a51c9b6627 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.

Tested on: i386 (extensively), alpha

d13db8471c Align _BSD_CLK_TCK_ and _BSD_CLOCKS_PER_SEC_ with most other
platforms.  This introduces some binary incompatibilities for
dynamically linked programs which make use of clock(3) and times(3).

c3bdd669c3 Change hw.physmem and hw.usermem to unsigned long like they used to be
in the original hardwired sysctl implementation.

The buf size calculator still overflows an integer on machines with large
KVA (eg: ia64) where the number of pages does not fit into an int.  Use
'long' there.

Change Maxmem and physmem and related variables to 'long', mostly for
completeness.  Machines are not likely to overflow 'int' pages in the
near term, but then again, 640K ought to be enough for anybody.  This
comes for free on 32 bit machines, so why not?

d541375722 Move several MI types from <machine/_types.h> to <sys/_types.h>.
These types are unlikely to ever become very MD.  They include:
clockid_t, ct_rune_t, fflags_t, intrmask_t, mbstate_t, off_t, pid_t,
rune_t, socklen_t, timer_t, wchar_t, and wint_t.

While moving them, make a few adjustments (submitted by bde):
o __ct_rune_t needs to be precisely `int', not necessarily __int32_t,
  since the arg type of the ctype functions is int.
o __rune_t, __wchar_t and __wint_t inherit this via a typedef of
  __ct_rune_t.
o Some minor wording changes in the comment blocks for ct_rune_t and
  mbstate_t.

9e6f796b0d o Merge <machine/ansi.h> and <machine/types.h> into a new header
called <machine/_types.h>.
o <machine/ansi.h> will continue to live so it can define MD clock
  macros, which are only MD because of gratuitous differences between
  architectures.
o Change all headers to make use of this.  This mainly involves
  changing:
    #ifdef _BSD_FOO_T_
    typedef	_BSD_FOO_T_	foo_t;
    #undef _BSD_FOO_T_
    #endif
  to:

9f0ddc464e Create a new header <machine/_stdint.h> for storing MD parts of
<stdint.h>.  Previously, parts were defined in <machine/ansi.h> and
<machine/limits.h>.  This resulted in two problems:
  (1) Defining macros in <machine/ansi.h> gets in the way of that
      header only defining types.
  (2) Defining C99 limits in <machine/limits.h> adds pollution to
      <limits.h>.

cc7b2e4248 Infrastructure tweaks to allow having both an Elf32 and an Elf64 executable
handler in the kernel at the same time.  Also, allow for the
exec_new_vmspace() code to build a different sized vmspace depending on
the executable environment.  This is a big help for execing i386 binaries
on ia64.   The ELF exec code grows the ability to map partial pages when
there is a page size difference, eg: emulating 4K pages on 8K or 16K
hardware pages.

Flesh out the i386 emulation support for ia64.  At this point, the only
binary that I know of that fails is cvsup, because the cvsup runtime
tries to execute code in pages not marked executable.

Obtained from:  dfr (mostly, many tweaks from me).

ebfda4c0dd Move __offsetof() macro from <machine/ansi.h> to <sys/cdefs.h>. It's
hardly MD, since all our platforms share the same macro.  It's not
really compiler dependent either, but this helps in reducing
<machine/ansi.h> to only type definitions.

4830c34648 Move the "- 1" into the RQB_FFS(mask) macro itself so that
implementations can provide a base zero ffs function if they wish.
This changes
  #define RQB_FFS(mask) (ffs64(mask))
  foo = RQB_FFS(mask) - 1;
to
  #define RQB_FFS(mask) (ffs64(mask) - 1)
  foo = RQB_FFS(mask);
On some platforms we can get the "- 1" for free, eg: those that use the
C code for ffs64().

be8327ddfe Simplify IA64_CMPXCHG to avoid having braced-groups in expressions.
As a minor positive side-effect, code at -O0 is more optimal. As a
minor negative side-effect, certain boundary cases yield no better
code than non-boundary cases. For example, atomic_set_acq_32(p, 0)
does a useless logical OR with value 0. This was previously elimina-
ted as part of if/while optimizations. Non-boundary cases yield
identical code at -O1 and -O2.

49d0eba5f2 o Rename ia64_count_aps to ia64_count_cpus and reimplement the
function to return the total number of CPUs and not the highest
   CPU id.
o  Define mp_maxid based on the minimum of the actual number of
   CPUs in the system and MAXCPU.
o  In cpu_mp_add, when the CPU id of the CPU we're trying to add
   is larger than mp_maxid, don't add the CPU. Formerly this was
   based on MAXCPU. Don't count CPUs when we add them. We already
   know how many CPUs exist.
o  Replace MAXCPU with mp_maxid when used in loops that iterate
   over the id space. This avoids a couple of useless iterations.
o  In cpu_mp_unleash, use the number of CPUs to determine if we
   need to launch the CPUs.
o  Remove mp_hardware as it's not used anymore.
o  Move the IPI vector array from mp_machdep.c to sal.c. We use
   the array as a centralized place to collect vector assignments.
   Note that we still assign vectors to SMP specific IPIs in
   non-SMP configurations. Rename the array from mp_ipi_vector to
   ipi_vector.
o  Add IPI_MCA_RENDEZ and IPI_MCA_CMCV. These are used by MCA.
   Note that IPI_MCA_CMCV is not SMP specific.
o  Initialize the ipi_vector array so that we place the IPIs in
   sensible priority classes. The classes are relative to where
   the AP wake-up vector is located to guarantee that it's the
   highest priority (external) interrupt. Class assignment is
   as follows:
	class	IPI		notes
	x	AP wake-up	(normally x=15)
	x-1	MCA rendezvous
	x-2	AST, Rendezvous, stop
	x-3	CMCV, test

79ba8b4281 Add ar.lc and ar.ec to the trapframe. These are not saved for syscalls,
only for exceptions.

While adding this to exception_save and exception_restore, it was hard
to find a good place to put the instructions. The code sequence was
sufficiently arbitrarily ordered that the density was low (roughly 67%).
No explicit bundling was used.
Thus, I rewrote the functions to optimize for density (close to 80% now),
and added explicit bundles and nop instructions. The immediate operand
on the nop instruction has been incremented with each instance, to make
debugging a bit easier when looking at recurring patterns. Redundant
stops have been removed as much as possible. Future optimizations can
focus more on performance. A well-placed lfetch can make all the
difference here!

Also, the FRAME_Fxx defines in frame.h were mostly bogus. FRAME_F10 to
FRAME_F15 were copied from FRAME_F9 and still had the same index. We
don't use them yet, so nothing was broken.

c0e3147cc6 Tidy up some loose ends.
i386/ia64/alpha - catch up to sparc64/ppc:
- replace pmap_kernel() with refs to kernel_pmap
- change kernel_pmap pointer to (&kernel_pmap_store)
  (this is a speedup since ld can set these at compile/link time)
all platforms (as suggested by jake):
- gc unused pmap_reference
- gc unused pmap_destroy
- gc unused struct pmap.pm_count
(we never used pm_count - we track address space sharing at the vmspace)
