Subject: [PATCH 8/8] pmcraid: Pass pointers to access_ok(), not integers

Most architectures define access_ok() as a macro that casts its
argument such that an argument of type unsigned long will be accepted
without complaint.  However, the proper type is void *, and passing
unsigned long results in a warning on sparc64.
