Hi all,

This is an update to the patch that allows a user to change the
translation granule in arm64. Special thanks to Drew and Alex for
having a look at the code and their suggestions.

v1: https://lore.kernel.org/kvm/006a19c0-cdf7-e76c-8335-03034bea9c7e@arm.com/T

Changes in v2:
 - Change the configure option from page-shift to page-size
 - Check and warn if the configured granule is not supported

Thanks,

Nikos
