Hi Julien,
Hi Henry,
I've done some test about the patch series in
https://xenbits.xen.org/gitweb/?p=people/julieng/xen-
unstable.git;a=shortlog;h=refs/heads/pt/rfc-v2
Thanks you for the testing. Some questions below.
I am a bit confused with the output with and without my patches. Both of
them are showing a data abort in clear_page().
Above, you suggested that there is a big gap between the two memory
banks. Are the banks still point to actual RAM?
Another sorry for the very late reply, we had a 5 day public holiday in
China and it also took me some time to figure out how to configure the
FVP (it turned out I have to set -C bp.secure_memory=false to access
some parts of memory higher than 4G).
No worries. I never tried to tweak the memory layout on the FVP before.
It is good to know it can be done to properly test memory issue :).

This is happening without my patch series applied, right? If so, what
happen if you apply it?
