Add support for reading/writing FFS in non-native byte order, conditioned
...
to "options FFS_EI". The superblock and inodes (without blk addr) are
byteswapped at disk read/write time, other metadatas are byteswapped
when used (as they are acceeded directly in the buffer cache).
This required the addition of a "um_flags" field to struct ufsmount.
ffs_bswap.c contains superblock and inode byteswap routines also used
by userland utilities.

In ext2fs, an inode is deleted either when mode == 0 or dtime != 0. If
dtime != 0, reset others fields before using the inode, or we could end

Don't cast 64bit (off_t) file sizes to vm_offset_t (32bit on many
...
architectures), truncate them intelligently instead.
The truncation is done centralized in vnode_pager.c.
This prevents from wrap-over effects when parts of large (>2^32 byte) files
are mmapped.
Don't allow to mmap above the numerical range of vm_offset_t.
This is considered a temporary solution until the vm system handles the
object sizes/offsets more cleanly.
