[PATCH 4.19 0/2] bpf: fix test_verifier, test_align selftests

[Ovidiu Panait <ovidiu.panait@windriver.com>]

Backport of upstream commits [1] and [2] to 4.19-stable broke test_verifier and
test_align bpf selftests.
[1] 2fa7d94afc1a ("bpf: Fix the off-by-two error in range markings")
[2] 294f2fc6da27 ("bpf: Verifer, adjust_scalar_min_max_vals to always call
                   update_reg_bounds()")

This series fixes all failing test_verifier/test_align testcases for 4.19:

#665/p mov64 src != dst OK
#666/u calls: ctx read at start of subprog OK
