Applied the first 23 patches, since patch 24 failed to apply to bpf and bpf-next trees. selftest/bpf/test_progs shows that all bpf trampoline tests are failing and eventually the kernel is crashing: [ 53.040582] RIP: 0010:do_init_module+0x9/0x6f0 [ 53.052044] Call Trace: [ 53.052319] <TASK> [ 53.052559] bpf_trampoline_6442471381_0+0x32/0x1000 [ 53.053117] do_init_module+0x5/0x6f0 [ 53.053550] load_module+0x77c0/0x9c00 I havne't had time to debug what's going on.
