da4e8334b2 sparc64: Don't use devspec to determine the OBP path
Don't use devspec to determine the OBP path on SPARC hardware.  Within all
versions of Linux on SPARC, the devspec returns one of three values:
"none", "vnet-port", or "vdisk".  Unlike on PPC, none of these values
are useful in determining the OBP path.

Before this patch grub-ofpathname always returned the wrong value
for a virtual disk. For example:

% grub-ofpathname /dev/vdiskc2
vdisk/disk@2:b

After this patch it now returns the correct value:

% grub-ofpathname /dev/vdiskc2
/virtual-devices@100/channel-devices@200/disk@2:b

a2932fbe8a osdep/linux: handle autofs entries in /proc/self/mountinfo
These entries have placeholder for device name and so are useless for our
purpose. grub failed with something like

grub-install: error: failed to get canonical path of `systemd-1'.

When we see autofs entry, record it (to keep parent-child relationship) but
continue to look for real mount. If it is found, we process it as usual. If
only autofs entry exists, attempt to trigger mount by opening mount point
and retry. Mount point itself is then kept open to avoid timeout.

Recent systemd is by default using automount for /boot/efi so this should
become more popular problem on EFI systems.

5f311e86d2 fix detection of non-LUKS CRYPT
grub_util_get_dm_abstraction() does a string comparison of insufficient
length. When using a UUID such as "CRYPT-PLAIN-sda6_crypt", the function
returns GRUB_DEV_ABSTRACTION_LUKS.

This results in the error:
    ./grub-probe: error: disk `cryptouuid/sda6_crypt' not found.

This appears to be a copy/paste error introduced in:
a10e7a5a89

The bug was (apparently) latent until revealed by:

7a5b301e3a build: Use AC_HEADER_MAJOR to find device macros
Depending on the OS/libc, device macros are defined in different
headers. This change ensures we include the right one.

sys/types.h - BSD
sys/mkdev.h - Sun
sys/sysmacros.h - glibc (Linux)

glibc currently pulls sys/sysmacros.h into sys/types.h, but this may
change in a future release.

3bca85b418 devmapper: check for valid device abstraction in get_grub_dev
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.

a9399f2e1e windows: correct LBA in generated EFI HDD media paths
GRUB keeps partition offset and size in units of 512B sectors. Media paths
are defined in terms of LBA which are presumed to match HDD sector size.

This is probably cosmetic (EFI requires that partition is searched by GUID)
and still incorrect if GPT was created using different logical block size.
But current code is obviously wrong and new has better chances to be correct.

7a210304eb Fix missing byte order conversion in get_btrfs_fs_prefix function

1a33de8b56 Recognize EFI platform even in case of mismatch between Linux and EFI.
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.

049f63824c Ignore EPERM when modifying kern.geom.debugflags
Many tests fail when run as a non-root user on FreeBSD.  The failures
all amount to an inability to open files using grub_util_fd_open,
because we cannot set the kern.geom.debugflags sysctl.  This sysctl is
indeed important to allow us to do such things as installing GRUB to the
MBR, but if we need to do that and can't then we will get an error
later.  Enforcing it here is unnecessary and prevents otherwise
perfectly reasonable operations.
