Roel Kluin 880fe76ee6 hppfs: hppfs_read_file() may return -ERROR
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.

David Howells d76b0d9b2d CRED: Use creds in file structs
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.

David Howells 745ca2475a CRED: Pass credentials through dentry_open()
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.

Jeff Dike 46d7b522eb uml: move hppfs_kern.c to hppfs.c
There's no reason for the _kern in hppfs_kern.c, so move it to hppfs.c.
