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.

b68e31d0eb [PATCH] const struct tty_operations
As part of an SMP cleanliness pass over UML, I consted a bunch of
structures in order to not have to document their locking.  One of these
structures was a struct tty_operations.  In order to const it in UML
without introducing compiler complaints, the declaration of
tty_set_operations needs to be changed, and then all of its callers need to
be fixed.

This patch declares all struct tty_operations in the tree as const.  In all
cases, they are static and used only as input to tty_set_operations.  As an
extra check, I ran an i386 allyesconfig build which produced no extra
warnings.

53 drivers are affected.  I checked the history of a bunch of them, and in
most cases, there have been only a handful of maintenance changes in the
last six months.  serial_core.c was the busiest one that I looked at.

38e2bfc94e USB: Dealias -110 code (more complete)
The purpose of this patch is to split off the case when a device does
not reply on the lower level (which is reported by HC hardware), and
a case when the device accepted the request, but does not reply at
upper level. This redefinition allows to diagnose issues easier,
without asking the user if the -110 happened "immediately".

The usbmon splits such cases already thanks to its timestamp, but
it's not always available.

I adjusted all drivers which I found affected (by searching for "urb").
Out of tree drivers may suffer a little bit, but I do not expect much
breakage. At worst they may print a few messages.

73a8881454 [PATCH] isdn4linux: Siemens Gigaset base driver: fix disconnect handling
Fix a possible Oops in the Siemens Gigaset base driver when the device is
unplugged while an ISDN connection is still active, and makes sure that the
isdn4linux link level (LL) is properly informed if a connection is broken
by the USB cable being unplugged.

- Avoid unsafe checks of URB status fields outside the URB completion
  handlers, keep track of in-use URBs myself instead.

- If an isochronous transfer URB completes with status==0, also check the
  status of the frame descriptors.

- Verify length of interrupt messages received from the device.

- Align the length limit on transmitted AT commands with the device
  documentation.

- In case of AT response receive overrun, keep newly arrived instead of old
  unread data.

- Remove redundant check of device ID in the USB probe function.

- Correct and improve some comments and formatting.

And: Tilman Schmidt <tilman@imap.cc>

This patch adds the procfs interface to the gigaset module.  The procfs
interface provides access to status information and statistics about the
Gigaset devices.  If the drivers are built with the debugging option it also
allows to change the amount of debugging output on the fly.

6fd5ea63f8 [PATCH] isdn4linux: Siemens Gigaset drivers - common module
And: Tilman Schmidt <tilman@imap.cc>

This patch adds the common include file for the Siemens Gigaset drivers,
providing definitions used by all of the Gigaset ISDN driver source files.  It
also adds the main source file of the gigaset module which manages common
functions not specific to the type of connection to the device.

0a34eb8f55 [PATCH] isdn4linux: Siemens Gigaset drivers - Kconfigs and Makefiles
And: Tilman Schmidt <tilman@imap.cc>

The following patches add drivers for the Siemens Gigaset 3070 family of ISDN
DECT PABXes connected via USB, either directly or over a DECT link using a
Gigaset M105 or compatible DECT data adapter.  The devices are integrated as
ISDN adapters within the isdn4linux framework, supporting incoming and
outgoing voice and data connections, and also as tty devices providing access
to device specific AT commands.

Supported devices include models 3070, 3075, 4170, 4175, SX205, SX255, and
SX353 from the Siemens Gigaset product family, as well as the technically
identical models 45isdn and 721X from the Deutsche Telekom Sinus series.
Supported DECT adapters are the Gigaset M105 data and the technically
identical Gigaset USB Adapter DECT, Sinus 45 data 2, and Sinus 721 data (but
not the Gigaset M34 and Sinus 702 data which advertise themselves as CDC-ACM
devices).

These drivers have been developed over the last four years within the
SourceForge project http://sourceforge.net/projects/gigaset307x/.  They are
being used successfully in several installations for dial-in Internet access
and for voice call switching with Asterisk.

This is our second attempt at submitting these drivers, taking into account
the comments we received to our first submission on 2005-12-11.

The patch set adds three kernel modules:

- a common module "gigaset" encapsulating the common logic for
  controlling the PABX and the interfaces to userspace and the
  isdn4linux subsystem.

- a connection-specific module "bas_gigaset" which handles
  communication with the PABX over a direct USB connection.

- a connection-specific module "usb_gigaset" which does the same
  for a DECT connection using the Gigaset M105 USB DECT adapter.

We also have a module "ser_gigaset" which supports the Gigaset M101 RS232 DECT
adapter, but we didn't judge it fit for inclusion in the kernel, as it does
direct programming of a i8250 serial port.  It should probably be rewritten as
a serial line discipline but so far we lack the neccessary knowledge about
writing a line discipline for that.

The drivers have been working with kernel releases 2.2 and 2.4 as well as 2.6,
and although we took efforts to remove the compatibility code for this
submission, it probably still shows in places.  Please make allowances.

This patch:

Prepare the kernel build infrastructure for addition of the Gigaset ISDN
drivers.  It creates a Makefile and Kconfig file for the Gigaset driver and
hooks them into those of the isdn4linux subsystem.  It also adds a MAINTAINERS
entry for the driver.

This patch depends on patches 2 to 9 of the present set, as without the actual
source files, activating the options added here will cause the kernel build to
fail.
