Subject: Re: [PATCH v6 2/7] arm64: Introduce VA_BITS and translation level
 options

I agree that these patches would be very useful.  I just rebased my fix
for a VTTBR_BADDR_MASK bug on one of these patches that could be pulled
out independently.  See
https://lists.cs.columbia.edu/pipermail/kvmarm/2014-July/010480.html

The original author Jungseok Lee is no longer available to work on
future versions of these patches.  I was thinking that if they didn't
get picked up as they are that with the original author's blessing I
would pick them up and keep them forward ported/resubmitted.  I have an
SOC to test them on.
