I am not sure how many architectures you are trying to cover, but powerpc is one I care about :-) I have dropped the access_once tree again today, sorry (its too late at night). --=20 Cheers, Stephen Rothwell sfr@canb.auug.org.au --Sig_/A=bv69.VVArYVLGKVtsDaBW Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCAAGBQJUhYr3AAoJEMDTa8Ir7ZwVaIQP/162dexk3to+Y9RDaXMOwrq0 fSzrsad3Vv/mV025ZyXpCRyD6ijYRCrRIHJN7eoql2GsknOQX5yTW6nlJWjIjcUy 6OQx1G3ajRHFBNEkHLzgbG/+A1IiFAJGl9GVHnVl4GEFF+iiv95YeRgoo4hQ3ZaI XxQNPTcuGeWGny6RJY6h1UyevmcQu3siU3vQ7tMHJ/wna+/M6n+VG+p4UiYcLkEc tm6WvEA5JefOqv++JX9Emw7a/I8EFbjUuKQIc9g+a5j4jc/IFcLZ2+xQyIFzIm/b k2l1dtH5gdoGb0RKOoN6NN1/su9osqIN0W0ENNDfqEH7pGfmv/ZKggsu1tr1TzCF ZECV+Y9YI0oC5SxRPw0HEJfmAKhpZkQ283sWVqzN1BxiY/xmE0avXNhZZPHBQRl8 Uvb8ebHtgds4J270NUD0blE12buMRSYymnN9uQB1dMpK19Bq11S9hf0OVoN4idZo szXOrQRyyrKeNhRDhNRyieAaBN+PKFl7U2EuZVHq82kFtkbnWzmJILPGbRvdLABH jbxNNuidTVR5+/O38B/8qXuGsm3y4a6nXfhIkQCvbjEanqkG8qUG8ICxBSU8Zojp T+CZUWOQ5Wxv++AJ8iHgRFVPhAVi1ENLNv28SKrFk+U031Teor/+dJJC0Sv7kc62 Ho5YS3s3YYMv0XyEkQxf =m+Ij -----END PGP SIGNATURE----- --Sig_/A=bv69.VVArYVLGKVtsDaBW--
