__cachealign:

The __cachealign macro can be used for cache line aligning structures
of small to medium size.  It aligns the particular structure or
storage type to a system default cache line alignment, thus giving us
a much more better cache utilization by making the hardware work at
its best burst speeds.

__usereg:

The __usereg macro can/should be used when a function contains
arguments not more than 3.  It can be very useful to us due to the
message-passing nature of the kernel.

NOTE: I have not modified any other source files to make use of this
macro yet.  After I do some analysis, headers in sys/ which contain
small to medium sized structures will be modified to use the
__cachealign macro.

NOTE: No source files have been modified to make use of the __usereg
macro yet.  This process can be automated, because the maximum number
of arguments that apply to this macro is 3.

A significant number of applications need access to kernel data
structures.  Traditionally they have done a #define _KERNEL and
then #include'd the files.  Unfortunately this can create huge
conflicts between libc declarations and kernel declarations.  Also,

windup causing another unexpected header file to be included into such

This commit introduces _KERNEL_STRUCTURES.  A user program which needs
access to kernel data structures sets this instead of _KERNEL.  This
define will cause the kernel data structure but not the inlines or

SLAB ALLOCATOR Stage 1.  This brings in a slab allocator written from scratch
by your's truely.  A detailed explanation of the allocator is included but
first, other changes:

* Instead of having vm_map_entry_insert*() and friends allocate the
  vm_map_entry structures a new mechanism has been emplaced where by
  the vm_map_entry structures are reserved at a higher level, then
  expected to exist in the free pool in deep vm_map code.  This preliminary
  implementation may eventually turn into something more sophisticated that
  includes things like pmap entries and so forth.  The idea is to convert
  what should be low level routines (VM object and map manipulation)
  back into low level routines.

* vm_map_entry structure are now per-cpu cached, which is integrated into
  the the reservation model above.

* The zalloc 'kmapentzone' has been removed.  We now only have 'mapentzone'.

* There were race conditions between vm_map_findspace() and actually
  entering the map_entry with vm_map_insert().  These have been closed
  through the vm_map_entry reservation model described above.

* Two new kernel config options now work.  NO_KMEM_MAP has been fleshed out
  a bit more and a number of deadlocks related to having only the kernel_map
  now have been fixed.  The USE_SLAB_ALLOCATOR option will cause the kernel
  to compile-in the slab allocator instead of the original malloc allocator.
  If you specify USE_SLAB_ALLOCATOR you must also specify NO_KMEM_MAP.

* vm_poff_t and vm_paddr_t integer types have been added.  These are meant
  to represent physical addresses and offsets (physical memory might be
  larger then virtual memory, for example Intel PAE).  They are not heavily
  used yet but the intention is to separate physical representation from
  virtual representation.

    SLAB ALLOCATOR FEATURES

The slab allocator breaks allocations up into approximately 80 zones based
on their size.  Each zone has a chunk size (alignment).  For example, all
allocations in the 1-8 byte range will allocate in chunks of 8 bytes.  Each
size zone is backed by one or more blocks of memory.  The size of these
blocks is fixed at ZoneSize, which is calculated at boot time to be between
32K and 128K.  The use of a fixed block size allows us to locate the zone
header given a memory pointer with a simple masking operation.

The slab allocator operates on a per-cpu basis.  The cpu that allocates a
zone block owns it.  free() checks the cpu that owns the zone holding the
memory pointer being freed and forwards the request to the appropriate cpu
through an asynchronous IPI.  This request is not currently optimized but it
can theoretically be heavily optimized ('queued') to the point where the
overhead becomes inconsequential.  As of this commit the malloc_type
information is not MP safe, but the core slab allocation and deallocation
algorithms, non-inclusive the having to allocate the backing block,
*ARE* MP safe.  The core code requires no mutexes or locks, only a critical
section.

Each zone contains N allocations of a fixed chunk size.  For example, a
128K zone can hold approximately 16000 or so 8 byte allocations.  The zone
is initially zero'd and new allocations are simply allocated linearly out
of the zone.  When a chunk is freed it is entered into a linked list and
the next allocation request will reuse it.  The slab allocator heavily
optimizes M_ZERO operations at both the page level and the chunk level.

The slab allocator maintains various undocumented malloc quirks such as
ensuring that small power-of-2 allocations are aligned to their size,
and malloc(0) requests are also allowed and return a non-NULL result.
kern_tty.c depends heavily on the power-of-2 alignment feature and ahc
depends on the malloc(0) feature.  Eventually we may remove the malloc(0)
feature.

    PROBLEMS AS OF THIS COMMIT

NOTE!  This commit may destabilize the kernel a bit.  There are issues
with the ISA DMA area ('bounce' buffer allocation) due to the large backing
block size used by the slab allocator and there are probably some deadlock
issues do to the removal of kmem_map that have not yet been resolved.
