fba73571bd For Pentium machines, use a faster version of microtime with 8 usec 
resolution (can probably be improved somewhat).  Other machines take
a three-instruction hit if I586_CPU is defined, none otherwise.

4c5483f462 Initialize lockf pointer. I missed this when I made NFS use the generic 
advlock mechanism, and not doing so results in random system crashes.

9ae159169a Make it easier for programs to figure out what revision of FreeBSD they 
are running under.  Here's how to bootstrap (order is important):

1) Re-compile gcc (just the driver is all you need).
2) Re-compile libc.
3) Re-compile your kernel.  Reboot.
4) cd /usr/src/include; make install

You can now detect the compilation environment with the following code:

#if !defined(__FreeBSD__)
#define __FreeBSD_version 199401
#elif __FreeBSD__ == 1
#define __FreeBSD_version 199405
#else
#include <osreldate.h>
#endif

You can determine the run-time environment by calling the new C library
function getosreldate(), or by examining the MIB variable kern.osreldate.

For the time being, the release date is defined as 199409, which we have
already established as our target.

2e0cc1821d Some programs (like GNU configure programs) depend on the output of 
`uname -s' to be something reasonable (traditionally, `i386') rather
than `PC-Class'.  Make it so.

4b43e1d8ca Removed some padding bytes from the nfsnode struct to make the structure 
size a power of 2 again. The system complains otherwise - probably because
it wastes space with our malloc scheme otherwise.

92a34c0c6d Removed an old, obsolete call to vmmeter(). This is called now in the 
schedcpu() routine in kern/kern_synch.c. This extra call to vmmeter() in
vm_glue.c was what was totally messing up the load average calculations.

92dc7331c9 Made lockf advisory locking code generic (rather than ufs specific), and 
use it in NFS. This is required both for diskless support and for POSIX
compliance. Note: the support in NFS is only for the local node.
