We always reserve these ranges since we never allow any stuff to
poke them.
But in theory some untrusted VM can maliciously access them. So we
need to intercept this approach. But we just don't want to leak
anything or introduce any side affect since other OSs may touch them
by careless behavior,
In some cases like igd_opregion_pgbase, guest will use mem_hole_alloc
to allocate some memory to use in runtime cycle, so we alsoe need to
make sure all reserved device memory don't overlap such a region.

We need to check to reserve all reserved device memory maps in e820
to avoid any potential guest memory conflict.
Currently, if we can't insert RDM entries directly, we may need to handle
several ranges as follows:
a. Fixed Ranges -- BUG()
lowmem_reserved_base-0xA: reserved by BIOS
We will create RMRR mapping as follows:
If gfn space unoccupied, we just set that. If

intel_iommu_map_page() does nothing if VT-d shares EPT page table.
So rmrr_identity_mapping() never create RMRR mapping but in some
cases like some GFX drivers it still need to access RMRR.
Here we will create those RMRR mappings even in shared EPT case.

guest configuration.
This will be used in later patch.

Make XENMEM_increase_reservation and XENMEM_populate_physmap
vNUMA-aware.
That is, if guest requests Xen to allocate memory for specific vnode,
Xen can translate vnode to pnode using vNUMA information of that guest.
XENMEMF_vnode is introduced for the guest to mark the node number is in
fact
One vmemrange is generated for each vnode. And for those guests who care
about machine E820 map, vmemranges are further split to accommodate
memory holes.

Currently we haven't exported vmemrange interface to libxl user.
Vmemranges are generated during domain build.

Hi all
This is version 2 of this series.
This patch series implements virtual NUMA support for both PV and HVM guest.
That is, admin can configure via libxl what virtual NUMA topology the guest
sees.
This is the stage 1 (basic vNUMA support) and part of stage 2 (vNUMA-ware

Libxc has more involvement in building vmemranges in HVM case. The
building of vmemranges is placed after xc_hvm_build returns, because it
relies on memory hole information provided by xc_hvm_build.

Disallow memory relocation when vNUMA is enabled, because relocated
memory ends up off node. Further more, even if we dynamically expand
node coverage in hvmloader, low memory and high memory may reside
in different physical nodes, blindly relocating low memory to high
memory gives us a

This is done with three major changes:
1. Rework internal representation of setting.
2. Extend grammar of parser.
3. Introduce new APIs.
New APIs introduced:
1. xlu_cfg_value_type
2. xlu_cfg_value_get_string
3. xlu_cfg_value_get_list
4. xlu_cfg_get_listitem2
Previous APIs work as before.
