mrg b3d5e1889f pull across patches from warner losh <imp@freebsd.org> (freebsd ufs_vnops.c
versions 1.109&1.110), adjusted for our ext2fs support, and also commited
there also.  this avoids overflowing the link count.

bouyer dc306354b0 Move the bswap functions from libutil to libc (this bups the
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.

* in the write vnode operator, update the appropriate checks for IO_SYNC being
  set in the ioflag to reflect that IO_DSYNC is now inclusive-or'ed into
  IO_SYNC, and require all IO_SYNC bits to be set for operations defined by
  synchronized I/O file integrity completion but not by synchronized I/O data
  integrity completion.

cgd 651b44e211 Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

bouyer 091dafd39f 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.

drochner 8c0a9bab00 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.

bouyer 76c414a957 Add support for ext2fs, this needed a few modifications to ufs/ufs/inode.h:
- added an "union inode_ext" to struct inode, for the per-fs extentions.
  For now only ext2fs uses it.
- i_din is now an union:
	union {
		struct  dinode ffs_din; /* 128 bytes of the on-disk dinode. */
		struct ext2fs_dinode e2fs_din; /* 128 bytes of the on-disk dinode. */
	} i_din
  Added a lot of #define i_ffs_* and i_e2fs_* to access the fields.
- Added two macros: FFS_ITIMES and EXT2FS_ITIMES. ITIMES calls the rigth
  macro, depending on the time of the inode. ITIMES is used where necessary,
  FFS_ITIMES and EXT2FS_ITIMES in other places.

cgd 90688fce27 Change the second and third args to struct vfsops' (*vfs_mount)() to
'const char *', and 'void *', respectively.  The second arg is taken directly
from user arguments, and is const there, so must be const in the prototypes
and functions.  The third arg is also taken directly from user arguments.
It doesn't have to be changed, but since it's cleaner to keep the type
the same as the user arg's type, and I'm already making the 'const char *'
change...

is ebe1c82eda Make the struct lfs 512 bytes long on 32bit machines whose compiler doesn't
align 32bit integers. Use explicit sized typing at some other places.

XXX This still won't fix lfs for 64bit machines, as we have some
assumptions about sizeof(pointer)=sizeof(u_int32_t) in here, and (if I
looked right) a misaligned u_int64_t. The right fix (to cite cgd) will
be to seperate on-disk-representation from in-core, but I don't have
the time (at the moment) to do this.

cgd f6e4567c57 cast int64_t-sized types to "long long" before printing them with %qd.
gcc thinks that the 'q' modifier describes a "long long", and so -Wformat
whines when printing with 'q' on the alpha, since int64_t-sized types are
done with variations on "long" rather than "long long".
