-Subject: [PATCH 1/2] xen/page_alloc: Cover memory unreserved after boot in
- first_valid_mfn
-
-On Arm, some regions (e.g Initramfs, Dom0 Kernel...) are marked as
-reserved until the hardware domain is built and they are copied into its
-memory. Therefore, they will not be added in the boot allocator via
-init_boot_pages.
-
-Instead, init_xenheap_pages will be called once the region are not used
-anymore.
-
-Update first_valid_mfn in both init_heap_pages and init_boot_pages
-(already exist) to cover all the cases.
