Trond Myklebust df486a2590 NFS: Fix the selection of security flavours in Kconfig
Randy Dunlap reports:

ERROR: "svc_gss_principal" [fs/nfs/nfs.ko] undefined!


because in fs/nfs/Kconfig, NFS_V4 selects RPCSEC_GSS_KRB5
and/or in fs/nfsd/Kconfig, NFSD_V4 selects RPCSEC_GSS_KRB5.

RPCSEC_GSS_KRB5 does 5 selects, but none of these is enforced/followed
by the fs/nfs[d]/Kconfig configs:

	select SUNRPC_GSS
	select CRYPTO
	select CRYPTO_MD5
	select CRYPTO_DES
	select CRYPTO_CBC

This option allows the NFS client and server to support
an RDMA-enabled transport.
To compile RPC client RDMA transport support as a module,
choose M here: the module will be called xprtrdma.
If unsure, say N.

Choose Y here to enable Secure RPC using the Kerberos version 5
GSS-API mechanism (RFC 1964).
Secure RPC calls with Kerberos require an auxiliary user-space
daemon which may be found in the Linux nfs-utils package
available from http://linux-nfs.org/. In addition, user-space
Kerberos support should be installed.
If unsure, say Y.

Choose Y here to enable Secure RPC using the SPKM3 public key
GSS-API mechanism (RFC 2025).
Secure RPC calls with SPKM3 require an auxiliary userspace
daemon which may be found in the Linux nfs-utils package
available from http://linux-nfs.org/.
If unsure, say N.
