[PATCH v2 4/6] s390/uapi: correct whitespace & coding style in asm/ptrace.h

Correct whitespace and coding style issues in the s390 asm/ptrace.h uapi header file. This is preparatory work to copy it to the tools/ directory for inclusion by selftests and perf. Signed-off-by: Hendrik Brueckner --- arch/s390/include/uapi/asm/ptrace.h | 118

[PATCH v2 5/6] selftests/bpf: sync kernel headers and introduce arch support in Makefile

Synchronize the uapi kernel header files which solves the broken uapi export of pt_regs. Because of arch-specific uapi headers, extended the include path in the Makefile. With this change, the test_verifier program compiles and runs successfully on s390. Signed-off-by: Hendrik Brueckner
