grub2/include/grub/emu/hostdisk.h
Colin Watson e3c78337c3 * include/grub/partition.h (grub_partition_map): Change prototype of
embed to take a maximum value for nsectors.
	* include/grub/emu/hostdisk.h (grub_util_ldm_embed): Likewise.
	* include/grub/fs.h (grub_fs): Likewise.
	* grub-core/partmap/msdos.c (embed_signatures): New array.
	(pc_partition_map_embed): Check for and avoid sectors matching any
	of the signatures in embed_signatures, up to max_nsectors.
	* grub-core/partmap/gpt.c (gpt_partition_map_embed): Restrict
	returned sector map to max_nsectors.
	* grub-core/disk/ldm.c (grub_util_ldm_embed): Likewise.
	* grub-core/fs/btrfs.c (grub_btrfs_embed): Likewise.
	* grub-core/fs/zfs/zfs.c (grub_zfs_embed): Likewise.
	* util/grub-setup.c (setup): Allow for the embedding area being
	split into multiple blocklists.  Tell dest_partmap->embed the
	maximum number of sectors we care about.
