This was lost when code was refactored. Patch restores previous behavior.

It is still not clear whether this is the right one. Due to the way we
detect DM abstraction, partitions on DM are skipped, we fall through to
generic detection which ends up in assuming parent device is BIOS disk.

It is useful to install GRUB on VM disk from the host. But it also means
that GRUB will mistakenly allow install on real system as well.

For now let's fix regression; future behavior needs to be discussed.

Closes: 45163

Since btrfs on-disk format uses little-endian, the searched item types
(ROOT_REF, INODE_REF) need converting the byte order in order to
function properly on big-endian systems.

grub_util_{info,warn,error} already add trailing newlines, so remove
them from format strings. Also trailing full stops are already added.

Some x86 systems might be capable of running a 64-bit Linux kernel but
only use a 32-bit EFI (e.g. Intel Bay Trail systems). It's useful for
grub-install to be able to recognise such systems, to set the default
x86 platform correctly.

To allow grub-install to know the size of the firmware rather than
just the size of the kernel, there is now an extra EFI sysfs file to
describe the underlying firmware. Read that if possible, otherwise
fall back to the kernel type as before.

strlcpy is not available on Linux as part of standard libraries.
It probably is not worth extra configure checks espicially as we
need to handle missing function anyway.

	* grub-core/osdep/linux/getroot.c (grub_util_part_to_disk): Detect
	/dev/loopX as being the parent of /dev/loopXpY.

	follow the same algorithm to avoid method mismatch. Don't assume
	DMRAID- UUID to mean full disk but instead check that mapping is linear.

As suggested by Vladimir Serbienko, add additional verbose output to inform
why we selected this specific platform.

modprobe -q still prints error on non-EFI. Redirect stderr instead.

* grub-core/osdep/linux/hostdisk.c
(grub_util_find_partition_start_os): Initialise start to avoid
spurious compiler warning.

This lets us cope with block device drivers that don't implement
HDIO_GETGEO.  Fixes Ubuntu bug #1237519.

* grub-core/osdep/linux/hostdisk.c (sysfs_partition_path): New
function.
(sysfs_partition_start): Likewise.
(grub_util_find_partition_start_os): Try sysfs_partition_start
before HDIO_GETGEO.
