This patch does following:
1. creates arch_handle_ioreq() and arch_xen_set_memory(). This is done in
preparation for moving most of xen-hvm code to an arch-neutral location,
move the x86-specific portion of xen_set_memory to arch_xen_set_memory.
Also, move handle_vmport_ioreq to arch_handle_ioreq.
2. Pure code movement: move common functions to hw/xen/xen-hvm-common.c
Extract common functionalities from hw/i386/xen/xen-hvm.c and move them to
hw/xen/xen-hvm-common.c. These common functions are useful for creating
an IOREQ server.
xen_hvm_init_pc() contains the architecture independent code for creating
and mapping a IOREQ server, connecting memory and IO listeners, initializing
a xen bus and registering backends. Moved this common xen code to a new
function xen_register_ioreq() which can be used by both x86 and ARM machines.
Following functions are moved to hw/xen/xen-hvm-common.c:
xen_vcpu_eport(), xen_vcpu_ioreq(), xen_ram_alloc(), xen_set_memory(),
xen_region_add(), xen_region_del(), xen_io_add(), xen_io_del(),
xen_device_realize(), xen_device_unrealize(),
cpu_get_ioreq_from_shared_memory(), cpu_get_ioreq(), do_inp(),
do_outp(), rw_phys_req_item(), read_phys_req_item(),
write_phys_req_item(), cpu_ioreq_pio(), cpu_ioreq_move(),
cpu_ioreq_config(), handle_ioreq(), handle_buffered_iopage(),
handle_buffered_io(), cpu_handle_ioreq(), xen_main_loop_prepare(),
xen_hvm_change_state_handler(), xen_exit_notifier(),
xen_map_ioreq_server(), destroy_hvm_domain() and
xen_shutdown_fatal_error()
3. Removed static type from below functions:
1. xen_region_add()
2. xen_region_del()
3. xen_io_add()
4. xen_io_del()
5. xen_device_realize()
6. xen_device_unrealize()
7. xen_hvm_change_state_handler()
8. cpu_ioreq_pio()
9. xen_exit_notifier()
4. Replace TARGET_PAGE_SIZE with XC_PAGE_SIZE to match the page side with Xen.
