d42d25c451 param.h:
Mark the fact that PGSHIFT and PDRSHIFT are really the same as
PG_SHIFT and PD_SHIFT, these should be collapsed some day soon.

Document that KERNBASE should really be KPTDPTDI << PDRSHIFT, for
now leave it as the constant 0xFE000000 until I make a seperate
common header file for this stuff (vmaddresses.h?)

Remove NKMEMCLUSTERS define, it was only being used to define
VM_KMEM_SIZE, so why have all the indirection.  Besides who wants
to work in CLBYTE sizes chuncks.


pmap.h:

Fix $Id$ and some other minor format clean ups.

Remove the XXX comment about NKPDE, since it now has the correct value
of 7.

Remove unused LASTPTDI and move the APTD into the very end of memory to
free up 4MB of kernel virtual address space.
Remove unused RSVDPTDI and free up 12MB of kernel virtual address space.


vmparam.h

Fix $Id$.

Increase SHMMAXPGS to 512 (2MB) now that there is room for it to be
bigger.  The XXX comment stays until the kernel moves down in memory
to free up enough space to use the proper default of 4MB.

VM_KMEM_SIZE is now a direct constant stating the size of the kernel
malloc region.  Increased the value from 3MB to 16MB.

988d75b3d6 Eliminate definition of I386_PAGE_SIZE and use NBPG instead
Cleaned up tabs vs spaces after #define to make file consistent.
Removed now unused definitions of I386_PAGE_SIZE and I386_PDR_SIZE

Note That these two where unused and had the wrong values anyway!
Changed I386_KPDES to NKPDE
Changed I386_UPDES to NUPDE

Redid constant assignments of *PTDI's to be sizeable and relative.

da73bf46a5 Fixed PHYSTOKV, addition operator on pointers is the wrong thing to do
here.  This is really a crock, but it works.

d529c3d85c Add PHYSTOKV used in scsi drivers with a correct definition based on
KERNBASE.

Change #define<tab> to #define<space> on lines that had it wrong

09f07fb057 All:
Remove patch kit headers, and add $Id$
	This is mostly to align some more code with NetBSD.

cpu.h:
	Remove the old function vs. include configuration stuff that was
	ifdefed out when we went to inline functions.
	Remove the define of resettodr that made it a nop, there is
	already a function that makes it a nop, no need to #define one.
	Remove the #defines of processor types, they are now defined
	in cputypes.h, #include that file.
	Add struct cpu_nameclass for support of cpu types.

frame.h:
	include sys/signal.h, it will be needed in the future.
	put the sigframe structure here that was in machdep.c

pcb.h:
	Add multiple inclusion protection.
	Add pcb_ldt and pcb_ldt_len to pcb structure, this is for the
	user mode ldt.

c77ba36045 Fix definitions to be in terms of a minimum number of constants by
using the SHIFT value as the basis for the other values, for example
instead of:
#define		NBPG		4096
#define		PGSHIFT		12
use:
#define		PGSHIFT		12
#define		NBPG		(1 << PGSHIFT)

89ec6ec6bf Removed patch kit header. Cleaned up tabbing and removed extra blank
lines to match NetBSD.  Added $Id$.
Added MID_MACHINE from NetBSD.
Removed definition of DELAY() for non-kernel soures.
Fixed some small english errors that had been corrected in NetBSD.
File is now identical to NetBSD's, but will be changing soon for some
of my clean up work.

a kernel config options "SHMAXPGS=xxx", default is currently 64 pages

269312019a * Applied fixes from Bruce Evans to fix COW bugs, >1MB kernel loading,
profiling, and various protection checks that cause security holes
  and system crashes.
* Changed min/max/bcmp/ffs/strlen to be static inline functions
  - included from cpufunc.h in via systm.h. This change
  improves performance in many parts of the kernel - up to 5% in the
  networking layer alone. Note that this requires systm.h to be included
  in any file that uses these functions otherwise it won't be able to
  find them during the load.
* Fixed incorrect call to splx() in if_is.c
* Fixed bogus variable assignment to splx() in if_ed.c

beb7ebb072 Added (protection) around negative constants, in case a program wants
to use the negative of that constant.

#define NEG_NUM -3
#define SAFE_NEG_NUM (-3)

i = -NEG_NUM;		/* Error --3 */
j = -SAFE_NEG_NUM	/* Okay -(-3) */
