Alexei Starovoitov 52d29b4783 bpf: Unbreak BPF_PROG_TYPE_KPROBE when kprobe is called via do_int3 ... [ Upstream commit 548f1191d86ccb9bde2a5305988877b7584c01eb ] The commit 0d00449c7a ("x86: Replace ist_enter() with nmi_enter()") converted do_int3 handler to be "NMI-like". That made old if (in_nmi()) check abort execution of bpf programs attached to kprobe when kprobe is firing via int3 (For example when kprobe is placed in the middle of the function). Remove the check to restore user visible behavior.
