I did a compile testing of all mips defconfigs in 2.6.25-rc2. The results were: Systems without a defconfig: CONFIG_BCM47XX CONFIG_SGI_IP28 CONFIG_SIBYTE_CRHINE CONFIG_SIBYTE_CARMEL CONFIG_SIBYTE_CRHONE CONFIG_SIBYTE_RHONE CONFIG_SIBYTE_LITTLESUR CONFIG_SIBYTE_SENTOSA Can people using these systems provide defconfig's for them? A defconfig is nothing special, it's enough to simply put the .config used for one machine into arch/mips/configs/ .

I don't know which special gcc versions have these options added, but when they are used by the kernel they should also go into upstream gcc.
