The overflow will be avoided on any boards that don't define
CONFIG_DEPRECATED_SILENT_LINUX_CONSOLE.  As of the third version of
this patch (will be sent shortly), the Blackfin board will be fixed so
that the overflow can't happen on that board.

With the third version of this patch the Blackfin board is one example
of a board that is fixed.  On all other boards, no functionality is
lost and no bugs are fixed.


Previously I had submitted a patch to fix the overflow itself, which
you NAKed (saying that fixup_silent_linux() was deprecated and
shouldn't get any bugfixes).  I am happy to dig that up and re-post it
if you'd prefer.  Either option is fine with me.

My problem is that I have a board that would like to use
CONFIG_SILENT_CONSOLE (to silence the U-Boot console) and have a Linux
command line that is >256 characters.  I either need the overflow
fixed (my previous patch) or some way to avoid it (this patch).


Thanks much!
