You can just use koji scratch builds if you want to test Fedora kernels
Either arm-koji or ppc-koji should work.  If you want actual access to a
machine, I'm sure we can find one.

The error that is hitting ARM and ppc before your patch seemed to also
be hit with sparc and was fixed by David Miller with commit 776260818
by just pointing to "../../arch/sparc/include/uapi/asm/unistd.h".  That
might be a temporary solution.
