The latest Xen fails to boot on ADLink AVA platform. Alexey Klimov root caused the issue is related with the commit 1c78d76b67 ("xen/arm64: mm: Introduce helpers to prepare/enable/disable"). This is because on ADLink AVA platform, it loads Xen hypervisor to the address above 8TB and hence causes Xen panic (see patch 02 for details). To fix this issue, this series is to enlarge identity map space to 127 TiB and tested on AVA platform. Changes from v2: - Kept macro naming IDENTITY_MAPPING_AREA_NR_L0 and removed introduced macros (Julien Grall). - Minor improvement for coding style (Julien Grall). - Added platform's detail in the patch 02 commit log (Julien Grall). Changes from v1: - Rebased on staging branch (Bertrand); - Added Alexey Klimov tested tag for patch 01 (Alexey). - Corrected the printing log with dynamically calculation ID map size.
