The attached patch fixes the unaligned display on serial console that has
occurred due to non-printable characters being inserted on the ramdump and
bootlog screens of coreinfo.

-------------- next part --------------
Do not try to display non-printable characters on the bootlog and
ramdump screens. This fixes unaligned display on serial console.
The current isprint() implementation assumes a C locale, so also
characters with the eigth bit set are supressed (they produced
inconsistant results on VGA and serial anyway).
