alsa driver. Frames are dropped because when an audio event is waiting
the driver simply ignores the interrupt and passes it on to the saa7134-alsa
interrupt handler. The alsa interrupt handler in turn acknowledges all types
of events thus clearing the pending video events as well. Fix by only masking
out the audio event in the video interrupt handler and by only acknowledging
the audio event in the alsa driver.

174eb8e8cb V4L/DVB (6666): saa7134-alsa: fix period handling
The period handling in saa7134-alsa is broken in two ways. First, the
minimum number of periods of two does not work, because the dma is setup
two periods ahead in the irq handler. Fix the minimum to four periods.
Second, the code assumes that the number of periods is divisible by two,
which isn't always the case on ALSA. Fix by adding a constraint.

You are right. The patch below (based on your cx88 patch, but I don't
really understand it) fixes mmap support in saa7134-alsa for me.
Recording via mmap (arecord -M -f S16_LE -c 2 -r 32000 -D hw:1) didn't
work at all before, works now, tested for at least 20 minutes (but,
unfortunately, with one overrun at least 0.719 ms long).

b930e1d851 V4L/DVB (6125): whitespace cleanup: replace leading spaces with tabs
There were many instances of 7-space indents spread throughout
the v4l-dvb tree.

This patch replaces the 7-space indents with tabs.  The whitespace cleaner
script doesn't catch these, because it assumes that all indents are 8-space.

aac0ca6a8b V4L/DVB (5775): Alsa fix for SAA7134 based "KNC One TV-Station DVR" card
Sound recording doesn't work for this card because ACNI and ACPF
are not set before snd_card_saa7134_capture_prepare(). As a result
timeout occurs. These registers aren't poked because thread
never gets wake up signal. ACNI initialization is done in the
thread.
Sound is muted when capture stops. Shouldn't be because it may
be used during TV playback.

5cfbacd0d3 V4L/DVB (4872): Saa7134-alsa improvements
The change does the following:
- At device open, it sets the recording source to the current
  input instead of LINE2. So it is no longer necessary to set the
  recording source with a mixer application.
- Connects the mixer volume control to the input sensitivity selection
  of the analog sound inputs. This allows only one 6db step.

7d12e780e0 IRQ: Maintain regs pointer globally rather than passing to IRQ handlers
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.

The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around.  On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).

Where appropriate, an arch may override the generic storage facility and do
something different with the variable.  On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.

Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions.  Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller.  A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.

I've build this code with allyesconfig for x86_64 and i386.  I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.

This will affect all archs.  Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:

	struct pt_regs *old_regs = set_irq_regs(regs);

And put the old one back at the end:

	set_irq_regs(old_regs);

Don't pass regs through to generic_handle_irq() or __do_IRQ().

In timer_interrupt(), this sort of change will be necessary:

	-	update_process_times(user_mode(regs));
	-	profile_tick(CPU_PROFILING, regs);
	+	update_process_times(user_mode(get_irq_regs()));
	+	profile_tick(CPU_PROFILING);

I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().

Some notes on the interrupt handling in the drivers:

 (*) input_dev() is now gone entirely.  The regs pointer is no longer stored in
     the input_dev struct.

 (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking.  It does
     something different depending on whether it's been supplied with a regs
     pointer or not.

 (*) Various IRQ handler function pointers have been moved to type
     irq_handler_t.
