bpf: fix build issues on um due to mising bpf_perf_event.h

borkmann · Alexei Starovoitov · commit a23f06f06dbe · 2017-12-12T09:51:12.000-08:00
Since c895f6f ("bpf: correct broken uapi for BPF_PROG_TYPE_PERF_EVENT program type") um (uml) won't build on i386 or x86_64: [...] CC init/main.o In file included from ../include/linux/perf_event.h:18:0, from ../include/linux/trace_events.h:10, from ../include/trace/syscall.h:7, from ../include/linux/syscalls.h:82, from ../init/main.c:20: ../include/uapi/linux/bpf_perf_event.h:11:32: fatal error: asm/bpf_perf_event.h: No such file or directory #include <asm/bpf_perf_event.h> [...] Lets add missing bpf_perf_event.h also to um arch. This seems to be the only one still missing.
