Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 64603 Lines: 2247 - Remove some unneeded configs and add some new ones. - Merge common config items to common file instead of duplicating them. - Pull in standard Kconfig.preempt. - Remove some unneeded Kconfigs for subsystems not (yet) available on CRIS (md, scsi, ieee1394, i2o, isdn, telephony, media, pcmcia, pci) - Rename CRISv32 config items which had different types from CRISv10.
