sys_timer_settime returns EINVAL if *new is NULL, compat_timer_settime
returns EFAULT.  Add a check to compat_timer_settime to return EINVAL
if *new is NULL.

Common i/o layer fixes:
 - Add atomic onoff variable to ccw devices and ccw-group devices to
   avoid races during online/offline.
 - Fix pr_debug calls.
 - A lot of path fixes:
   + Set device to disconnected state after no path event.
   + Fix chpid vary on/off for single path devices.
   + Make logical vary on/off consistent with physical vary on/off.
   + Don't update subchannel schib if the device is gone (dnv not set).
   + Add code to recover lost chpids after machine checks.
   + Avoid processing link incidents, resource accessability events and
     chpid machine checks for logically offline chpids.
   + Recover disconnected devices after chsc machine checks.
   + Delay de-registering of no path devices to avoid deadlocks.
   + Don't redo ssd for known subchannels - the info is static.
   + Introduce a second, "slow" machine check handler thread for new devices.
     The "fast" machine check handler only recovers disconnected devices.
 - Deregister subchannel rather than ccw device on not oper events.
 - Fix calling sequence of notify function vs. path verification.
 - Reset timeout for disconnected devices.
 - Fix problem with debug feature and %s arguments.

 - Handle call to the io_subchannel remove function if the ccw device
   is not registered yet.
 - Add availability attribute for ccw devices: "good", "no device",
   "no path", "boxed".
 - Export ccw_device_work for qdio as module.
 - Retry sense id for tape devices which present intervention required.
 - Don't check the activity control to decide if the device driver interrupt
   handler needs to be called but use the bits in status control.
 - Fix race in ccw_device_stlck.
 - Accumulate deferred condition code.
 - Fix setting_up_sema locking.
 - Call qdio_shutdown instead of qdio_cleanup on failed establish.

 - Remove _exit definition from unistd.h.

From: Christoph Hellwig <hch@lst.de>

Take a reference before calling into the module and release it after we're
done.  Also remove the useless (and wrong) refcounting in videocodec -
symbols from this module are used by other modules if we call into those
functions so it can't be unloaded anyway.

We really need to add a debug check to tip all those
try_module_get(THIS_MODULE) callers..

This driver adds full read/write support for HFS+ and is based on the
readonly driver by Brad Broyer.

Thanks to Ethan Benson <erbenson@alaska.net> for a number of patches to
make the driver more compliant with the spec.

From: Roman Zippel <zippel@linux-m68k.org>

This is a complete rewrite of the HFS driver, it gets rid of a all the
special conversion options, which belong in user space.  The driver uses now
a btree support very similiar to HFS+, so that both could be merged at some
point.

Thanks to Ethan Benson <erbenson@alaska.net> for a number of patches to make
the driver more compliant with the spec and Christoph Hellwig <hch@lst.de>
for fixing up the documentation.

Zorro8390 Ethernet: Convert to the new driver model

For some unknown reasons Nvidia NForce3 doesn't use the standard Hammer AGP architecture,
but requires set up of some shadow registers. This patch adds that to the K8 AGP driver.

Based on an old 2.4 patch from someone at Nvidia.

Also includes another bug fix for the K8 AGP handler, from Brad House.
We should not assume that there is only one northbridge in a Uniprocessor system.
Always flush all.

Also some minor cleanup.

Give 32bit emulation ioctl handlers the same locking rules as normal ioctl handlers.
This will avoid surprises in driver code.

Most call sys_ioctl who would take it anyways.

This adds a new completely rewritten machine check handler for x86-64.
The old one never worked on 2.6.

The new handler has many improvements. It closely follows the Intel and AMD
recommendations on MCE handlers now (the old one had many violations). It handles
unrecoverable errors in user space better now - it will only kill the process now
if possible instead of panicing.

This one is CPU independent now - it should work on any CPU that supports the standard
x86 MCA architecture.

This new handler only logs fatal errors that lead to kernel panic to the console.
Non fatal errors are logged race free into a new (non ring) buffer now
and supplied to the user using a new character device.  The old one could
deadlock on console and printk locks. This also separates machine check errors
from real kernel errors better. The new buffer has been also designed to
be easily accessible from external debugging tools: it has a signature
and could be even recovered after reboot. It is not organized as a ring buffer -
this means the first errors are kept unless explicitely cleared.

The new error formats can be parsed using ftp://ftp.suse.com/pub/people/ak/x86-64/mcelog.c
The new character device for it can be created with mknod /dev/mcelog c 10 227

There is a new sysfs interface to configure the machine check handler.
It has a "tolerant" parameter that defines the aggressiveness of the machine check:

0: always panic
1: panic if deadlock possible (e.g. MCE happened in the kernel)
2: try to avoid panic

Default is 2

Despite of having more features the new handler is shorter.

Bring the x86-64 port up to date. Lots of smaller bug fixes that have accumulated.
Also fixes another nasty bug introduced by the IA32e changes that causes BUGs at
boot for some people.

Only changes x86-64 specific files. There are some other changes that I'm sending

From: Andreas Gruenbacher <agruen@suse.de>,
      and me.

Latest gcc cvs is able to detect mismatches between functions which are
tagged asmlinkage and declarations which are missing asmlinkage.  Or vice
versa.

Fix up the fallout from an x86 allyesconfig build.

From: "Randy.Dunlap" <rddunlap@osdl.org>

Add syscalls.h, which contains prototypes for the kernel's system calls.
Replace open-coded declarations all over the place.  This patch found a
couple of prior bugs.  It appears to be more important with -mregparm=3 as we
discover more asmlinkage mismatches.

Some syscalls have arch-dependent arguments, so their prototypes are in the
arch-specific unistd.h.  Maybe it should have been asm/syscalls.h, but there
were already arch-specific syscall prototypes in asm/unistd.h...

Tested on x86, ia64, x86_64, ppc64, s390 and sparc64.  May cause
trivial-to-fix build breakage on other architectures.

swsusp/s3 assembly parts, and parts called from assembly are not properly

ENOTSUPP is the wrong value, and should not be returned to userspace.
