selftests: Test RISC-V Vector's first-use handler This add a test to check if the kernel zero-initializes all V registers after the first-use trap handler returns. If V registers are not zero-initialized, then the test should fail one out of several runs: root@sifive-fpga:~# ./v_initval_nolibc # vl = 256 not ok 1 detect stale values on v-regesters 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 4c 41 4e 47 3d 43 0 50 41 54 48 3d 2f 75 73 72 2f 6c 6f 63 61 6c 2f 73 62 69 6e 3a 2f 75 73 72 2f 6c 6f 63 61 6c 2f 62 69 6e 3a 2f 75 73 72 ff ff 81 0 0 0 0 0 0 0 0 0 0 0 0 0 Otherwise, the test passes without errors each run.

tools: selftests: riscv: Fix compile warnings in vector tests [ Upstream commit e1baf5e68ed128c1e22ba43e5190526d85de323c ] GCC prints a couple of format string warnings when compiling the vector tests. Let's follow the recommendation in Documentation/printk-formats.txt to fix these warnings.

selftests: riscv: Fix compilation error with vstate_exec_nolibc.c The following error happens: In file included from vstate_exec_nolibc.c:2: /usr/include/riscv64-linux-gnu/sys/prctl.h:42:12: error: conflicting types for ‘prctl’; h ave ‘int(int, ...)’ 42 | extern int prctl (int __option, ...) __THROW; | ^~~~~ In file included from ./../../../../include/nolibc/nolibc.h:99, from <command-line>: ./../../../../include/nolibc/sys.h:892:5: note: previous definition of ‘prctl’ with type ‘int(int, long unsigned int, long unsigned int, long unsigned int, long unsigned int) ’ 892 | int prctl(int option, unsigned long arg2, unsigned long arg3, | ^~~~~ Fix this by not including <sys/prctl.h>, which is not needed here since prctl syscall is directly called using its number.
