On powerpc, a call to a VDSO function is not a standard C function call. Unlike x86 that returns a negated error code in case of an error, powerpc sets CR[SO] and returns the error code as a positive value.
So use a macro called VDSO_CALL() which takes a pointer to the function to call, the number of arguments and the arguments.
You'll probably want to move to VDSO_CALL() for the whole test suite, not just the getrandom one, right?
Yes indeed, the following needs it as well:
vdso_test_abi.c vdso_test_getcpu.c vdso_test_gettimeofday.c vdso_test_correctness.c
