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.

Alexey Dobriyan 99f932f026 [PATCH] CONFIG_PM=n slim: sound/oss/cs46xx.c
Remove some code which is unneeded if CONFIG_PM=n.

* Make suspend/resume registration look like the rest of drivers:
  #ifdef CONFIG_PM in struct pci_driver, prototypes, actual hooks.
* Drop CS46XX_ACPI_SUPPORT. It logically duplicated CONFIG_PM. It was
  hardcoded to 1 approx forever (ALSA merge just moved driver to
  sound/oss/).
* After previous point, sound/oss/cs46xxpm-24.h removed as being useless.
* As side effect selling (unused) static inline functions as suspend/resume
  hooks funkiness removed too.

Jesper Juhl 2eebb1925d [PATCH] OSS: cs46xx cleanup and tiny bugfix
Here's a patch for cs46xx that
 - (mostly) cleans up the cs46xx driver according to CodingStyle
 - removes a bunch of pointless casts
 - fixes a small, potential use of uninitialized variable, bug
 - reduces the size of the compiled code by 36 bytes
 - reduces the size of the source file by 1831 bytes

I know I should probably have split this into bits, but since I only
thought of that *after* doing all the edits, splitting it up would have
been a royal pain. And since these are all pretty trivial changes I thought
I'd just submit the one huge patch and hope people could live with it (if
not, then just tell me and I'll split it).

The bug fix that's in there may be hard to spot, so I'll point it out. It's
the
   -       int val, valsave, mapped, ret;
   +       int val, valsave, ret;
   +       int mapped = 0;
bit.
Without that change we may use `mapped' uninitialized if, in cs_ioctl, the
first test of "if(state)" is false and the second "if(state)" test is true.

Patrick Mochel 94661e7c33 [PATCH] oss: remove deprecated PM interface from cs46xx driver
This change removes the old, deprecated interface from the cs46xx driver,
including the pm_{,un}register() calls, the local storage of the pmdev object
and the reference to the old header files.  This change is done to assist in
eradicating the users of the legacy interface so as to help facilitate the
removal of the interface itself.

Note this driver has PCI PM hooks which are set properly.  It also has the
ability to trigger suspend/resume from an ioctl.  This functionality was not
touched, though it could use a serious review if this driver continues to
persist in the mainline tree..

Note that this driver has been obsoleted by an ALSA equivalent.

Linus Torvalds 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!
