Subject: [PATCH 5.10 27/30] bpf, selftests: Adjust few selftest result_unpriv outcomes

From: Daniel Borkmann <daniel@...earbox.net>

commit 1bad6fd52be4ce12d207e2820ceb0f29ab31fc53 upstream

Given we don't need to simulate the speculative domain for registers with
immediates anymore since the verifier uses direct imm-based rewrites instead
of having to mask, we can also lift a few cases that were previously rejected.
