kexec-tools bug fix update

An updated kexec-tools package that fixes two bugs is now available for Red Hat
Enterprise Linux 6.

The kexec-tools package contains the /sbin/kexec binary and utilities that
together form the user-space component of the kernel's kexec feature. The
/sbin/kexec binary facilitates a new kernel to boot using the kernel's kexec
feature either on a normal or a panic reboot. The kexec fastboot mechanism
allows booting a Linux kernel from the context of an already running kernel.

This update fixes for the following bugs:

* Previously, the mkdumprd utility failed to parse the /etc/mdadm.cof
configuration file. As a consequence, mkdumprd failed to create an initial
ramdisk for kdump crash recovery and the kdump service failed to start. With
this update, mkdumprd has been modified so that it now parses the configuration
file and builds initrd correctly. The kdump service now starts as expected.
(BZ#719917)

* On the PowerPC 64 architecture, the kexec utiliity experienced a segmentation
fault when the kdump service was started on a system containing more than 1 TB
of RAM. As a result, it was not possible to capture a crash kernel on such a
system. This has been fixed with this update so that kexec no longer crashes
when kdump starts on a system with greater than 1 TB of physical memory, and
kdump can now works as expected. (BZ#726603)

All users of kexec-tools are advised to upgrade to this updated package, which
fixes these bugs.

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