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 v3:
- use the xen,xen notation rather than arm,xen;
Changes in v2:
- return -ENOSYS rather than -1.

All the original Xen headers have xen_pfn_t as mfn and pfn type, however
when they have been imported in Linux, xen_pfn_t has been replaced with
unsigned long. That might work for x86 and ia64 but it does not for arm.
Bring back xen_pfn_t and let each architecture define xen_pfn_t as they
see fit.
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.
Changes in v3:
- improve comments.

sync_bitops functions are equivalent to the SMP implementation of the

We need them because _set_bit etc are not SMP safe if !CONFIG_SMP. But

This is a simple, hacky implementation of xen_remap_domain_mfn_range,
using XENMAPSPACE_gmfn_foreign.
It should use same interface as hybrid x86.
Changes in v2:
- retain binary compatibility in xen_add_to_physmap: use a union.

Initialize the grant table mapping at the address specified at index 0
in the DT under the /xen node.
After the grant table is initialized, call xenbus_probe (if not dom0).
Changes in v2:
- introduce GRANT_TABLE_PHYSADDR;
- remove unneeded initialization of boot_max_nr_grant_frames.
Reset the IRQ_NOAUTOEN and IRQ_NOREQUEST flags that are enabled by
default on ARM. If IRQ_NOAUTOEN is set, __setup_irq doesn't call
irq_startup, that is responsible for calling irq_unmask at startup time.
As a result event channels remain masked.

Cross-compiling is tricky because perf requires a lot of libraries.
I do it natively, using Ubuntu developer image. Also note that
