[Xen-devel] [PATCH v7 01/14] x86: move xen ELF end of image to 16 MiB

2016-09-23 Thread Daniel Kiper
It seems that from xen ELF image POV _end symbol properly determine image end. However, taking into account that initial Xen image mapping covers 16 MiB it looks that it is not sufficient. Currently bootloader potentially may load xen ELF image at 1 MiB and let's say put Linux kernel or initrd at 8
