From 63b624140a5b1123acb18ad97e7bb12190667bac Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Wed, 1 Jun 2016 15:51:06 +0800 Subject: [PATCH] xen/arm64: config: Correctly define VMAP_VIRT_END The vmap initialization code (vm_init_type) will round down the end of the region to a page-aligned address. On ARM64, the default vmap region is located between 1G and 2G. Based on the initialization code, the end address is excluded of the region. Therefore the current definition of VMAP_VIRT_END will lead the vmap code to not use the last 4K of the region. Fix it by defining VMAP_VIRT_END as "VMAP_VIRT_START + GB(1)".
