For the benefit of discussion, we refer to max_memkb inside hypervisor
as hv_max_memkb (name subject to improvement). That's the maximum number
of memory a domain can use.
Libxl doesn't know hv_max_memkb for a domain needs prior to QEMU start-up
because of optional

move toolstack code into libxl_toolstack.c
It's not clear to me what toolstack code is here, the whole of libxl
and xl is toolstack code.
Is the code being moved stuff to do with adding toolstack state to the

version 3
Unmediated PCI register access in qemu
UPDATES IN VERSION 3
Public release.
CVE assigned.
ISSUE DESCRIPTION
Using gdbsx on Broadwell systems suffers a SMAP violation because
dbg_rw_guest_mem() uses memcpy() with a userspace pointer.
The functions dbg_rw_mem() and dbg_rw_guest_mem() have been updated to pass
'void * __user' pointers which indicates their nature clearly.

Apart from dropping some static and adding some prototypes to the
header this is purely motion, correct? (I assume this about the last one
too).
