325e13dd19 A kldsym(2) syscall prototype for extracting information from the in-kernel
linker.  This is intended to replace kvm_mkdb etc.  The first version
only does name->value lookups, but it's open ended.  value->name lookups
would probably be a good thing to do too.

It's been suggested to try and connect the symbol tables to sysctl (which
is probably a more flexible way of doing it if it's done right), but that
is far more complex and difficult than I was ready to have a shot at.

dd0b2081f4 Implemented zero-copy TCP/IP extensions via sendfile(2) - send a
file to a stream socket. sendfile(2) is similar to implementations in
HP-UX, Linux, and other systems, but the API is more extensive and
addresses many of the complaints that the Apache Group and others have
had with those other implementations. Thanks to Marc Slemko of the
Apache Group for helping me work out the best API for this.
Anyway, this has the "net" result of speeding up sends of files over
TCP/IP sockets by about 10X (that is to say, uses 1/10th of the CPU
cycles) when compared to a traditional read/write loop.

ecbb00a262 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

1f56217280 Fix the futimes/undelete/utrace conflict with other BSD's. Note that
the only common  usage of utrace (the possible problem with this
commit) is with malloc, so this should be a real problem.  Add
the various NetBSD syscalls that allow full emulation of their
development environment.

8a6472b723 Finish _POSIX_PRIORITY_SCHEDULING. Needs P1003_1B and
_KPOSIX_PRIORITY_SCHEDULING options to work.  Changes:

Change all "posix4" to "p1003_1b".  Misnamed files are left
as "posix4" until I'm told if I can simply delete them and add
new ones;

Add _POSIX_PRIORITY_SCHEDULING system calls for FreeBSD and Linux;

Add man pages for _POSIX_PRIORITY_SCHEDULING system calls;

Add options to LINT;

Minor fixes to P1003_1B code during testing.

c5b193bfba Retire LFS.
If you want to play with it, you can find the final version of the
code in the repository the tag LFS_RETIREMENT.

If somebody makes LFS work again, adding it back is certainly
desireable, but as it is now nobody seems to care much about it,
and it has suffered considerable bitrot since its somewhat haphazard
integration.

7b778b5e61 Make all file-system (MFS, FFS, NFS, LFS, DEVFS) related option new-style.
This introduce an xxxFS_BOOT for each of the rootable filesystems.
(Presently not required, but encouraged to allow a smooth move of option *FS
to opt_dontuse.h later.)

LFS is temporarily disabled, and will be re-enabled tomorrow.

996c772f58 This is the kernel Lite/2 commit. There are some requisite userland
changes, so don't expect to be able to run the kernel as-is (very well)
without the appropriate Lite/2 userland changes.

The system boots and can mount UFS filesystems.

Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
		Mount_std mounts will not work until the getfsent
		library routine is changed.

ac0ad63f37 Reduced #include spam in <sys/sysproto.h> and fixed things that depended
on it.

makesyscalls.sh:
This parsed $Id$.  Fixed(?) to parse $FreeBSD$.  The output is wrong when
the id is not expanded in the source file.

syscalls.master:
Fixed declaration of sigsuspend().  There are still some bogons and
spam involving sigset_t.
Use `struct foo *' instead of the equivalent `foo_t *' for some nfs and
lfs syscalls so that <sys/sysproto.h> doesn't depend on <sys/mount.h>.

e6c4b9ba32 Add the utrace(caddr_t addr,size_t len) syscall, that will store the
data pointed at in a ktrace file, if this process is being ktrace'ed.
I'm using this to profile malloc usage.
The advantage is that there is no context around this call, ie, no
open file or socket, so it will work in any process, and you can
decide if you want it to collect data or not.

93915a2ac4 Fixed the args list for mount(). We're not ready for the BSD4.4lite2/
NetBSD interface.

Increased the bogusness of the args list for mmap().  The args lists for
most of the memory mapping functions are bogus.  The args lists in
syscalls.master are a little better than the ones in the args structs
currently being used, but the improvement for mmap() changed the object
code and I don't want to worry about that now.

Increased the bogusness of the args list for fcntl.  BSD4.4lite2/NetBSD
uses `void *' instead of int for the third arg.  This has the advantage
of working when `void *'s are longer than ints, but requires extra bogus
casts that I hope to avoid.

Fixed the args list for uname.  `struct outsname' seems to be a typo,
not an old interface.

Added comments about bogus args lists for open, mount, msync, munmap,
mprotect, madvise, mincore, fcntl, semsys, msgsys and shmsys.

f171307e84 Add new functionality to makesyscalls.sh:
o  optional config-file to set vars: sysnames, sysproto, sysproto_h,
	syshdr, syssw, syshide, syscallprefix, switchname, namesname, sysvec.
  o  change syntax of syscalls.master entry:
	remove argument count.
	add pseudo-prototype field defining function name and arguments.
  o  generates correct structure definitions for all system calls
	in sys/sysproto.h
  o  add type NOARGS:  same as STD except do not create structure in
	sys/sysproto.h
  o  add type NOPROTO:  same as STD except do not create structure or function
	prototype in sys/sysproto.h

New functionality provides complete prototype definitions.
Usefull for generating files for emulated systems like my new ibcs2 code.

Update syscalls.master to reflect new changes.  For example, read()
entry now looks like:

3	STD	POSIX	{ int ibcs2_read(int fd, char *buf, u_int nbytes); }

This is similar to how NetBSD generates these files.

3cb43dbdaf Generate prototypes for syscall-implementing functions. Put them in

Don't put $Id in generated files.

kern/syscalls.master:
I had to add some new fields to describe some non-orthogonal names.
E.g., the args struct for the syscall-implementing function foo()
is usually named `foo_args', but for getpid() it is named `args'.

sys/sysent.h:
sy_call_t is still incomplete to hide a couple of warnings.

3f31c649d1 Redo Kernel NTP PLL support, kernel side.
This code is mostly taken from the 1.1 port (which was in turn taken from
Dave Mills's kern.tar.Z example).  A few significant differences:

1) ntp_gettime() is now a MIB variable rather than a system call.  A few
fiddles are done in libc to make it behave the same.

2) mono_time does not participate in the PLL adjustments.

3) A new interface has been defined (in <machine/clock.h>) for doing
possibly machine-dependent things around the time of the clock update.
This is used in Pentium kernels to disable interrupts, set `time', and
reset the CPU cycle counter as quickly as possible to avoid jitter in
microtime().  Measurements show an apparent resolution of a bit more than
8.14usec, which is reasonable given system-call overhead.
