[libvirt] PATCH: Fix numa build failure on 32-bit f9
The automated build on Fedora 9, i386 is currently failing with cc1: warnings being treated as errors nodeinfo.c: In function 'virCapsInitNUMA': nodeinfo.c:212: error: passing argument 2 of 'numa_node_to_cpus' from incompatible pointer type make[3]: *** [libvirt_driver_la-nodeinfo.lo] Error 1 make[3]: *** Waiting for unfinished jobs....

The following patch addresses it:
ACK. That looks right, since it has to match arg2 of this: static inline int numa_node_to_cpus_compat(int node, unsigned long *buffer, int buffer_len) At first glance, I had doubts about using the sometimes-narrower type, but all uses are scaled by "sizeof *mask", so if it weren't for that prototype, any unsigned type would do.

Yes, I double checked the allocation calculations again and all look to be correct, so I've committed this.
