Hi Ingo,

But that's axiomatic, isnt it? linux-next build-tests PowerPC as the

ever cause a build failure on PowerPC, right?

Not really.  I build a powerpc ppc64_defconfig and an x86_64 allmodconfig
between merging most trees.  At the end of the day, I do the following
builds before releasing linux-next:

powerpc allnoconfig
powerpc64 allnoconfig
powerpc ppc44x_defconfig
powerpc allyesconfig
i386 defconfig
sparc64 defconfig
sparc defconfig

Which clearly doesn't cover all possible configs, but is a start and
catches a lot (the powerpc allyesconfig is only 64 bit).

Then after release, linux-next gets built for a lot of architectures and
configs (see http://kisskb.ellerman.id.au/kisskb/branch/9/).  A couple of
people also do randconfig builds which find all sorts of things.
