    xen/pvh: Move Xen code for getting mem map via hcall out of common file · a43fb7da
    Maran Wilson authored
    We need to refactor PVH entry code so that support for other hypervisors
    like Qemu/KVM can be added more easily.
    The original design for PVH entry in Xen guests relies on being able to
    obtain the memory map from the hypervisor using a hypercall. When we
    extend the PVH entry ABI to support other hypervisors like Qemu/KVM,
    a new mechanism will be added that allows the guest to get the memory
    map without needing to use hypercalls.
    For Xen guests, the hypercall approach will still be supported. In
    preparation for adding support for other hypervisors, we can move the
    code that uses hypercalls into the Xen specific file. This will allow us
    to compile kernels in the future without CONFIG_XEN that are still capable
    of being booted as a Qemu/KVM guest via the PVH entry point.
