3713cbff75 Add support for the SIOCGIFHWADDR ioctl, commonly used by
license managers to obtain the host's ethernet address as
a key.

Note that this implementation takes the first hardware address for
the first ethernet interface found, and disregards the interface name
that may be passed in, as linux ethernet devices are all "ethX".

5856e12e69 Fully implement vfork. Vfork is now much much faster than even our
fork. (On my machine, fork is about 240usecs, vfork is 78usecs.)

Implement rfork(!RFPROC !RFMEM), which allows a thread to divorce its memory
	from the other threads of a group.

Implement rfork(!RFPROC RFCFDG), which closes all file descriptors, eliminating
	possible existing shares with other threads/processes.

Implement rfork(!RFPROC RFFDG), which divorces the file descriptors for a
	thread from the rest of the group.

Fix the case where a thread does an exec.  It is almost nonsense for a thread
	to modify the other threads address space by an exec, so we
	now automatically divorce the address space before modifying it.

d41979a063 Fix linux_getdents so that it can cope with filesystems which translate
the directory format (ext2fs, cd9660).  For these filesystems, it must use
cookies to find the correct offset to use for subsequent reads.  Without it,
linux /bin/ls tends to loop re-reading the same block over and over again.

2.2 candidate.

3f39dbc52d Removed potentially harmful garbage <vm/lock.h> and fixed bogus
use of it.  It was actually harmless because the use was null due
to fortuitous include orders and identical (wrong) idempotency

996c772f58 This is the kernel Lite/2 commit. There are some requisite userland
changes, so don't expect to be able to run the kernel as-is (very well)
without the appropriate Lite/2 userland changes.

The system boots and can mount UFS filesystems.

Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
		Mount_std mounts will not work until the getfsent
		library routine is changed.

bb65f5a1cc Fixed lseek() on named pipes. It always succeeded but should always fail.
Broke locking on named pipes in the same way as locking on non-vnodes
(wrong errno).  This will be fixed later.

The fix involves negative logic.  Named pipes are now distinguished from
other types of files with vnodes, and there is additional code to handle
vnodes and named pipes in the same way only where that makes sense (not
for lseek, locking or TIOCSCTTY).

66ff6a3c1b Add IP_OPTIONS and the multicast-related setsockopts to the
list of IP setsockopts the Linux emulator recognizes.

Explicitly disallow IP_HDRINCL since Linux's handling of
raw output is different than BSD's.

Closes PR#kern/2111.

aad9af2ba3 Removed nested include of <sys/proc.h> from <vm/vm_object.h> and fixed
the one place that depended on it.  wakeup() is now prototyped in
<sys/systm.h> so that it is normally visible.

Added nested include of <sys/queue.h> in <vm/vm_object.h>.  The queue
macros are a more fundamental prerequisite for <vm/vm_object.h> than
the wakeup prototype and previously happened to be included by
namespace pollution from <sys/proc.h> or elsewhere.

ede8dc43a2 Fixed unsigned longs that should have been vm_offset_t.
vm_offset_t is currently unsigned long but should probably be plain
unsigned for i386's to match the choice of minimal types to represent
for fixed-width types in Lite2.  Anyway, it shouldn't be assumed
to be unsigned long.

I only fixed the type mismatches that were detected when I changed
vm_offset_t to unsigned.  Only pointer type mismatches were detected.

6bc7cb8b3f Fix the getdents() emulation, the Linux ELF libraries use this, and
this code was not quite right (linux has a readdir and getdents syscall,
with the same args. readdir only returns one entry and uses a mutant
dirent structure.  This code was also returning the mutant form for
getdents as well.  My fault for missing this before.)
