Jean-Philippe Brucker	3a029e1f3d	selftests/bpf: Fix build of task_pt_regs test for arm64 ... struct pt_regs is not exported to userspace on all archs. arm64 and s390 export "user_pt_regs" instead, which causes build failure at the moment: progs/test_task_pt_regs.c:8:16: error: variable has incomplete type 'struct pt_regs' struct pt_regs current_regs = {}; Instead of using pt_regs from ptrace.h, use the larger kernel struct from vmlinux.h directly. Since the test runner task_pt_regs.c does not have access to the kernel struct definition, copy it into a char array.

Daniel Xu	576d47bb1a	bpf: selftests: Add bpf_task_pt_regs() selftest ... This test retrieves the uprobe's pt_regs in two different ways and compares the contents in an arch-agnostic way.
