From: Vlad-Andrei BĂDOIU (78692) <vlad_andrei.badoiu@xxxxxxxxxxxxxxx> This patch adds the eh_frame and eh_frame hdr sections to the linker script for both XEN and KVM. A new linker script has been created plat/common/x86/link64.lds in order to avoid code duplication. This patch adds the frames to the linker scripts.
