rt-setup and rt-tests enhancement update

Updated packages that add enhancements are now available for Red Hat
Enterprise MRG 1.1.

This update is for the following packages:

* rt-tests is a set of programs that test and measure various components of
real-time kernel behavior. Measures include timer latency, signal latency,
hardware latency and the functioning of priority-inheritance mutexes.

* rt-setup configures settings required by the Red Hat Enterprise Linux
realtime environment, such as creating the realtime group, adding realtime
user privileges to PAM (Pluggable Authentication Models), enabling the
configuration of kdump in realtime, and disabling irqbalance by default.

These updated packages add the following enhancements:

* the rt-tests module was added to the hwlatdetect script. This is to allow
access to the hardware latency detector module delivered in RT kernels (BZ
#512213)

These updated packages fix the following bugs:

* the real-time clock was unable to be opened. This was caused by an
incorrect udev rule. The rule was fixed, and the real-time clock now opens
as expected (BZ #510121)

* the nice value specified in the limits.d/realtime.conf file was set to a
value outside the valid range. This default value has now been changed so
to a valid value (BZ #479228)

Users of the Realtime capabilities of Red Hat Enterprise MRG are advised
to upgrade to these updated rt-setup and rt-tests packages, which add these
enhancements.

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

This update is available via Red Hat Network. Details on how to use
