Subject: [bpf] a162f637b0: kernel-selftests.bpf.test_align.fail

FYI, we noticed the following commit (built with gcc-7):

commit: a162f637b08577f8e843d469ec20b338853e05ca ("[RFC PATCH 2/4] bpf: verifier, do explicit u32 bounds tracking")
url: https://github.com/0day-ci/linux/commits/John-Fastabend/rfc-for-32-bit-subreg-verifier-tracking/20200307-081430
base: https://git.kernel.org/cgit/linux/kernel/git/bpf/bpf.git master

in testcase: kernel-selftests
with following parameters:

	group: kselftests-bpf
	ucode: 0xd6

test-description: The kernel contains a set of "self tests" under the tools/testing/selftests/ directory. These are intended to be small unit tests to exercise individual code paths in the kernel.
test-url: https://www.kernel.org/doc/Documentation/kselftest.txt


on test machine: 8 threads Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz with 16G memory
