While preparing another round of it, I thought there is enough 'meat' already for a separate series. Basically, there are a few places in libxc where we issue do_domctl()-s directly, instead of using the proper xc_xxx() wrapper. This make the code bigger, redundant, more difficult to understand (e.g., "why xc_xxx() is called here and is not called there?"), less consistent and less grep-able. The first 4 patches of this series address this. The last one introduce a little tool I'm using for debugging. It allows one to see the M2P of the host, the P2M of a domain, some info about the PTEs, and perform basic searches and comparisons on them. I'm finding it very useful and, although I do not claim for my situation to be that common, I figured it could be nice to have it in the tree, so that is patch 6. Patch 5 is the small rework/additions necessary to make 6 possible. Let me know what you think.
