Hi,
References: <20131125085630.417850406@dhcp-16-126.nay.redhat.com>
Content-Disposition: inline; filename=11-reserve-setup-data-late.patch
Kdump kernel using memmap=exactmap, move e820_reserve_setup_data after
parsing early params so they can be set reserved finally. Or kdump kernel
will warn about ioremap a normal ram range.
