The config I attached in my previous email differs from the
malta_defconfig. The former is pretty minimal, and contains only the
stuff which is just necessary and sufficient to boot up the Timesys
userspace. I also use this config to boot a Debian-based system.

As for the allnoconfig, it usually builds for me, and I use allnoconfig
as one of the sanity tests in the context of my own development process.

The allmodconfig has been broken for some time, and you need to manually
disable several options (the diff between the allmodconfig and the
buildable configuration is attached to this email).

To get a buildable config out of allyesconfig, one needs to manually
disable the CONFIG_VORTEX option.

I have no 64-bit MIPS hardware, so I can't help with these platforms,
unfortunately.

I just checked malta_defconfig. Current Linus' tree built without
errors, and I also was able to boot a Qemu-based system. So, I believe
that malta_defconfig can be used for the linux-next test builds instead
of (or along with) the config that I sent earlier.
