Well, I can't say yes or no to "simpler" or "easier to follow", but
splitting is the goal, in the hope that these may end up as a side
effects. There's always the risk that scattering things around may
also make things less obvious. My main motivation, however, is the
observation that this huge source file alone consumes a fair part
of (non-parallelizable) build time. To the degree that with older
gcc building this one file takes ten (or so) times as long as the
entire rest of the hypervisor.
