SPARCs do not like unaligned halfword access and throw SIGBUS.
Read data "manually" instead.

Try DIOCGMEDIASIZE ioctl() if defined, to obtain
the media size on FreeBSD 5.0 and newer.
The binary search fallback doesn't work, as FreeBSD
block devices are unbuffered and refuse reads below
the block size.

This fixes some (but not all) of the compatibility bugs which prevented
e2fsprogs from being compiled on a Linux 2.0.35 system. There are still
some unprotected use of long long's, and apparently some type problems
with the uuid library, but these can be fixed up later.

Use EXT2_MAX_BLOCK_SIZE instead of a hardcoded blocksize of 32768, since
this will fail on a filesystem with a 64k blocksize. (Addresses SourceForge
bug #1424311)

We were complaining with a confusing error message if the user tried to specify
a check interval larger than a 365 days. It's probably a bad idea if the user wants to
do this, but it's not worth it to complain.

Add missing brelse() calls to avoid memory leaks in error paths. (Thanks
to Michael C. Thompson for pointing these out; they were originally
found using Coverity.)

Resize2fs will now automatically determine the RAID stride parameter that
had been used to create the filesystem, and use that for newly created
block groups. The RAID stride parameter may also be manually specified
on the command line using the new -S option to resize2fs.

The exlcusive device safety check that was added inadvertently broke
e2fsck -cc and mke2fs -cc since e2fsck and mke2fs hold the device
in exclusive access when badblocks is run. So we add a private option
to badblocks, -X, which is passed by e2fsck and mke2fs to badblocks
to indicate that it is OK to skip the EXT2_MF_BUSY checks.

Recent glibc's no longer accept LD_ASSUME_KERNEL=2.4; this must be LD_ASSUME_KERNEL=2.4.1. Also, only set LD_ASSUME_KERNEL if we
are not using a 2.4 kernel (and are presumably using something newer)

When allocating space for the RAID filesystems with the stride parameter,
place each portion of the group's inode table right up after the superblock
(if present) in order to minimize fragmentation of the freespace.

This feature is initially intended for testing purposes; it allows an
ext2/ext3 developer to create very large filesystems using sparse files
where most of the block groups are not initialized and so do not require
much disk space. Eventually it could be used as a way of speeding up
mke2fs and e2fsck for large filesystem, but that would be best done by
adding an RO_COMPAT extension to the filesystem to allow the inode table
to be lazily initialized on a per-block basis, instead of being entirely initialized
or entirely unused on a per-blockgroup basis.

Currently filefrag uses signed int for block numbers, thus it reporting
corrupted block number for a file on a more than 8TB ext3. The following
trivial patch replace the signed int type block number with "unsigned

This caused FTBFS bugs on AMD64 platforms, since it uses a different
64-bit type when compared with IA64, so we need to make our
autoconfiguration system more intelligent.

If the filesystem is opened in exclusive mode, then device will be
busy by definition, so don't return -EBUSY. This caused mke2fs -j to
