Andrii Nakryiko aadc10434c selftests/bpf: Don't rely on preserving volatile in PT_REGS macros in loop3 ... commit 70bc793382 upstream. PT_REGS*() macro on some architectures force-cast struct pt_regs to other types (user_pt_regs, etc) and might drop volatile modifiers, if any. Volatile isn't really required as pt_regs value isn't supposed to change during the BPF program run, so this is correct behavior. But progs/loop3.c relies on that volatile modifier to ensure that loop is preserved. Fix loop3.c by declaring i and sum variables as volatile instead. It preserves the loop and makes the test pass on all architectures (including s390x which is currently broken).
