The patch adds a check at the beginning of i2c_del_adapter in case
someone attempts to remove an adapter that was never added in the first
place. This sounds like a good safety, as doing so will lead to an oops
at the moment. Also, I have a need for it in the latest version of my
i2c-amd756-s4882 patch. I need to remove the original adapter and
install the virtual ones instead, but I have no way to know if the
original adapter was succesfully added beforehand or not.

This is my port of the pc87360 driver. It supports the hardware
monitoring functions of the National Semiconductor PC8736x Super-I/O
family. The PC87360, PC87363 and PC87364 only do fan monitoring and
control. The PC87365 and PC87366 additionally have voltage and
temperature monitoring.

The driver was ported upon request from Wincor-Nixdorf, and tested by
Rolf Müller there. I wish to thank Rolf for his very efficient
cooperation.

Please apply,
thanks.

The patch below removes an unused function from drivers/i2c/chips/it87.c
Signed-off-by: Adrian Bunk <bunk@stusta.de>
Signed-off-by: Greg Kroah-Hartman <greg@kroah.com>

This is a new I2C chip driver named lm63, which supports National
Semiconductor's LM63 hardware monitoring chip. The LM63 is similar to
the LM86 (which we do support through our lm90 driver) with additional
monitoring and control of a single fan. It is obviously aimed at the CPU
and high-end graphics adapters markets. This new driver is very similar
in nature to the lm83 and lm90 driver so I don't have much to add.

I developed the driver on a request from Hard Data Ltd. which are using
Tyan S4882 boards where four LM63 chips are used (one for each CPU).
Tyan provided remote access to a test system so that I could test my
driver on real LM63 chips.

Oh, well. I should have used wait_event_interruptible_timeout when I
ported this driver to 2.6.

This patch fixes recently introduced race and also cleans ups some
2.4-ism.

This didn't show up in my "allmodconfig" tests, because the
console requires things to be built-in, not modules.

Posix timers preallocate siqueue structures during timer creation
and keep them for reuse.  This allocation happens in user context
with no locks held, however it's designated as an atomic allocation.
Loosen this restriction, and while we're at it let's do a bit of code
consolidation so signal sending uses same __sigqueue_alloc() helper.

Registering a security module can be a noisy operation, esp. when it
retries registration with the primary module.  Eliminate some noise, and
distinguish the return values for register_security so a module can tell
the difference between failure modes.

trivial sound/parisc updates:

 - substream->dma_device was removed (Stuart Brady)
 - Fix module unloading (Stuart Brady)
 - Fixed the off-by-one in snd_card_harmony_rate_bits (Stuart Brady)
 - Harmony is a GSC device, not available on pure PCI machines (Matthew Wilcox)
 - Fixed module parameter descriptions for ALSA Harmony (Stuart Brady)

Currently they are in the generic setup, pretty confusing. This patch
moves the io scheduler selection into a seperate menu under block
devices.

When the generic IRQ stuff went in, it seems that HARDIRQ_BITS got bumped
from 9 (for ppc64) up to 12.  Consequently, the PREEMPT_ACTIVE bit is now
within HARDIRQ_MASK, and I get in_interrupt() falsely returning true when
PREEMPT_ACTIVE is set, and thus a BUG_ON tripping in arch/ppc64/mm/tlb.c.

The patch below fixes this by changing PREEMPT_ACTIVE to 0x10000000.  I
have changed the PREEMPT_ACTIVE definitions for each of the architectures
that define CONFIG_GENERIC_HARDIRQS (i386, ppc, ppc64, x86_64) and fixed
the comment in include/linux/hardirq.h.  We could perhaps move the
PREEMPT_ACTIVE definition to include/linux/hardirq.h - I don't know why it
is still per-arch.

The current "generic" implementation of IRQ probing isn't well suited
for ppc in it's current form, and causes issues with yenta_socket
(and possibly others) on pmac laptops. We didn't have a probe implementation
in the past, we probably don't need one anyway, so for now, the fix is to
make this optional and enable it on x86 and x86_64 but not ppc and ppc64
(the 4 archs to use the generic IRQ code).
