Subject: [PATCH 3.12 070/118] x86, build, icc: Remove uninitialized_var() from compiler-intel.h

3.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "H. Peter Anvin" <hpa@...ux.intel.com>

commit 503cf95c061a0551eb684da364509297efbe55d9 upstream.

When compiling with icc, <linux/compiler-gcc.h> ends up included
because the icc environment defines __GNUC__.  Thus, we neither need
nor want to have this macro defined in both compiler-gcc.h and
compiler-intel.h, and the fact that they are inconsistent just makes
the compiler spew warnings.
