4e32997205 isdn: rename capi_ctr_reseted() to capi_ctr_down()
Change the name of the Kernel CAPI exported function capi_ctr_reseted()
to something representing its purpose better.

Impact: renaming, no functional change

1c594c05a7 b1isa: fix b1isa_exit() to really remove registered capi controllers
On "/etc/init.d/capiutils stop", this oops happened.

The oops happens on reading /proc/capi/controllers because
capi_ctrl->procinfo is called for the wrongly not unregistered
controller, which points to b1isa_procinfo(), which was removed on
module unload.

b1isa_exit() did not call b1isa_remove() for its controllers because
io[0] == 0 on module unload despite having been 0x340 on module load.

Besides, just removing the controllers that where added on module
load time and not those that were added later via b1isa_add_card() is
wrong too - the place where all added cards are found is isa_dev[].

1ccfd63367 i4l: Fix random hard freeze with AVM c4 card
The patch
- Includes the call to capilib_data_b3_req in the spinlock. This routine
  in turn calls the offending mq_enqueue routine that triggered the
  freeze if not locked.  This should also fix other indicators of
  incosistent capilib_msgidqueue list, that trigger messages like:
  Oct  5 03:05:57 BERL0 kernel: kcapi: msgid 3019 ncci 0x30301 not on queue
  that we saw several times a day (usually several in a row).
- Fixes all occurrences of c4_dispatch_tx to be called with active
  spinlock, there were some instances where no lock was active. Mostly
  these are in very infrequently called routines, so the additional
  performance penalty is minimal.

cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

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.

0f6c10ead8 [PATCH] i4l make PCMCIA for all cards working with shared IRQ
most current laptops do not work without allowing shared cardbus IRQs.
This patch enables IRQ sharing, so these cards work again.
This was tested with shared and none shared cardbus IRQs on different laptops
without problems.

e2d4096365 [PATCH] pcmcia: use bitfield instead of p_state and state
Instead of the two status values struct pcmcia_device->p_state and state,
use descriptive bitfields. Most value-checking in drivers was invalid, as
the core now only calls the ->remove() (a.k.a. detach) function in case the
attachement _and_ configuration was successful.

15b99ac172 [PATCH] pcmcia: add return value to _config() functions
Most of the driver initialization isn't done in the .probe function, but in
the internal _config() functions. Make them return a value, so that .probe
can properly report whether the probing of the device succeeded or not.

f8cfa618dc [PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe callback
Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified
probe() callback. As all in-kernel drivers are changed to this new
callback, there will be no temporary backwards-compatibility. Inside a
probe() function, each driver _must_ set struct pcmcia_device
*p_dev->instance and instance->handle correctly.

With these patches, the basic driver interface for 16-bit PCMCIA drivers
now has the classic four callbacks known also from other buses:

        int (*probe)            (struct pcmcia_device *dev);
        void (*remove)          (struct pcmcia_device *dev);

        int (*suspend)          (struct pcmcia_device *dev);
        int (*resume)           (struct pcmcia_device *dev);

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
