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

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.
