e90d8494fb Kill the ASM versions of the mtx_lock_spin and friends. They were never
used on amd64, and were actually totally broken.  They had the wrong
calling conventions.  I believe the i386 versions are going away too.

9dc1f87f1b 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.

08335c63bf Rename mac_create_cred() MAC Framework entry point to mac_copy_cred(),
and the mpo_create_cred() MAC policy entry point to
mpo_copy_cred_label().  This is more consistent with similar entry
points for creation and label copying, as mac_create_cred() was
called from crdup() as opposed to during process creation.  For
a number of policies, this removes the requirement for special
handling when copying credential labels, and improves consistency.

3b8e185f65 Fix a deadlock between vm_fault() and vm_mmap(): The expected lock ordering
between vm_map and vnode locks is that vm_map locks are acquired first.  In
revision 1.150 mmap(2) was changed to pass a locked vnode into vm_mmap().
This creates a lock-order reversal when vm_mmap() calls one of the vm_map
routines that acquires a vm_map lock.  The solution implemented herein is
to release the vnode lock in mmap() before calling vm_mmap() and reacquire
this lock if necessary in vm_mmap().

bfe6af52a8 - Reorder the APIC enumerator SYSINIT's to register enumeators at
SI_SUB_CPU - 1 and probe enumerators, probe CPUs, and setup the local
  APIC programming all at SI_SUB_CPU / SI_ORDER_FIRST.  This is needed to
  help get the ACPI module working again as it moves the APIC enumeration
  code after SI_SUB_KLD.
- In the MADT parser, use mp_maxid rather than MAXCPU to terminate a loop
  when assigning per-cpu ACPI IDs to avoid a dependency on 'options SMP'.
- Allow the apic device to be disabled via 'hint.apic.0.disabled' from the
  loader.  Note that since this is done in the local APIC code, it works
  for both the ACPI and non-ACPI cases.

- Dynamically allocate the cpu_softc[] array based on mp_maxid instead of

- Use mp_maxid rather than MAXCPU when walking all the CPUs looking for a
  match.
- Always call smp_rendezvous() since UP kernels now provide this.
- Use mp_ncpus rather than cpu_ndevices when determining if we need to
  disable C3 for SMP machines.

907202ec1f Export a few SMP related symbols in UP kernels as well. This is needed to
aid other kernel code, especially code which can be in a module such as
the acpi_cpu(4) driver, to work properly with both SMP and UP kernels.
The exported symbols include mp_ncpus, all_cpus, mp_maxid, smp_started, and
the smp_rendezvous() function.  This also means that CPU_ABSENT() is now
always implemented the same on all kernels.

f6ae273bd0 Updated cx driver commit part 1: bring in the new kernel driver.
This is the vastly updated cx drvier from Roman Kurakin <rik@cronyx.ru>
who has been patiently waiting for this update for sometime.

The driver is mostly a rewrite from the version we have in the tree.
While some similarities remain, losing the little history that the old
driver has is not a big loss, and the re@ felt it was easier this way (less
error prone).

The userland parts of this update will be committed shortly.

The driver is not connected to the build yet.  I want to make sure I
don't break any platform at any time, so I want to test that with
these files in the tree before I continue (on the off chance I'm
forgetting a file).

I changed the DEBUG macro to CX_DEBUG from the code that was submitted
(to not break when we go to building with opt_global.h after the
release), as well adding $FreeBSD$.

ba4ca33c01 Fixed panics in apic interrupt handlers if kernel profiling is turned
on.  MCOUNT and FAKE_MCOUNT() may clobber all the call-used registers,
and one FAKE_MCOUNT() was placed so that an active %eax was clobbered.
The fix is to move this FAKE_MCOUNT() earlier where it should have
been anyway.

Fixed 3 layers of bitrot in the comment about why this FAKE_MCOUNT()
was where it was by removing the comment.  (mcount() should be called
as early as possible after entering a new level, but an implementation
detail got in the way until 3 layers of changes ago.)

Kernel profiling still gives wrong results because the new interrupt
code rearranged object files too much.  mcount() depends on trap,
syscall and interrupt handlers being between certain magic labels with
interrupt handlers last, and on nothing else being there.  Splitting
up exception.o moved the magic labels to effectively random places
relative to what they are supposed to delimit.  This mainly broke the
call graph; the flat profile is still usable.

68eb4e63a3 Fixed breakage of the pci case of the cy driver by the new interrupt
code.  Both the driver and the new code were wrong.  Driver interrupt
handlers are supposed to take "void *vsc" arg, but some including all
COMPAT_ISA drivers and the pci part of the cy driver want an "int unit"
arg.  They got this using bogus casts of function pointers which should
have kept working despite their bogusness.  However, the new interrupt
code doesn't honor requests to pass an arg of ((void *)0), so things
are very broken if the arg is actually a representation of unit 0.

The fix is to use a normal "void *vsc" arg for the pci case and a
wrapper for the COMPAT_ISA case (of the cy driver).  This cleans up
new-busification of the pci case but takes the COMPAT_ISA case a little
further from new-bus.  The corresponding bug for the COMPAT_ISA case
has already been fixed similarly using a wrapper in compat_isa.c and
we need another wrapper just to undo that.

Fixed some directly related style bugs (mainly by removing compatibility
cruft).

cy.c:
Fixed an indirectly related old bug in cyattach_common().  A wrong status
was returned in the unlikely event that malloc() failed.

3a0af1aae7 After extensive QA cycles at 3ware, bring the driver in-line with all the
issues which they found and asked to be changed so 3ware can offcially
support the driver.

Summary of the most significant changes:

- TWE_OVERRIDE is no longer supported
- If twe_getparam failed, bogus data would be returned to the caller
- Cache the device unit in the twe_drive structure to aid debugging
- Add the 3ware driver version.
- Proper return error codes for many functions.
- Track the minimum queue length statistics
- 4.x compat: use the cached unit number from the twe_drive structure
  instead of the the cached si_drv2.  3ware found that after many loads
  and unloads that si_drv2 became corrupted.  This did not happen in
  -current.

9d12741630 Fix Lucent cards.
o Back out workaround for not resetting lucent cards more than once.  With
  these fixes, it appaers they are no longer necessary.
o Set wi_gone when the card goes awol: typically when we get 0xffff back from
  the card.  Also, don't interact with a card that's gone, so we fail in
  seconds rather than minutes.  Also reduce amount of time we wait to .5s
  in wi_cmd.
o clear wi_gone on ifconfig down to give some cards a chance after they wedge
  (this appears to unwedge one of my prism cards with old firmware).  ifconfig
  up will fail quickly enough if the card really is out to lunch.
o Add delay in wi_init of 100ms.
o wi_stop(ifp, 0->1) changes so that we clear sc_enabled so that we
  exit out of the interrupt routine by just acking the interrupt

bc2791c3fa In dounmount(), only call checkdirs() prior to VFS_UNMOUNT() in the
forced unmount case. Otherwise, a file system that is referenced
only by process fd_cdir/fd_rdir references to the file system root
vnode will be successfully unmounted without the MNT_FORCE flag.

The previous behaviour was not compatible with the unmount semantics
required by amd(8), so file systems could be unexpectedly unmounted
while there were still references to the file system root directory.
