Ouch, after 'git pull' the latest Xen staging branch and see the conflict. I will send new one patch set. Please ignore this one. Thanks, Leo
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 2TB and hence causes Xen panic: (XEN) MODULE[0]: 00000807f6df0000 - 00000807f6f3e000 Xen (XEN) MODULE[1]: 00000807f8054000 - 00000807f8056000 Device Tree (XEN) MODULE[2]: 00000000fa834000 - 00000000fc5de1d5 Ramdisk (XEN) MODULE[3]: 00000000fc5df000 - 00000000ffb3f810 Kernel To fix this issue, this series is to enlarge identity map space to 127 TiB and tested on Telechips Dolphin5 platform. 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.
