[Xen-changelog] [qemu-xen-unstable] remove check on ram_size

[Ian Jackson <Ian.Jackson@xxxxxxxxxxxxx>]

commit f5b4a6be712e2a3a0bdb444e5e87de3d17019965
Author: Ian Jackson <ian.jackson@xxxxxxxxxxxxx>

    remove check on ram_size
    
    the initial check on the ram_size in qemu is completely unnecessary and
    it is even broken on systems where dom0 is 32 bits while xen is 64 bits.
    This patch solves the problem removing the check.
