	From Sergey Matveychuk <sem@ciam.ru>:
	* lib/device.c (get_drive_geometry): Do not open the same device
	more than once unnecessarily.
	(get_drive_geometry) [__FreeBSD_version >= 500040]: Use new
	ioctl methods.
	(get_floppy_disk_name) [__FreeBSD__ >= 4]: Use /dev/fd%d rather
	than /dev/rfd%d.
	(get_ide_disk_name) [__FreeBSD__ >= 4]: Use /dev/ad%d rather
	than /dev/rad%d.
	(get_scsi_disk_name) [__FreeBSD__ >= 4]: Use /dev/da%d rather
	than /dev/rda%d.
	* grub/asmstub.c (get_diskinfo): Check if ERRNO is EPERM as
