86360fee54 Remove thr_sleep and thr_wakeup. Remove fields p_nthread and p_wakeup
from struct proc, which are now unused (p_nthread already was).
Remove process flag P_KTHREADP which was untested and only set
in vfs_aio.c (it should use kthread_create).  Move the yield
system call to kern_synch.c as kern_threads.c has been removed
completely.

ac2b067b9a Change the 'exit()' system call to 'sys_exit()'. This avoids overlapping
gcc's internal exit() prototypes and the (futile) hackery that we did to
try and avoid warnings.  main() was renamed for similar reasons.
Remove an exit related hack from makesyscalls.sh.

aa4b7eae22 Fixed the declaration of mmap(). The crufty padding arg had the wrong
type.  This gave an inconsistent amount of crufty padding on i386's with
64-bit longs (8 bytes instead of 4).  On alphas it gives a consistent
amount of crufty padding (8 bytes) in addition to the 4 bytes of normal
padding caused by passing int args as register_t's.

Fixed the args struct tag for the NOPROTO syscalls (netbsd_lchown() and
netbsd_msync()).  The tag is currently unused for NOPROTO syscalls, so
the bug has no effect, but it will be used even in the NOPROTO case to
calculate sy_nargs correctly.

8ccd633455 Implement setres[ug]id() and getres[ug]id(). This has been sitting in
my tree for ages (~2 years) waiting for an excuse to commit it.  Now Linux
has implemented it and it seems that Staroffice (when using the
linux_base6.1 port's libc) calls this in the linux emulator and dies in
setup.  The Linux emulator can call these now.

da3605dbea sigset_t change (part 1 of 5)
-----------------------------

Rename sigaction, sigprocmask, sigpending and sigsuspend to
osigaction, osigprocmask, osigpending and osigsuspend (resp)
and add new syscalls for them to support the new sisgset_t
without breaking existing binaries.

Change the prototype of sigaltstack to use the typedef stack_t
instead of struct sigaltstack to reflect that it is SUSv2
compliant.

Also, rename sigreturn to osigreturn and add a new syscall
to support the modified stackframe. The change is caused by
sigreturn operating on ucontext_t now and the fact that
siginfo_t has been updated to conform to SUSv2.

f664346fbe Fixed nonsense arg type `const caddr_t' in the prototype() for utrace().
Changed to `const void *'.  utrace() is undocumented, so nothing should
notice.

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.

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.
