_NO_NAMESPACE_POLLUTION ifndef.  I've not renamed anything yet, but

Drop _MACHINE_ARCH and _MACHINE defines (not to be confused with
MACHINE_ARCH and MACHINE).  Their purpose was to be able to test
in cpp(1), but cpp(1) only understands integer type expressions.
Using such unsupported expressions introduced a number of subtle
bugs, which were discovered by compiling with -Wundef.

Changes since revision 1.33: +2 -0 lines
Implement preemption of kernel threads natively in the scheduler rather
than as one-off hacks in various other parts of the kernel:
- Add a function maybe_preempt() that is called from sched_add() to
  determine if a thread about to be added to a run queue should be
  preempted to directly.  If it is not safe to preempt or if the new
  thread does not have a high enough priority, then the function returns
  false and sched_add() adds the thread to the run queue.  If the thread
  should be preempted to but the current thread is in a nested critical
  section, then the flag TDF_OWEPREEMPT is set and the thread is added
  to the run queue.  Otherwise, mi_switch() is called immediately and the
  thread is never added to the run queue since it is switch to directly.
  When exiting an outermost critical section, if TDF_OWEPREEMPT is set,
  then clear it and call mi_switch() to perform the deferred preemption.
- Remove explicit preemption from ithread_schedule() as calling
  setrunqueue() now does all the correct work.  This also removes the
  do_switch argument from ithread_schedule().
- Do not use the manual preemption code in mtx_unlock if the architecture
  supports native preemption.
- Don't call mi_switch() in a loop during shutdown to give ithreads a
  chance to run if the architecture supports native preemption since
  the ithreads will just preempt DELAY().
- Don't call mi_switch() from the page zeroing idle thread for
  architectures that support native preemption as it is unnecessary.
- Native preemption is enabled on the same archs that supported ithread
  preemption, namely alpha, i386, and amd64.

This change should largely be a NOP for the default case as committed
except that we will do fewer context switches in a few cases and will
avoid the run queues completely when preempting.

Migrate the thread stack management functions from the machine-dependent
to the machine-independent parts of the VM.  At the same time, this
introduces vm object locking for the non-i386 platforms.

Two details:

1. KSTACK_GUARD has been removed in favor of KSTACK_GUARD_PAGES.  The
different machine-dependent implementations used various combinations
of KSTACK_GUARD and KSTACK_GUARD_PAGES.  To disable guard page, set
KSTACK_GUARD_PAGES to 0.

2. Remove the (unnecessary) clearing of PG_ZERO in vm_thread_new.  In
5.x, (but not 4.x,) PG_ZERO can only be set if VM_ALLOC_ZERO is passed
to vm_page_alloc() or vm_page_grab().

Fix the osf1 abi module  on SMP systems by making the size of
a struct pmap be the same on both SMP and UP kernels.

It turns out that the size of a struct pmap is much larger on alpha
SMP systems due to the number of pm_asn's being dependant on MAX_CPU.
Since modules are supposed to be SMP agnostic, this has the affect of
moving around the "interesting bits" of the vmspace (daddr, dsize)
that the osf1 module wants to frob.  So the module ends up scribbling in a
pmap struct, and the user either sees a panic, or an application failure.

While here, I've also shrunk MAXCPU to 8 now that it affects the size
of pmap structs on UP systesm.  This should be plenty, as I'm
unware of any hardware we currently run in which supports more than 8
CPUs.

Initiate deorbit burn for the i386-only a.out related support.  Moves are
under way to move the remnants of the a.out toolchain to ports.  As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL.  It has already lasted WAY beyond
that.

Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.

Fix CMSG and ALIGN macro usage.
Previously we had to include <machine/param.h> or <sys/param.h> bogusly
due to the fact that <sys/socket.h> CMSG macros needed the ALIGN macro,
which was defined in param.h.  However, including param.h was a disaster
for namespace pollution.
This solution, as contributed by shin a while ago, fixes it elegantly
by wrapping the definitions around some namespace pollution preventer
definitions.
This patch was long overdue.
This should allow any network programmer to use <sys/socket.h> as
before.

include:

* Interrupts are run in their own separate kernel threads and can be

alpha/include/param.h: #define NCPUS 1
alpha/include/lock.h: remove nop simplelock macros, which are defined
in <sys/lock.h> if NCPUS == 1.

As a result, NULL_SIMPLELOCK is defined, and a few warnings removed.

Don't define NMBCLUSTERS here.
It will be defined as appropriate value depending on maxusers.

Don't define MACHINE, MACHINE_ARCH, _MACHINE or _MACHINE_ARCH if
already defined.  This allows for cross building to work because we
need to lie to make to tell it to use the target names rather than the
host names.

This should have no effect on either architecture.  I've confirmed
that the intel build by make buildworld's for the past 3 months.

Introduce machine-dependent macro pgtok() to convert page count to number
of kilobytes. Its definition for each architecture could be optimized to
avoid potential numerical overflows.

Add a new library function getobjformat().  It checks all the
standard places ("/etc/objformat", ${OBJFORMAT}, argv) for an
indication of the user's preferred object file format.  This
consolidates some code that was starting to be duplicated in more
and more places.

Use the new function in ldconfig.

Note: I don't think that gcc should use getobjformat(), even though
it could.  The compiler should limit itself to functions that are
widespread, to ease porting and cross-compilation.

Major changes to the generic device framework for FreeBSD/alpha:

* Eliminate bus_t and make it possible for all devices to have
  attached children.

* Support dynamically extendable interfaces for drivers to replace
  both the function pointers in driver_t and bus_ops_t (which has been
  removed entirely.  Two system defined interfaces have been defined,
  'device' which is mandatory for all devices and 'bus' which is
  recommended for all devices which support attached children.

* In addition, the alpha port defines two simple interfaces 'clock'
  for attaching various real time clocks to the system and 'mcclock'
  for the many different variations of mc146818 clocks which can be
  attached to different alpha platforms.  This eliminates two more
  function pointer tables in favour of the generic method dispatch
  system provided by the device framework.

Future device interfaces may include:

* cdev and bdev interfaces for devfs to use in replacement for specfs
  and the fixed interfaces bdevsw and cdevsw.

* scsi interface to replace struct scsi_adapter (not sure how this
  works in CAM but I imagine there is something similar there).

* various tailored interfaces for different bus types such as pci,
  isa, pccard etc.

Add initial support for the FreeBSD/alpha kernel.  This is very much a
work in progress and has never booted a real machine.  Initial
development and testing was done using SimOS (see
http://simos.stanford.edu for details).  On the SimOS simulator, this
port successfully reaches single-user mode and has been tested with
loads as high as one copy of /bin/ls :-).

Obtained from: partly from NetBSD/alpha

Import NetBSD/Alpha headers needed to get the FreeBSD userland to compile
(and even run). These files don't necessarily make sense for a
FreeBSD/Alpha kernel build. That will come later and these files
will be changed accordingly.

These are a few of the alpha machine dependent header files - the first
referenced by the build of user-space libraries. These files were
obtained from NetBSD (with ansi.h being modified to reflect the FreeBSD
off_t and pid_t implementation).
