[PATCH] ix86: in kernel context print control and debugregisters too

[Jan Beulich]

While for a user mode register dump it may be reasonable to skip those
(albeit x86-64 doesn't do so), for kernel mode dumps these should be
printed to make sure all information possibly necessary for analysis is
available.
