hppfs_read_file() may return (ssize_t) -ENOMEM, or -EFAULT. When stored
in size_t 'count', these errors will not be noticed, a large value will be
added to *ppos.

Attach creds to file structs and discard f_uid/f_gid.
file_operations::open() methods (such as hppfs_open()) should use file->f_cred
rather than current_cred(). At the moment file->f_cred will be current_cred()
at this point.

Pass credentials through dentry_open() so that the COW creds patch can have
SELinux's flush_unauthorized_files() pass the appropriate creds back to itself
when it opens its null chardev.
The security_dentry_open() call also now takes a creds pointer, as does the
dentry_open hook in struct security_operations.

hppfs_permission() is equivalent to the '.permission == NULL' case.

There's no reason for the _kern in hppfs_kern.c, so move it to hppfs.c.
