9ef024f7b7 Add a crutch so that direct-mapped DMA works on alpha. This is a step 
toward preventing this driver from crashing an alpha at boot.

252bcf459d Give clearer diagnostics on some cases of invalid 
combinations of mdconfig(8) command-line arguments.

Make mdconfig(8) accept "-a -f file -o options"
equally with "-a -f file" (assuming "-t vnode".)

891619a66d Use bioq_flush() to drain a bio queue with a specific error code. 
Retain the mistake of not updating the devstat API for now.

Spell bioq_disksort() consistently with the remaining bioq_*().

#include <geom/geom_disk.h> where this is more appropriate.

cdcdfd877b Parallelize (on the top-level SUBDIR list) the "all" stage of 
buildworld.  This gives 5-11% percent gain in real buildworld
times on various UP and SMP systems here.  I used 4 * hw.ncpu
as an argument to "make -j" in my tests.

09139a4537 Implement support for RFC 3514 (The Security Flag in the IPv4 Header). 
(See: ftp://ftp.rfc-editor.org/in-notes/rfc3514.txt)

This fulfills the host requirements for userland support by
way of the setsockopt() IP_EVIL_INTENT message.

There are three sysctl tunables provided to govern system behavior.

	net.inet.ip.rfc3514:

		Enables support for rfc3514.  As this is an
		Informational RFC and support is not yet widespread
		this option is disabled by default.

	net.inet.ip.hear_no_evil

		 If set the host will discard all received evil packets.

	net.inet.ip.speak_no_evil

		If set the host will discard all transmitted evil packets.

The IP statistics counter 'ips_evil' (available via 'netstat') provides
information on the number of 'evil' packets recieved.

For reference, the '-E' option to 'ping' has been provided to demonstrate
and test the implementation.

f217a77ce4 - Rename pcb_fpstate to pcb_ufp (user floating point), and change it to

adaptation of libc_r for the thr system call interface.  This is beta
   quality code.

f27bf63b8a - Mark the various thr syscalls as MP safe. Previously there was a bug if 
this was not done since thr_exit() unwinds giant.

2c10d16a4b - Borrow the KSE single threading code for exec and exit. We use the check 
if (p->p_numthreads > 1) and not a flag because action is only necessary
   if there are other threads.  The rest of the system has no need to
   identify thr threaded processes.
 - In kern_thread.c use thr_exit1() instead of thread_exit() if P_THREADED
   is not set.

69404b5090 - Add an api for doing smp safe locks in userland. 
- umtx_lock() is defined as an inline in umtx.h.  It tries to do an
   uncontested acquire of a lock which falls back to the _umtx_lock()
   system-call if that fails.
 - umtx_unlock() is also an inline which falls back to _umtx_unlock() if the
   uncontested unlock fails.
 - Locks are keyed off of the thr_id_t of the currently running thread which
   is currently just the pointer to the 'struct thread' in kernel.
 - _umtx_lock() uses the proc pointer to synchronize access to blocked thread
   queues which are stored in the first blocked thread.

89bb1cef1d - Add two files to support the thr threading interface. 
- sys/thr.h contains the user space visible api that is intended only for
   use in threading library packages.
 - kern/kern_thr.c contains thr system calls and other thr specific code.
