      ssize_t process_madvise(int pidfd, const struct iovec *iovec,
                unsigned long vlen, int advice, unsigned int flags);

size_t for vlen provides a clearer hint regarding the type of special
treatment needed for ILP32 here (zero extension, not changing the type
to long long).

All existing system calls using iove in Linux uses unsigned long so
I want to be consistent with them unless process_madvise need something
speicial.

Userspace uses int, following POSIX (where applicable).  There is no
consistency to be had here.
