[PATCH v4 00/19] xen: add pvh guest support

[Juergen Gross]

This patch series adds support for booting Linux as PVH guest.

Similar to i386/xen and x86_64/xen platforms the new i386/xenpvh
platform grub is booted as a standalone image directly by Xen.

For booting Linux kernel it is using the standard linux kernel
loader. The only modification of the linux loader is to pass the
ACPI RSDP address via boot parameters to the kernel, as that table
might not be located at the usual physical address just below 1MB.

The related Linux kernel patches have been accepted in the merge
window for post 4.19 (4.20 or 5.0, whatever it will be called).

Changes in V4:
- added new patch 12
- write modified memory map back to Xen

Changes in V3:
- addressed lots of comments, most by Daniel and some by Roger,
  details are mentioned in the individual patches

Changes in V2:
- extend linux boot protocol version 2.14 to report back the protocol
  version supported by grub2 (needed as there are grub2 downstream
  variants in some distros which clobber data after the setup_header)
- split former patch 4 into 10 patches
- fix memmap handling for >4GB of memory
- added new patch from Hans (thanks for that one)
- addressed most of Daniel's comments (see individual patches)
