Hi Deepak,
I got some errors when building this test, I suppose they should be
fixed in the next version.

riscv_cfi_test.c: In function 'sigsegv_handler':
riscv_cfi_test.c:17:28: error: 'SEGV_CPERR' undeclared (first use in
this function); did you mean 'SEGV_ACCERR'?

Did you run "make headers_install" prior to building kselftest to get
the current kernel's headers available for userspace builds?

Yes, I have run "make header" and "make header_install" before
building the kselftest. This error happens when I cross compiled it,
perhaps I can help to check if it is missing some header files or
header search path.
