Modified to provide building of the xenalyze binary for both ARM and
x86 platforms. The xenalyze binary is now built as part of the BIN

Changed since v1:
* Changed xenalyze

casting.
get_s_time() was also modified to now use the updated get_cycles() to
retrieve the tick count instead of directly reading it.

Check added to determine read/write or read only page type when
requesting DOMID_XEN. This is done by checking the u.inuse.type_info
parameter of the requested page. The page rw/ro paddr_t type is then
set accordingly.

, XENMAPSPACE_gmfn_foreign page mapping and address translation
for DOMID_XEN is corrected in mm.c and p2m.c, and timestamping for the

Finally the xenaylze makefile is configured to build the tool for ARM.

xenalyze: Support for ARM platform
Moved get_pg_owner() and put_pg_owner() from the arch specific mm.c
source files into the common page_alloc.c source. This was done as
theses functions are now needed by both architectures to support
xentrace on the ARM platform. Forward declarations were added to mm.h.

Modified xenmem_add_to_physmap_one() to provide support for xentrace
on the ARM platform. Checks for DOMID_XEN added via new function,
get_pg_owner, ported and commonized from x86 code base. This provides
correct calls to rcu_lock_domain() when DOMID_XEN is requested.

This patch sets adds support for xentrace and xenalyze to the ARM platform.
The Xen heap memory mapping, timestamping, and P2M translation needed by
xentrace is corrected for operation on the ARM platform using the x86
platform as reference. Trace buffer initialization is added to
24 matches
