Hi Lei,
I'm copying Andy Doan directly on this, since he's had more experience of

Hi all,
this patch series implements Xen support for ARMv7 with virtualization
extensions. It allows a Linux guest to boot as dom0 and
as domU on Xen on ARM. PV console, disk and network frontends and
backends are all working correctly.
It has been tested on a Versatile Express Cortex A15

Check for a node in the device tree compatible with xen,xen, if it is
present set xen_domain_type to XEN_HVM_DOMAIN and continue
initialization.
Map the real shared info page using XENMEM_add_to_physmap with
XENMAPSPACE_shared_info.
Changes in v4:
- simpler parsing of Xen version in the
sync_bitops functions are equivalent to the SMP implementation of the
original functions, independently from CONFIG_SMP being defined.
We need them because _set_bit etc are not SMP safe if !CONFIG_SMP. But
under Xen you might be communicating with a completely external entity
who might be on
Use r12 to pass the hypercall number to the hypervisor.
We need a register to pass the hypercall number because we might not
know it at compile time and HVC only takes an immediate argument.
Among the available registers r12 seems to be the best choice because it
is defined as intra-procedure
ARM Xen guests always use paging in hardware, like PV on HVM guests in
the X86 world.

All the original Xen headers have xen_ulong_t as unsigned long type, however
when they have been imported in Linux, xen_ulong_t has been replaced with
unsigned long. That might work for x86 and ia64 but it does not for arm.
