Subject[PATCH bpf-next] selftests/bpf: Fix build error for LoongArch
Date
There exists build error when make -C tools/testing/selftests/bpf/
on LoongArch:

BINARY test_verifier
In file included from test_verifier.c:27:
tools/include/uapi/linux/bpf_perf_event.h:14:28: error: field 'regs' has incomplete type
14 | bpf_user_pt_regs_t regs;
| ^~~~
make: *** [Makefile:577: tools/testing/selftests/bpf/test_verifier] Error 1
make: Leaving directory 'tools/testing/selftests/bpf'

Add missing uapi header for LoongArch to use the following definition:
typedef struct user_pt_regs bpf_user_pt_regs_t;
