PMD_ORDER is not necessarily constant on PowerPC (since it depends on PTE_INDEX_SIZE). I have reverted that commit (and the following one) for today. --=20 Cheers, Stephen Rothwell --Sig_/1boJlDeg2tOlPJ9PAbAo0aX Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEENIC96giZ81tWdLgKAVBC80lX0GwFAmYTKQ4ACgkQAVBC80lX 0GzgsAf/bwPry6OrXEcvi7DTSMPh/cRl/1HfvbPykZM4r6quhE3L4rEXYmjR38zy kcaENe1h9GmnpyoRJ1sI/smdSDT7Ak7wSQaoMTafq3STjr5C+yrN/cAdne1V+8lQ jwToZ/H/mSFv9jkqNQnd8ga5DLlMySewzqEMdIXh4G5F/mC8GRiDlgAtssHNI1rQ EMYyPCi1d0GamwmoNmrGDtDKytyzC14KW+yY/ChmwGfioTkt1dJfNx8J0KqldN7k hs63Kn1ubQ4P1pJxVx7zmBEM8jcT22X6le7ssBkepSaJ7IbzVWSw+rcDR40FL8jD dHLppQy/fKC89FNkoAWUypSYxWMEeg== =UaaD -----END PGP SIGNATURE----- --Sig_/1boJlDeg2tOlPJ9PAbAo0aX--
