3.13.11-ckt30 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Will Deacon <will.deacon at arm.com>
commit b6dd8e0719c0d2d01429639a11b7bc2677de240c upstream.
Commit df057cc7b4fa ("arm64: errata: add module build workaround for
erratum #843419") sets CFLAGS_MODULE to ensure that the large memory
model is used by the compiler when building kernel modules.
However, CFLAGS_MODULE is an environment variable and intended to be
overridden on the command line, which appears to be the case with the
Ubuntu kernel packaging system, so use KBUILD_CFLAGS_MODULE instead.
