Get Ready, the port to Linux/Alpha is well on its way....
Next is RVM and RPC2.  Coda Porting is definitely a therapeutic break
from my DCE work. Maybe once I hand the work off to Peter to help cleanup
Venus for 64-bits, I can go port the Minicache VFS to Solaris, hows that
for a deal?

- I've fixed the 64-bit problems in the Linux VFS module.  The module
  now loads through insmod and I see this. This doesnt mean anything,
  it could still panic when tickled further.

	jrd_at_italpha1$ more /proc/filesystems 
	        ext2
	        msdos
	nodev   proc
	nodev   nfs
	        iso9660
	nodev   coda

This shows up in the messages log:

- I've ported the LWP library to Alpha. When I ported DCE Threads to AXP,
  I got to learn AXP Assembler - this was MUCH easier to port than DCE
  threads.  Of course, I found this little nasty:

 struct	 lwp_ctl {			/* LWP control structure */
        int	processcnt;		/* number of lightweight processes */
        char	*outersp;		/* outermost stack pointer */
        PROCESS	outerpid;		/* process carved by Initialize */
    	PROCESS	first, last;		/* ptrs to first and last pcbs */
==>     long	dsptchstack[800];	/* stack for dispatcher use only */
					/* jrd_at_bu.edu 02/10/1998: stack align*/
  }

This was previously:	
	char	dsptchstack[800];	/* stack for dispatcher use only */
Which is all wrong, because on an ALPHA this means that the stack is
not guaranteed to be longword aligned.

- I run the LWP tests:

jrd_at_italpha1$ ./test 5
