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)

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
due to limit kernel map space.

* 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

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