At the moment the userfaultfd test program only supports x86 and an architecture called "powewrpc" ;-) Fix that typo and add the syscall numbers for other architectures as well. Also as in an ideal world a syscall number should come from the system header file <asm/unistd.h>, include that header and guard the explicit syscall number section below to avoid redefinitions.
