aa9aa68d2f Use PCPU_LAZY_INC() for cnt.v_{intr,trap,syscalls} rather than atomic
operations in some places and simple non-per CPU math in others.

99e9dcb817 Remove sched_free_thread() which was only used
in diagnostics. It has outlived its usefulness and has started
causing panics for people who turn on DIAGNOSTIC, in what is otherwise
good code.

a30ec4b99c Make sigaltstack as per-threaded, because per-process sigaltstack state
is useless for threaded programs, multiple threads can not share same
stack.
The alternative signal stack is private for thread, no lock is needed,
the orignal P_ALTSTACK is now moved into td_pflags and renamed to
TDP_ALTSTACK.
For single thread or Linux clone() based threaded program, there is no
semantic changed, because those programs only have one kernel thread
in every process.

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.

e46fe241d3 Stop pretending to support kernel profiling. The FAKE_MCOUNT() etc
calls are just gradually getting more and more stale.  At this point it
would be better to start from scratch once prof_machdep.c is adapted.

4cd2d525e3 Move a MD 32 bit binary support routine into the MD areas. exec_setregs
is highly MD in an emulation environment since it operates on the host
environment.  Although the setregs functions are really for exec support
rather than signals, they deal with the same sorts of context and include
files.  So I put it there rather than create yet another file.

c639ca93f4 Initial sweep at dividing up the generic 32bit-on-64bit kernel support
from the ia32 specific stuff.  Some of this still needs to move to the MI
freebsd32 area, and some needs to move to the MD area.  This is still
work-in-progress.

better that way when sigaction() and sigreturn() do the right thing.

9f0c4ab393 Deal with the user VM space expanding. 32 bit applications do not like
having their stack at the 512GB mark.  Give 4GB of user VM space for 32
bit apps.  Note that this is significantly more than on i386 which gives
only about 2.9GB of user VM to a process (1GB for kernel, plus page
table pages which eat user VM space).

c0a54ff621 Collect the nastiness for preserving the kernel MSR_GSBASE around the
load_gs() calls into a single place that is less likely to go wrong.

Eliminate the per-process context switching of MSR_GSBASE, because it
should be constant for a single cpu.  Instead, save/restore it during
the loading of the new %gs selector for the new process.

d85631c4ac Add BASIC i386 binary support for the amd64 kernel. This is largely
stolen from the ia64/ia32 code (indeed there was a repocopy), but I've
redone the MD parts and added and fixed a few essential syscalls.  It
is sufficient to run i386 binaries like /bin/ls, /usr/bin/id (dynamic)
and p4.  The ia64 code has not implemented signal delivery, so I had
to do that.

Before you say it, yes, this does need to go in a common place.  But
we're in a freeze at the moment and I didn't want to risk breaking ia64.
I will sort this out after the freeze so that the common code is in a
common place.

On the AMD64 side, this required adding segment selector context switch
support and some other support infrastructure.  The %fs/%gs etc code
is hairy because loading %gs will clobber the kernel's current MSR_GSBASE
setting.  The segment selectors are not used by the kernel, so they're only
changed at context switch time or when changing modes.  This still needs
to be optimized.

fe8cdcae87 - Replace inline implementations of sigprocmask() with calls to
kern_sigprocmask() in the various binary compatibility emulators.
- Replace calls to sigsuspend(), sigaltstack(), sigaction(), and
  sigprocmask() that used the stackgap with calls to the corresponding
  kern_sig*() functions instead without using the stackgap.

fd7a8150fb o In struct prison, add an allprison linked list of prisons (protected
by allprison_mtx), a unique prison/jail identifier field, two path
  fields (pr_path for reporting and pr_root vnode instance) to store
  the chroot() point of each jail.
o Add jail_attach(2) to allow a process to bind to an existing jail.
o Add change_root() to perform the chroot operation on a specified
  vnode.
o Generalize change_dir() to accept a vnode, and move namei() calls
  to callers of change_dir().
o Add a new sysctl (security.jail.list) which is a group of
  struct xprison instances that represent a snapshot of active jails.

bc5245d94c Add a placeholder for the execve_mac() system call, similar to SELinux's
execve_secure() system call, which permits a process to pass in a label
for a label change during exec.  This permits SELinux to change the
label for the resulting exec without a race following a manual label
change on the process.  Because this interface uses our general purpose
MAC label abstraction, we call it execve_mac(), and wrap our port of
SELinux's execve_secure() around it with appropriate sid mappings.
