Subject: sparc64: make string buffers large enough
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit b5c3206190f1fddd100b3060eb15f0d775ffeab8 upstream.
My static checker complains that if "lvl" is ULONG_MAX (this is 64 bit)
then some of the strings will overflow. I don't know if that's possible
but it seems simple enough to make the buffers slightly larger.
