    Hmm, with those two patches on I get:

    root@tigerlake:/usr/src/linux-2.6/tgl-build# ./test_progs -t fexit
    #46 fentry_fexit:OK
    #48 fexit_bpf2bpf:OK
    #49 fexit_sleep:OK
    #50 fexit_stress:OK
    #51 fexit_test:OK
    Summary: 5/9 PASSED, 0 SKIPPED, 0 FAILED

    On the tigerlake, I suppose I'm doing something wrong on the other
    machine because there it's even failing on the pre-ibt kernel image.

    I'll go write up changelogs and stick these on.
