Subject: [PATCH 12/25] dynamic_debug: reduce lineno field to a saner 18 bits

From: Jim Cromie <jim.cromie@...il.com>

lineno:24 allows files with 4 million lines, an insane file-size, even
for never-to-get-in-tree machine generated code.  Reduce this to 18
bits, which still allows 256k lines.  This is still insanely big, but
its not raving mad.
