+Subject: arch/tile: avoid generating .eh_frame information in modules
+
+From: Chris Metcalf <cmetcalf@tilera.com>
+
+commit 627072b06c362bbe7dc256f618aaa63351f0cfe6 upstream.
+
+The tile tool chain uses the .eh_frame information for backtracing.
+The vmlinux build drops any .eh_frame sections at link time, but when
+present in kernel modules, it causes a module load failure due to the
+presence of unsupported pc-relative relocations.  When compiling to
+use compiler feedback support, the compiler by default omits .eh_frame
+information, so we don't see this problem.  But when not using feedback,
+we need to explicitly suppress the .eh_frame.
