David Howells 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.

Rene Herman cf40a310a7 [ALSA] AdLib FM card driver
Attached you'll find an ALSA driver for AdLib FM cards. An AdLib card is
just an OPL2, which was already supported by sound/drivers/opl3, so only
very minimal bus-glue is needed. The patch applies cleanly to both
2.6.16 and 2.6.16-mm1.

The driver has been tested with an actual ancient 8-bit ISA AdLib card
and works fine. It also works fine for an OPL3 {,emulation} as still
found on many ISA soundcards but given that AdLib cards don't have their
own mixer, upping the volume from 0 might be a problem without the card
driver already loaded and driving the OPL3.

Mark Salazar 95b712965f [ALSA] #4/4 for Zoom Video - add Zoom Video support
Modules: ES18xx driver

Forth of 4 es18xx.c patches culminating in Zoom Video support.

This patch adds Zoom Video support for those chipsets that support it.

Testing:
This work was initially done on the source from the Debian Sarge ALSA
package, then tested
on an ES1879. I could not test the Zoom Video function for an ES1878 or
ES1869.
Patches were created against the Sarge code and then edited to apply
correctly to the
ALSA cvs code. Lastly the patched ALSA cvs code was test for successful
compilation.
No additional testing was done on the ALSA cvs version.

One quirk (noted in my comments below) is that apparently the datasheet
is wrong
for one of the ES1879 Zoom Video 'enable' bits, because
 1) if you set this bit it messes up PCM playback (speaker_test play a
lower frequency)
 2) even if you don't set this bit Zoom Video still works.
I added a control to toggle the bit on just in case there might be a
version of the
ES1879 that requires it, but I expect noone will need it.

Mark Salazar 14086771c0 [ALSA] #3/4 for Zoom Video - change Hardware Volume interrupt handling
Modules: ES18xx driver

Third of 4 es18xx.c patches culminating in Zoom Video support.

This patch changes the Hardware Volume support to reflect the fact that
not all of the
supported chipsets have seperate registers dedicated to the Hardware
Volume inputs. Although
all the chipsets can generate an HWV interrupt whenever a Hardware
Volume input is received
only those with seperate HWV registers can split the HWV registers from
the Master volume
registers.

Testing:
This work was initially done on the source from the Debian Sarge ALSA
package, then tested
on an ES1879 and an ES1878 machine. Patches were created against the
Sarge code and then edited
to apply correctly to the ALSA cvs code. Lastly the patched ALSA cvs
code was test for
successful compilation. No additional testing was done on the ALSA cvs
version.

Mark Salazar f4df221f8f [ALSA] #2/4 for Zoom Video - resolve number of record sources
Modules: ES18xx driver

Second of 4 es18xx.c patches culminating in Zoom Video support.

This patch changes the 'record source' mux routines to reflect the fact
that not all of the
supported chipsets have 8 possible inputs. Some have 4 and some have 5.

Testing:
This work was initially done on the source from the Debian Sarge ALSA
package, then tested
on an ES1879 and an ES1878 machine. Patches were created against the
Sarge code and then edited
to apply correctly to the ALSA cvs code. Lastly the patched ALSA cvs

successful compilation. No additional testing was done on the ALSA cvs
