O-Subject: [RHEL5.4 PATCH 1/2] Revert kernel fix for LUKS passphrase
Bugzilla: 475986
RH-Acked-by: Chris Lalancette <clalance@redhat.com>

Fixes bz 475986
https://bugzilla.redhat.com/show_bug.cgi?id=475986

This part of the patch is a request to remove the
following patch from the kernel spec file:

Patch23454: linux-2.6-xen-console-make-luks-passphrase-readable.patch

The problem we fixed in the kernel has been fixed upstream
in the hypervisor. This reverts the kernel fix and the
next patch supplies the hypervisor fix.
