Fix for bug #6395:
Fail to resume on Tecra M2 with ADM1032 and Intel 82801DBM
The BIOS of the Tecra M2 doesn't like it when it has to reboot or resume
after the i2c-i801 driver has left the SMBus in PEC mode. The most simple
fix is to clear the PEC bit after after every transaction. That's what
this driver was doing up to 2.6.15 (inclusive).
Thanks to Daniele Gaffuri for the very good report.

On the MSI-K8T-NEO2 FIR ( Athlon-64, Socket 939 with VIA-K8T800- Chipset
and onboard Sound,... ) the BIOS lets you choose "DISABLED" or "AUTO" for
the On-Board Sound Device.
If you add another PCI-Sound-Card the BIOS disables the on-board device.
So far I have a Quirk, that does set the correspondent BIT in the
PCI-registers to enable the soundcard.
But how to ensure that the code is executed ONLY on excactly this kind of
boards (not any other with similar Chipset)?

During module unloading, cdev_del() must be called to unmap cdev related
kobject references and other cleanups(such as inode->i_cdev being set to
NULL) which prevents the OOPS upon subsequent loading, usage and unloading
of modules(as seen in the mail thread
http://marc.theaimsgroup.com/?l=linux-kernel&m=114533640609018&w=2).
Also, remove unneeded test of gpio_base.

In cases where a struct kretprobe's *_handler fields are non-NULL, it is
possible to cause a system crash, due to the possibility of calls ending up
in zombie functions. Documentation clearly states that unused *_handlers
should be set to NULL, but kprobe users sometimes fail to do so.
Fix it by setting the non-relevant fields of the struct kretprobe to NULL.

I was sloppy when generating a previous patch; I modified the callers of
krb5_make_checksum() to allocate memory for the buffer where the result is
returned, then forgot to modify krb5_make_checksum to stop allocating that
memory itself. The result is a per-packet memory leak. This fixes the
problem by removing the now-superfluous kmalloc().

The alim15x3.c havn't been update for 3 years. Recently when we use this
"ULI M1573" south bridge chip found that can't mount CDROM(VCD) smoothly,
must waiting for a long time. After I check the "ULI M1573" south bridge
datasheet, I found the reason. The reason is the "ULI M1573" version in
the Linux is "0xC7" not "0xC4" anymore So I was modified the source than it
was successed.

return -1;
...
memcpy(bt->write_data + 3, data + 1, size - 1);
where sizeof bt->write_data is IPMI_MAX_MSG_LENGTH. It looks like the
memcpy would overflow by 2 bytes if size == IPMI_MAX_MSG_LENGTH. A patch

I think this is fine. It seems to me that this may be the fault of one or
both of the APM solutions handling this situation in a non-standard way, but
since APM is used very little on the Geode, and I have direct access to our

DEBUG_MUTEX flag is on by default in current kernel configuration.
During performance testing, we saw mutex debug functions like
mutex_debug_check_no_locks_freed (called by kfree()) is expensive as it
goes through a global list of memory areas with mutex lock and do the
checking. For benchmarks such as Volanomark and Hackbench, we have seen
more than 40% drop in performance on some platforms. We suggest to set
DEBUG_MUTEX off by default. Or at least do that later when we feel that
the mutex changes in the current code have stabilized.

There are places in the kernel where we look up files in fd tables and
access the file structure without holding refereces to the file. So, we
need special care to avoid the race between looking up files in the fd
table and tearing down of the file in another CPU. Otherwise, one might
see a NULL f_dentry or such torn down version of the file. This patch
fixes those special places where such a race may happen.

We were missing __volatile__ on some bits of asm in the segfault handlers.
On x86_64, this was messing up the move from %rdx to uc because that was
moved to after the GET_FAULTINFO_FROM_SC, which changed %rdx.
Also changed the other bit of asm and the one in the i386 handler to
