vfs_rename_other() does not lock renamed inode with i_mutex. Thus changing
i_nlink in a non-atomic manner (which happens in ext2_rename()) can corrupt
it as reported and analyzed by Josh.

In fact, there is no good reason to mess with i_nlink of the moved file.
We did it presumably to simulate linking into the new directory and unlinking
from an old one. But the practical effect of this is disputable because fsck
can possibly treat file as being properly linked into both directories without
writing any error which is confusing. So we just stop increment-decrement
games with i_nlink which also fixes the corruption.

suspend and resume when it is. If the CODEC has suspended then it'll

cpufreq_register_driver sets cpufreq_driver to a structure owned (and
placed) in the caller's memory. If cpufreq policy fails in its ->init
function, sysdev_driver_register returns nonzero in
cpufreq_register_driver. Now, cpufreq_register_driver returns an error
without setting cpufreq_driver back to NULL.

Usually cpufreq policy modules are unloaded because they propagate the
error to the module init function and return that.

So a later access to any member of cpufreq_driver causes bugs like:

It appears that when powernow-k8 finds that

    No compatible ACPI _PSS objects found.

 and suggests

    Try again with latest BIOS.

 it fails the module load, but does not unregister the cpu_notifier that was
 registered in powernowk8_init

 This ends up leaving freed memory on the cpu notifier list for some other
 poor module (e.g. md/raid5) to come along and trip over.

 The following might be a partial fix, but I suspect there is probably other
 clean-up that is needed.

This reverts commit c4ff4b82.

 "TPM is working for me so I can log into employer's network in 2.6.37.
  It broke when I tried 2.6.38-rc6, with the following relevant lines
  from my dmesg:

  [   11.081627] tpm_tis 00:0b: 1.2 TPM (device-id 0x0, rev-id 78)

  [   78.040949] tpm_tis 00:0b: Operation Timed out

  This caused me to get suspicious, especially since the _other_ TPM
  commit in 2.6.38 had already been reverted, so I tried reverting
  commit c4ff4b82: "TPM: Long default timeout fix".  With this commit
  reverted, my TPM on my Lenovo T410 is once again working."

Several ACPI drivers fail to build if CONFIG_NET is unset, because
they refer to things depending on CONFIG_THERMAL that in turn depends
on CONFIG_NET.  However, CONFIG_THERMAL doesn't really need to depend
on CONFIG_NET, because the only part of it requiring CONFIG_NET is
the netlink interface in thermal_sys.c.

Put the netlink interface in thermal_sys.c under #ifdef CONFIG_NET
and remove the dependency of CONFIG_THERMAL on CONFIG_NET from
drivers/thermal/Kconfig.
