Default Warnings building centosplis kernel-xen from .SRPM

A few weeks back I needed to rebuild the centosplus kernel-xen on
x86_64, I don't recall getting anything other than the "usual"
sprinkling of compiler warnings.


Now I've needed to rebuild the centosplus kernel-xen, this time on i686,
I do get a built and working kernel+modules, but I get a particularly
"hairy" set of warnings as follows, anyone else rebuilt this from the
.SRPMs and had similar, do those warnings look bad to anyone else? Or is
it normal with 32bit xen?

Unfortunately, it's notmal to see a variying number of "WARNING: vmlinux - Section mismatch: " messages with builds of *any* (not just the xen) kernel and is the result of upstream.

Do not worry about them.
