Hi,

Rebased and addressed Richard's comments about proper masking virtualized accesses.

Thanks

[v11]:
As suggested on the mailing list by Daniel, I'm resubmitting this series and keeping the original versioning number.
So that makes this one v11 and previous - v10.
Also I applied previously issues reviewed-by tags on some of the patches that were present in v9 series, but only for the code, that didn't change much.
For the others I'd really like to have them reviewed as there were a lot of comments on v9 series.
Also rebased on the current upstream.

Thanks

[v10]:
I've rebased this patch series and addressed Richard's and Daniel's comments.
Thanks

[v0]:
As Pointer Masking is finally ratified, these patches intend to update the existing code to the final version.
These patches have been submitted previously and I tried to address all the suggestions, but I'd suggest to review them from the clean slate and then finally push them to the repo.
Thanks.
