Indeed, you don't really need LPAE. What you may need though is
generic timers support for A15, it would allow less Hypervisor traps.
For up-to-date architecture patches (well, development tree, not
guaranteed to be stable), I would recommend this (they get into
mainline at some point):

http://git.kernel.org/?p=linux/kernel/git/cmarinas/linux-arm-arch.git;a=summary

Either use master or just cherry-pick the branches that you are interested in.
