Thank you for reporting! I see that these headers for powerpc are
generating duplicate entries. This is due to me mistakenly setting the
abis for the syscall headers for powerpc to be spu and nospu, causing
conflicts. It looks like for the uapi, only nospu needs to be exposed. I
will send a patch to fix that.
