af5bf12239 Now that all system calls are MPSAFE, retire the SYF_MPSAFE flag used to
mark system calls as being MPSAFE:
- Stop conditionally acquiring Giant around system call invocations.
- Remove all of the 'M' prefixes from the master system call files.
- Remove support for the 'M' prefix from the script that generates the
  syscall-related files from the master system call files.
- Don't explicitly set SYF_MPSAFE when registering nfssvc.

92df1b8f6f Conditionally acquire Giant around the ISC and Xenix system calls based
on the SYF_MPSAFE flag in the wrapper system calls for the ISC and Xenix
system call vectors.

b40ce4165d KSE Milestone 2
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

6be523bca7 Add a new MI pointer to the process' trapframe p_frame instead of using
various differently named pointers buried under p_md.

cb226aaa62 Move the "retval" (3rd) parameter from all syscall functions and put
it in struct proc instead.

This fixes a boatload of compiler warning, and removes a lot of cruft
from the sources.

I have not removed the /*ARGSUSED*/, they will require some looking at.

libkvm, ps and other userland struct proc frobbing programs will need
recompiled.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

9e03db613c Remove old files no longer needed.
Add new files created for emulator.
Modify NetBSD import to work with FreeBSD and add new features and
code.  The complete emulator is essentially a combination of work/code
implemented by Sean Eric Fagan, Soren Schmidt, Scott Bartram, and myself,
Steven Wallace.

Features of this new emulator system include:

 o  "clean" code, including strict prototyping.
 o  Auto-generation of ibcs2 system calls, xenix system calls, isc system
calls.  Generation includes system tables, structure definitions,
and prototyping of function calls.
 o  ibcs2 emulator does not rely on any COMPAT_43 system calls.
 o  embedded socksys support
 o  ibcs2 msgsys, semsys, shmsys calls supported if supported in kernel
 o  alternate /emul/ibcs2 namespace searched first for files in ibcs2
system.  Usefull to keep sysv libraries, binaries in /emul/ibcs2.
 o  many other finer details and functions fixed or implemented.

125bd0c85c Don't depend on namespace pollution in <machine/limits.h> for the
definition of CLK_TCK.  Use _BSD_CLK_TCK_ instead of CLK_TCK so that
we don't have to include the user header <time.h>.

69b770e238 iBCS2 emulator core files.
This is the main files for the iBCS2 emulator. It can be use
compiled into the kernel by using:

options		IBCS2
options 	COMPAT_IBCS2

or as a lkm module using:

options		COMPAT_IBCS2

and then loading it via the ibcs2 script in /usr/bin

REMEMBER: this code is still experimental ! NO WARRENTY !
