    ve/mm/filemap.c: include virtinfo.h for !CONFIG_BC_IO_ACCOUNTING case
    
    This was found while tring to compile the kernel with a stock
    config (i.e. no CONFIG_BEANCOUNTERS, CONFIG_VE etc.) and
    boot it on IBM Power8.
    
    =============================================================
    
    In case CONFIG_BC_IO_ACCOUNTING is not set, linux/virtinfo.h
    is not getting included into mm/filemap.c via bc/io_acct.h,
    and we have this:
    
    	mm/filemap.c: In function ‘do_generic_file_read’:
    	mm/filemap.c:1573:3: error: implicit declaration of function
    	‘virtinfo_notifier_call’ [-Werror=implicit-function-declaration]
    	   virtinfo_notifier_call(VITYPE_IO, VIRTINFO_IO_PREPARE, NULL);
