925692caa5 - Significantly reduce the number of preallocated pv entries in
pmap_init().  Such a large preallocation is unnecessary and wastes
   nearly eight megabytes of kernel virtual address space per gigabyte
   of managed physical memory.
 - Increase UMA_BOOT_PAGES by two.  This enables the removal of
   pmap_pv_allocf().  (Note: this function was only used during
   initialization, specifically, after pmap_init() but before
   pmap_init2().  During pmap_init2(), a new allocator is installed.)

70005bdb38 Add just enough of i386/include/pcvt_ioctl.h to amd64/include/pcvt_ioctl.h
such that 'ispcvt' can build.  Unforunately 'ispcvt' is needed in order for
/etc/rc.d/syscons to run.  This fixes the bug where I could not get my
keymap effective at boot.

3db6450423 Reconfigure the runq macros to use the 64 bit ffs/bsf routines instead
of doing a loop and taking two 32 bit passes at the runqueue bits.  All
the 64 bit platforms should probably do this since there are 64 run queues.

62b689edc9 Kill the ASM versions of the mtx_lock_spin and friends. They were never

42f5377536 Revert some amd64 changes that cached curthread and converge back to the
i386 version.  The curthread special case in pcpu.h solves my complaint
about the verbose macro expansion in this case.  Note that the i386
version still has some OBE comments, I didn't re-add them back again.

b6c71225a9 Fix all users of mp_maxid to use the same semantics, namely:

9972cccea4 Argh! The Athlon64 and Opteron only implement 40 bits of address space in
the MTRR Base/Mask registers.  If you use the documented algorithm in the
systems programming guide, you'll get a GPF. The only thing that has
prevented this so far is that the bios pre-sets some MTRR entries which
we mis-interpreted sufficiently to fool the memcontrol interface into
thinking all the address space was taken and therefore rejected XFree86's
requests.  However, not all bioses do this..  You get an insta-panic in
that case.  Grrr.  A better fix (dynamic mask) will happen by 5.3/5-stable
so that we automatically adapt to more than 40 physical bits.

798a45964d - Split cpu_mp_probe() into two parts. cpu_mp_setmaxid() is still called
very early (SI_SUB_TUNABLES - 1) and is responsible for setting mp_maxid.
  cpu_mp_probe() is now called at SI_SUB_CPU and determines if SMP is
  actually present and sets mp_ncpus and all_cpus.  Splitting these up
  allows an architecture to probe CPUs later than SI_SUB_TUNABLES by just
  setting mp_maxid to MAXCPU in cpu_mp_setmaxid().  This could allow the
  CPU probing code to live in a module, for example, since modules
  sysinit's in modules cannot be invoked prior to SI_SUB_KLD.  This is
  needed to re-enable the ACPI module on i386.
- For the alpha SMP probing code, use LOCATE_PCS() instead of duplicating
  its contents in a few places.  Also, add a smp_cpu_enabled() function
  to avoid duplicating some code.  There is room for further code
  reduction later since much of this code is also present in cpu_mp_start().
- All archs besides i386 still set mp_maxid to the same values they set it
  to before this change.  i386 now sets mp_maxid to MAXCPU.

68cd0cc3c4 Turn on NO_MIXED_MODE for amd64 generic. It turns out that all the
known samples of broken chipsets that needed mixed mode in the first place
are so broken (ie: locks up) that we can't use IO APIC mode at all and it
needs to be turned off in the bios.  So, the MIXED_MODE penalty on the
good chipsets gained nothing.

5dd883833c Provide a streamlined '#define curthread __curthread()' for amd64 to avoid
the compiler having to parse and optimize the PCPU_GET(curthread) so often.
__curthread() is an inline optimized version of PCPU_GET(curthread) that
knows that pc_curthread is at offset zero in the pcpu struct.  Add a
CTASSERT() to catch any possible changes to this.  This accounts for
just over a 1% wall clock speedup for total kernel compile/link time,
and 20% compile time speedup on some specific files depending on which
compile options are used.

b8aeddf146 Sync with i386.
- turn on SMP in generic
- add 'device atpic' - this is unconditional on i386, but certain nvidia
  based systems need to disable acpi because the reference bios seems to be
  hosed.  If acpi is disabled, we won't find the apic.  amd64 has the
  mptable code in a seperate compile option as well.
- turn sym back on, it doesn't fail to compile anymore.

0d2a298904 Initial landing of SMP support for FreeBSD/amd64.
- This is heavily derived from John Baldwin's apic/pci cleanup on i386.
- I have completely rewritten or drastically cleaned up some other parts.
  (in particular, bootstrap)
- This is still a WIP.  It seems that there are some highly bogus bioses
  on nVidia nForce3-150 boards.  I can't stress how broken these boards
  are.  I have a workaround in mind, but right now the Asus SK8N is broken.
  The Gigabyte K8NPro (nVidia based) is also mind-numbingly hosed.
- Most of my testing has been with SCHED_ULE.  SCHED_4BSD works.
- the apic and acpi components are 'standard'.
- If you have an nVidia nForce3-150 board, you are stuck with 'device
  atpic' in addition, because they somehow managed to forget to connect the
  8254 timer to the apic, even though its in the same silicon!  ARGH!
  This directly violates the ACPI spec.

   unnecessary field from struct sf_buf on the alpha, amd64, and ia64.
   Ultimately, we may eliminate struct sf_buf on those architecures

64bb257f0b Always install IDT entries for ATPIC interrupt sources. The APIC no
longer uses these interrupt vectors for its ISA interrupt pins, so these
entries will not be overwritten.  If we get a spurious interrupt from the
ATPIC when using the APIC, it will be treated as a stray interrupt instead
of causing a panic.
