    Subject[PATCH 24/26] dynamic_debug: reduce lineno field to a saner 18 bits
    Date
    From: Jim Cromie <jim.cromie@gmail.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.
