Turns out the issue regarding ptr_arith and sign_exension weren't false positives. When shifting an 'unsigned char' as a target, it gets promoted to an 'int'; however, that 'int' cannot be shifted 32 bits which was how the algorithm was written. For the ptr_arith rather than index into the cpumap, change the to address as necessary and assign directly.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
