Well, yes, there should be a bugzilla.  What exactly the bug is depends 
on the kernel RPM maintainer's intended wishes for the kernel-devel 
package.  If he wanted the ppc kernel-devel to be self sufficient, then 
he should have included all asm-ppc64 header files that were included by 
asm-ppc header files and not having them in the kernel-devel.ppc package 
is the bug.  However, doing things this way probably precludes 
installing both the kernel-devel.ppc and kernel-devel.ppc64 packages at 
the same time.

If, on the other hand, he wanted the ppc devel package to be pure and 
not include ppc64 header files, then he needs to make sure that A) both 
the kernel-devel.ppc and kernel-devel.ppc64 rpms can be installed at the 
same time and B) that the kernel-devel.ppc RPM has a Requires: 
kernel-devel.ppc64 item in there to avoid this dangling header include 
problem that currently exists.
