[patch 3/3] Have kernel-PAE.i686 and kernel.x86_64 fix DEFAULTKERNEL=kernel-xen

[Mark McLoughlin]

plain text document attachment (kernel-xen-defaultkernel.patch)
Now we can fix:

  https://bugzilla.redhat.com/456558

by having kernel.x86_64 and kernel-PAE.i686 munge DEFAULTKERNEL
as appropriate.

Use sed --regexp-extended so we don't have to do "\(foo\|bar\)"
