Hi all,

Update on this series:
  - Use a RAM address of 64bits only on 64bits targets when Xen is enable.
  - Add some comment on the memory registration done for Xen.

Xen is not limited by the QEMU's virtual address space for the allocation of
the guest RAM. So even with a QEMU 32bits, a Xen guest can have more than 4 GB
of RAM.

With this serie, we will be able to run a guest with more than 4GB. The main
point is to change ram_addr_t from ulong to uin64 when QEMU is configure with
Xen. The second point is better register the memory in QEMU.


Anthony PERARD (3):
  cpu-common: Have a ram_addr_t of uint64 with Xen.
  xen: Fix the memory registration to reflect of what is done by Xen.
  vl.c: Check the asked ram_size later.
