Subject[PATCH] kallsyms: report consistent types for non-exported symbols
From: Adam B. Jerome <abj@novell.com>

This patch addresses incorrect symbol type information reported through /proc/kallsyms.
A lowercase character should designate the symbol as local (or non-exported). An
uppercase character should designate the symbol as global (or external). Without this
patch, some non-exported symbols are incorrectly assigned an upper-case designation in
/proc/kallsyms. This patch corrects this condition by converting non-exported symbols
types to lower case when appropriate and eliminates the superfluous upcase_if_global
function.

Please apply.
