xen-hvm: reorganize xen-hvm and move common function to xen-hvm-common 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.
