6412c65cf0 Add optimized block copy and zero functions using vis instructions, which
can do 64 bytes at a time and don't allocate lines in the L2 cache.  These
assume that everything is 64 byte aligned, and that there's more than 128
bytes of data (best for whole pages).  The block load and store instructions
don't follow normal memory ordering rules and require either a memory barrier
or move between registers before the data can actually be used.  This
implementation correctly shuffles around 3 out of the 4 sets of registers
in order to avoid memory barriers expect for the last 2 blocks.

937e05327e Add support for saving and restoring kernel floating point state. The state
will be saved if we context switch as a result of an interrupt which occured
while using the floating point registers in the kernel (which actually can't
happen right now).  This allows fp disabled traps in the kernel, which
normally shouldn't happen, so make sure the trapping code is what we expect
it is.

7dafcb6914 - Add space for kernel floating point registers to the pcb. These will be
used to support block copy and zero operations in the kernel which use the
  floating point registers.
- While I'm changing the size, improve the layout of struct pcb, sort by size,
  then alphabetical etc.
- Add some assertions to validate assumptions made about how the pcb is
  allocated.

8e4f1e2b8a - Generally improve register usage in cpu_switch. Use the 'in' registers
for temporaries relating to the state of the new process instead of the
  outs, so that functions can be called without fear of clobbering them.
- Use savefpctx instead of rolling our own.

3226556327 Kill aout to elf upgrade path. From an old comment in the makefile:
# If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will
# update the legacy support for aout. This includes all libraries, ld.so
# and boot objects. This part of build should be regarded as
# deprecated and you should _not_ expect to be able to do this past the
# release of 4.0. You have exactly one major release to move entirely
# to elf.

Now that we're past 5.0, these aren't needed at all anymore and it is
well past its freshness date.

02a0965ef6 MFp4 @27667: WARNS=5 cleanup on i386.
Remove the unused FILE\ *tf from print_mesg args, and the
    bogus passing in of an uninitialised FILE* for it.

    Call a timeval 'now' instead of 'clock' due to shadowing.

    Remove a nested localtime declaration.

    Make the delete invite argument match the ID type, u_int32_t.

    Use const for pointers to const items.

    Cast to long where printing as such.

    Include netinet/in.h for htonl/htons.

55ad402a8f - Pass a ucontext_t to _set_curthread. If non-NULL the new thread is set
as curthread in the new context, so that it will be set automatically when
  the thread is switched to.  This fixes a race where we'd run for a little
  while with curthread unset in _thread_start.

cc66ebe2a9 Commit a partial lazy thread switch mechanism for i386. it isn't as lazy
as it could be and can do with some more cleanup.  Currently its under
options LAZY_SWITCH.  What this does is avoid %cr3 reloads for short
context switches that do not involve another user process.  ie: we can
take an interrupt, switch to a kthread and return to the user without
explicitly flushing the tlb.  However, this isn't as exciting as it could
be, the interrupt overhead is still high and too much blocks on Giant
still.  There are some debug sysctls, for stats and for an on/off switch.

The main problem with doing this has been "what if the process that you're
running on exits while we're borrowing its address space?" - in this case
we use an IPI to give it a kick when we're about to reclaim the pmap.

Its not compiled in unless you add the LAZY_SWITCH option.  I want to fix a
few more things and get some more feedback before turning it on by default.

This is NOT a replacement for Bosko's lazy interrupt stuff.  This was more
meant for the kthread case, while his was for interrupts.  Mine helps a
little for interrupts, but his helps a lot more.

The stats are enabled with options SWTCH_OPTIM_STATS - this has been a
pseudo-option for years, I just added a bunch of stuff to it.

One non-trivial change was to select a new thread before calling
cpu_switch() in the first place.  This allows us to catch the silly
case of doing a cpu_switch() to the current process.  This happens
uncomfortably often.  This simplifies a bit of the asm code in cpu_switch
(no longer have to call choosethread() in the middle).  This has been
implemented on i386 and (thanks to jake) sparc64.  The others will come
soon.  This is actually seperate to the lazy switch stuff.

6ab0d6c220 When kill(-1) returns ESRCH, it could be because the current process
doesn't have a process group, which can occur if you're working with
a custom init that doesn't set up a full tty context.  Rather than
refusing to reboot, ignore ESRCH from the kill attempt in reboot(8).
