Subject: kvm broken with new vmap

Hello Nick,

KVM is currently broken upstream, starting with commit
db64fe02258f1507e13fe5212a989922323685ce (rewrite vmap layer)

The symptoms are some vmallocs from kvm fail.
cat /proc/meminfo shows this at the time of the fail:

VmallocTotal:     122880 kB
VmallocUsed:       15184 kB
VmallocChunk:      83764 kB

so there's plenty of space.

The allocation that fails seem to be 512 bytes long. I'm not
sure it always fails in there, but it seems so.
