------------------------------------------------------
Subject: /proc/kallsyms reports lower-case types for some non-exported symbols
From: Adam B. Jerome <abj@xxxxxxxxxx>
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
