261e267ac2 Fix the assembler so that it produces object files with the correct
magic number byte ordering for FreeBSD.  This makes "file" describe
our object files as "FreeBSD/i386 object" instead of as NetBSD
object files.  In case this seems drastic and risky, Bruce points
out that the "ld -r -x" step that is done on every object file when
building libraries fixes the byte ordering in the same way.  I have
been running with this patch for over a month and have seen no
problems.

2a42fd0952 Add LBA mode support for large drives.
Use config flags 0x1000 to enable LBA mode. It should be enabled in
the BIOS too to avoid geometry confusion.

One catch though, I'm not sure all BIOS's uses the 64head/63secs
translation, all mine does but....

9d24fe0e45 - Fix bug I introduced a few months ago. If a driver fails the probe,
correctly unregister the interrupt from the system.

[ My fix is much simpler than the one provided in the PR ]

that `fsck -p' doesn't check multiple slices on the same drive
concurrently.  Don't invoke undefined behaviour when searching for
the drive number in strange device names.

193afe0189 Use a different errno (ELOOP (as sef mentioned) since the text that goes
with the error sounds ok for the condition) if O_NOFOLLOW gets a link.

0fdc628b41 Rather than let users get fd's to symlink files, make O_NOFOLLOW cause
an error if it gets a link (like it does if it gets a socket).  The
implications of letting users try and do file operations on symlinks
themselves were too worrying.

a66ae6f438 Back this out, allowing users to get a fd connected to a symlink is

b587fd008d Don't panic if a VOP_READ() gets through on a short link, Just Do It
(because we can :-).  This means you can open a link file (or pseudo-file
in the case of short links where the data is stored in the inode rather
than disk blocks) and read the contents.
However, trap any writes from the user as it's difficult to do the right
thing in all cases.  A link may be short and the user may be trying to
extend it beyond the limit and so on.  Although.. being able to re-target
a symlink without deleting it first might have been nice.
This stuff is a bit perverse since symlink() and readlink() calls can
end up actually being implemented as read/write vnode ops.

7e3426aa1f Implement a new open(2) flag: O_NOFOLLOW. This will instruct open
to not follow symlinks, but to open a handle on the link itself(!).
As strange as this might sound, it has several useful applications
safe race-free ways of opening files in hostile areas (eg: /tmp, a mode
1777 /var/mail, etc).  It also would allow things like fchown() to work
on the link rather than having to implement a new syscall specifically for
that task.

eb1c943900 Add a new -F flag which is a superset of -f. It will cause tail to
stat() the file being followed and do a close/reopen if the file has been
renamed and/or rotated.  This is damn useful for leaving running on files
in /var/log when newsyslog(8) rotates them.
