* kern/disk.c (grub_disk_read): When there is a read error, always
	try to read only the necessary data.

	* conf/i386-pc.rmk (grub_probe_SOURCES): Add disk/lvm.c and
	disk/raid.c.
	* include/grub/disk.h [GRUB_UTIL] (grub_raid_init): New
	prototype.
	[GRUB_UTIL] (grub_raid_fini): Likewise.
	[GRUB_UTIL] (grub_lvm_init): Likewise.
	[GRUB_UTIL] (grub_lvm_fini): Likewise.
	* util/i386/pc/grub-probe.c (probe): Check whether DEVICE_NAME is
	RAID device and copy DEVICE_NAME to DRIVE_NAME in that case.
	(main): Call grub_raid_init(), grub_lvm_init(), grub_lvm_fini()
	and grub_raid_fini().
