Hendrik Brueckner c682ccc496 bpf: fix broken BPF selftest build on s390 ... With 720f228e8d ("bpf: fix broken BPF selftest build") the inclusion of arch-specific header files changed. Including the asm/bpf_perf_event.h on s390, correctly includes the s390 specific header file. This header file tries then to include the s390 asm/ptrace.h and the build fails with: cc -Wall -O2 -I../../../include/uapi -I../../../lib -I../../../../include/generated -I../../../include test_verifier.c +/root/git/linux/tools/testing/selftests/bpf/libbpf.a /root/git/linux/tools/testing/selftests/bpf/cgroup_helpers.c -lcap -lelf -o +/root/git/linux/tools/testing/selftests/bpf/test_verifier In file included from ../../../include/uapi/asm/bpf_perf_event.h:4:0, from ../../../include/uapi/linux/bpf_perf_event.h:11, from test_verifier.c:29: ../../../include/uapi/../../arch/s390/include/uapi/asm/bpf_perf_event.h:7:9: error: unknown type name 'user_pt_regs' typedef user_pt_regs bpf_user_pt_regs_t; ^~~~~~~~~~~~ make: *** [../lib.mk:109: /root/git/linux/tools/testing/selftests/bpf/test_verifier] Error 1 This is caused by a recent update to the s390 asm/ptrace.h file that is not (yet) available in the local installation. That means, the s390 asm/ptrace.h must be included from the tools/arch/s390 directory. Because there is no proper framework to deal with asm specific includes in tools/, slightly modify the s390 asm/bpf_perf_event.h to include the local ptrace.h header file. See also discussion on https://marc.info/?l=linux-s390&m=151359424420691&w=2 Please note that this needs to be preserved until tools/ is able to correctly handle asm specific headers.
