89ccb410d4 Correct spelling of "SHMMAXPGS" so the config override will actually work. 1993-10-09 15:29:04 +00:00

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.

b6c78fe436 define SHMMAXPGS where it is suppose to be, you can over ride this with 
a kernel config options "SHMAXPGS=xxx", default is currently 64 pages
due to limit kernel map space.

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

c26491ecf4 Increased default data size (DFLDSIZ) to 16MB. Need to rebuild libutil, 
kernel, ps and w for this to work!

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) */
