Subject: selftests: riscv: vstate_exec_nolibc: Use the regular prctl() function
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=098921ec6818291d98bd3a4002c9dfbe2e75aac2;p=thirdparty%2Flinux.git

selftests: riscv: vstate_exec_nolibc: Use the regular prctl() function

The my_syscall*() macros are internal implementation details of nolibc.

Now that nolibc has a normal prctl() function, use that.
