From bcea6aa8f288da7cb385e0ae2420e1b128ad0b52 Mon Sep 17 00:00:00 2001 From: Otavio Salvador Date: Wed, 18 Sep 2013 10:51:04 -0300 Subject: [PATCH] perf: Add LDFLAGS to allow build of old kernels without patching The LDFLAGS is required or some old kernels fails due missing symbols and this is preferred than requiring patches to every old supported kernel.
