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

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.
