kernel-utils bug fix and enhancement update

An updated kernel-utils package that fixes various bugs and adds
enhancements is now available.

The kernel-utils package provides kernel-related support utilities, such as
CPU frequency scaling support, and processor microcode updates.

This updated package fixes the following bugs:

* the "cpuspeed" daemon process was not aware of multi-core processors
sharing the same clock. One or more cores could end up without all
available frequency steppings, due to another core altering the frequency
during stepping detection.

* the irqbalance init script returned incorrect error codes, which may have
caused the wrong status to be returned. In this updated package, the init
script has been updated to more closely conform to distribution-wide
guidelines.

* in certain situations, using the "smartctl" command to enable S.M.A.R.T.
automatic offline data collection, failed with a "HSM violation" error in
"/var/log/messages", and the following errors on the console:

Error SMART Enable Automatic Offline failed: Input/output error
Smartctl: SMART Enable Automatic Offline Failed.

* the new microcode requires changes that are not in earlier kernels. When
running an older kernel and using a newer kernel-utils package, starting
the "microcode_ctl" service may have caused a "microcode: not enough data"
error. In this updated package, two microcode images are shipped: one for
older kernels, and the other for newer kernels, allowing users running
older kernels, or both new and old kernels, to obtain microcode updates.

As well, this updated package adds the following enhancements:

* processor frequency scaling support (powersave), using modular (rather
than built-in) powernow-k8 drivers, for AMD 64-bit-capable processors that
support AMD PowerNow!™, has been enabled.

* support for S.M.A.R.T. monitoring for 3ware RAID controllers, that have
more than 16 ports, has been added.

* to support the latest processors, the Intel microcode has been updated to
version 20080401.

Users of kernel-utils are advised to upgrade to this updated package, which
resolves these issues and adds these enhancements.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
