a84055b552 use the ALIGN macro to align the stack, rather than rounding up
by a (char *).  the former is safe, even on strange machines
(read: sparc).

772436479d new, improved, and rationally-implemented vfs_bio. no more serious
structural changes should happen, as it now does the right thing
w.r.t. buffer resizing and having lots of buffers vs. relatively
little buffer space.  Ports can now "do the standard thing", re:
nbuf and bufpages, which is make nbuf = bufpages by default.

e27f6e3ea0 patch from Christoph Badura <bad@flatlin.ka.sub.org> to fix credential
use by read-ahead blocks.  This fixes those weak NFS authentication
messages, and allows us to use BSDI NFS servers again...

1d0f22a29a convert to use the buffers which are (now) statically allocated at
startup in machdep.c...  buffers are now *never* allocated after boot.
currently, the limitation that says bufpages must cover nbuf*MAXBSIZE
still exists, but this is one step closer to removing that limitation.

9c32bc786a make allproc be volatile, and cast things accordingly.
suggested by torek, because CSRG had problems with reordering
of assignments to allproc leading to strange panics from kernels
compiled with gcc2...

de69711383 These changes are due to a mismatch with user functions prototyped as
func(short) and the fact the the kernel uses full ints.  This caused
problems on the pc532 port.  These fixes take the good 16 bits passed
by the user program and converts them into the correct form for the
kernel.

15359c9f59 enable loadable execution handlers. need to do something better re:
how much of the file to pass in the exec package, but i think the
solution to that will be to pass e.g. a disk block's worth, or whatever;
if exec handlers really need more, they've got the damned vnode.

fddf2c7605 ptrace_single_step() and ptrace_set_pc() should return errors if
necessary.  (Mainly because the SPARC can't easily single step, so
it should return EINVAL, and then ptrace() should return that to the
user.)

518f7c78d6 a program being exec'd *must* cause *some* exec commands to be invoked;
if it doesn't there's a problem in the kernel, because a program
with no exec commands run will have no address space except the stack,
and i don't think it's valid to have a "run from stack only" exec type,
so panic.  if need for that case comes up later, it can be changed...

54eb3b1f88 brought in fixed/renamed/matching MS-DOS FS code, from Jeff Polk
<polk@bsdi.com>.  His notes are as follows:
------------------------------------------------------------------------------

 July 22, 1993

 - Changed name of entire package from PCFS to MSDOSFS

 - Fixed bugs:
      root directory size in clusters instead of bytes
      growing directory didn't update in-core size
      link, symlink, mknod didn't free locked parent (deadlock)
      lookup returned real error on create and rename instead of EJUSTRETURN
      rename changed `.' entry in child instead of name entry in parent
      rename removed `.' entry in child instead of removing entry in
              parent when moving a directory from one dir to another
      createde() left new node locked when write of parent failed (deadlock)
      removede() decremented refcount even on error (rmdir's which failed
              due to write errors left in-core cache entries inconsistent)
      changed validation for filesystem to not check for the boot signature
              since some disks (e.g., mtools) aren't bootable
      directories are always show current time as modify time
              (needed for NFS export since DOS never updates dir mod times --
               ctime is true create time).

 - Added support for cookies changes to the readdir() vnode
      interface (#ifdef __bsdi__)

 - Punted on the whole problem of inode generation numbers.  This means
   that there's a chance of using a stale file handle to access a new
   file, but it doesn't appear to be the common case, and I don't see
   how to generate reasonable generation numbers without changing something
   on the disk (which is the way the SVR4 filesystem survival kit guys
   did it).  I don't think it would be very safe to change the on-disk
   format.

        Jeff Polk (polk@BSDI.COM)
