* Pull three interdependent patches from Debian to fix AVX detection problems on kernels or CPUs that lack support for it (LP: #979003): - amd64/cvs-avx-detection.diff: Improved detection on old kernels. - amd64/cvs-dl_trampoline-cfi.diff: fix CFI in dl_trampoline code. - amd64/cvs-avx-osxsave.diff: Disable AVX without OSXAVE support. * Also backport amd64/submitted-tst-audit6-avx.diff from oneiric to skip tests if AVX extensions are not available on the build host. * Use non-deprecated --reject-format=unified QUILT_PATCH_OPTS option.
