New Revision: 197789
URL: http://svn.freebsd.org/changeset/base/197789

Log:
  Fix NFSv4 ACLs on sparc64.  Turns out that fuword(9) fetches 64 bits
  instead of sizeof(int), and on sparc64 that resulted in fetching wrong
  value for acl_maxcnt, which in turn caused __acl_get_link(2) to fail
  with EINVAL.
