hwclock: [m68k] unbreak FTBFS with recent (>= 2.4.18?) kernels
The old KDGHWCLK ioctl was removed from the Linux kernel quite some
time ago. The kd.c source file of hwclock contains fallback code to
handle this, but the fallback code never could have compiled or was
not fixed along other code changes. The Linux kernel nowadays igno-
res the ioctl entirely so removing it unless provided by the kernel
headers, to keep it working on very old kernels, seems the sensible
thing to do, as the comments say m68k only and deprecated (which is
correct AFAICT).
According to pickaxe on gitweb, it was removed in 2002:

fdisk: fix -b <sectorsize>
The old fdisk (<2.17) does not differentiate between logical and
physical sector size, it uses the <sectorsize> for everything.
Now, we have logical and physical sectors size, but the -b option
changes the logical size only. The second bug is that "fdisk -b <sz>"
does not read topology information (it means that all I/O limits and
physical sector size are 512 (default).
The backwardly compatible bug fix is to override both sizes, logical
and physical if "-b" is used.
In future we can add a special option for physical size only.

libblkid: fix infinite loop when probe chain bails out early
The superblocks probe bails out early with no results in some cases. If
this happens, blkid_do_probe needs to go to the next chain, rather than
entering an infinite loop calling superblocks_probe over and over again.

mount: properly ignore comments in /etc/filesystems
The POSIX spec for sscanf() says that whitespace may be matched against 0
bytes which means doing sscanf(" %s") against "#foo" will result in a
match. You can see this behavior by using the verbose options on a garbage
file:
...
mount: you didn't specify a filesystem type for /dev/null
I will try all types mentioned in /etc/filesystems or /proc/filesystems
Trying #
mount: mount(2) syscall: source: "/dev/null", target: "/", filesystemtype: "#", mountflags: -1058209792, data: (null)

swapon: remove " (deleted)" from filenames from /proc/swaps
The filenames in /proc/swaps are generated by seq_path() and this
function uses __d_path() from fs/dcache.c. The filename could
generated with " (deleted)" suffix. We need real filenames without
the suffix.

libblkid: support alignment_offset=-1
Unfortunately, Linux kernel uses "signed int" for alignment_offset and
the offset could be -1 for devices with undefined alignment (if no
compatible sizes and alignments exist for stacked devices).
There is no way how libblkid caller can respond to the value -1, so we
are going to hide this corner case...
This patch also cleanups usage of empty topology values (e.g.
MINIMUM_IO_SIZE=0 value should not be returned by NAME=value API. The
binary blkid_topology_get_* is not affected by this change.)
Summary of changes from v2.5.42 to v2.5.43
[PATCH] removes posix option of fat (3/5)
This removes the posix option of vfat. The current posix options works
only as an alias of name_check=s.

Fixes commit c9239f23acdc8b50f8bcbfadf967c6a490fd4693. The author

constraints. The eax register (with the cpuid opcode) is now in
operand 1, not zero anymore.

libblkid: fix ZSF detection
Fix the ZFS device detection by looking at multiple uberblocks to see
if any are present, rather than looking for the ZFS boot block which
is not always present.
There may be up to 128 uberblocks, but the first 4 are not written to
disk on a newly-formatted filesystem so check several of them at
different offsets within the uberblock array.

fdisk: use 1MiB offset and grain always when possible
It would be nice to minimize dependence between the disk layout and
disk topology. We have to follow disk topology for alignment_offset
and huge (> 1MiB) I/O sizes only. For all others disks we can use 1MiB
grain and 1MiB offset.
