c8efb16966 Catch up to jmpbuf changes. Define offsets used from assmebly language
in another file so that it is easy to see what they are and keep them in
sync with the headers (grafted from the kernel generated assym.s).

86f466074c 1. Split fp.h into fp.h and fsr.h so that the latter can be included
in asm files.
2. Temporarily cause subnormal operands in floating point operations
   to be treated as zeros so that comlpetion of the operation does not
   need to be emulated.
3. Catch fp_exception_other and correctly skip over the unfinished
   instruction, but basically ignore them.  Emulating the instruction
   is not yet supported.
4. Zero td_retval[1] as well in syscall().

d5a7911f4a 1. Remove kdbframe. Bad idea.
2. Add a TF_DONE macro, which fiddles a trapframe to make the retry on
   return from traps act like a done (advance past the trapping
   instruction instead of re-executing).
3. Flush the windows before entering the debugger, since it is no
   longer done in the breakpoint trap vector.
4. Print a warning if trace <pid> is attempted, it is not yet implemented.
5. Print traps better and decode system calls in traces.

cb67f0018f 1. Convert the tstate saved in the pcb to a pstate and test for PSTATE_PEF
to determine if a process is using floating point. in order to avoid
   sign extending a 13 bit immediate.
2. We don't need to context switch cwp anymore, it is better to just
   fiddle the save tstate on return from traps.  See exception.s 1.10
   and 1.12.
3. Completely remove pcb_cwp.
4. Implement vmapbuf, vunmapbuf and vm_fault_quick.  Completely remove
   TODOs from vm_machdep.c (yay!).

4d5e57d87d 1. Implement ascopyto() and ascopyfrom() for copying to an alternate address
space from kernel space and from an alternate address space to kernel
   space.
2. Remove the unused and unprototyped physcopy() and physzero() and replace
   with the more versatile ascopy() and aszero(), inspired by the above.
   These can be used to copy and zero physical pages of memory without mapping
   them into kernel space first.
3. Use magic numbers for the offsets in the jmpbuf structure like other
   platforms.
4. Use SET.

117037c4bd 1. Fix a bug where the offsets of the alignment and mmu fault recorvery code
in the window trap vectors were mixed up.  All this did is cause unnecesary
   traps and look wierd in traces.  Superfluous traps happen a lot in normal
   operation, so we are rather good at recovering from them.
2. Store the arguments for a ktr trace in the right place.
3. Use a generic trap vector for breakpoints.  It should not be special.
4. Save the frame pointer in the trap frame for kernel traps if DDB is compiled
   in, otherwsie we don't save the out registers for kernel traps and stack
   traces can't go through nested traps.
5. Apply the same fix to the return from kernel mode trap code as for user
   mode traps.  Ensure that the window we're returning to is the same one
   that we restore to by fiddling the cwp in the saved tstate.  This requires
   that we transfer the values loaded from the trap frame into alternate
   globals before restore-ing, but doing so is not very expensive and not
   worth worrying about.  Not changing the saved cwp can result in the register
   values magically changing on return from traps if we happen to have slept
   and the windows don't work out exactly the same.  Fix the trace just before
   the retry to account for different register usage.
6. Use a SET macro for loading address constants rather than a variation of
   set and setx.  set only works for 32 bit constants, while setx works for
   64 bit constants as well, but produces bloated code when unnecessary.
   Gas always generates the canonical 2 register, 6 instruction form, even
   when it could be optimized; set uses 1 register and 2 instructions.  At
   the moment we assume that the kernel binary is below 4GB so set is
   always sufficient, but the macro allows it to be configured.  Note that
   this has nothing to do with 32 vs. 64 bit address space, it only applies
   to addresses of symbols which are known at compile/link time.

946708bbea Remove a sentence from the BUGS section that claims non page-aligned
offsets don't work. It should really be documented that the returned
pointer can be in the middle of a fully-valid page when the offset
is not page-aligned, but I couldn't come up with suitable wording.

bf58d635ba Fix a large number of -Wall, -Wformat and -W compiler warnings.
These were mainly missing casts or wrong format strings in printf
statements, but there were also missing includes, unused variables,
functions and arguments.

The choice of `long' vs `int' still seems almost random in a lot
of places though.

ca8b9ed373 Add two new accounts/groups for sendmail:
smmsp - sendmail 8.12 operates as a set-group-ID binary (instead of
set-user-ID).  This new user/group will be used for command line
submissions.  UID/GID 25 is suggested in the sendmail documentation and has
been adopted by other operating systems such as OpenBSD and Solaris 9.

mailnull - The default value for DefaultUser is now set to the uid and gid
of the first existing user mailnull, sendmail, or daemon that has a
non-zero uid.  If none of these exist, sendmail reverts back to the old
behavior of using uid 1 and gid 1.  Currently FreeBSD uses daemon for
DefaultUser but I would prefer not to use an account used by other
programs, hence the addition of mailnull.  UID/GID 26 has been chosen for
this user.

This was discussed on -arch on October 18-19, 2001.

binary size increase is 3,784 bytes (about 0.6%).

I don't drop the printf builtin while I'm here because some /etc/rc.*
scripts seem to use it before mounting /usr where printf(1) resides.

3cf64d0fbb Be very generous with timeouts for synchronize cache. We may wait a very long
time in the cases where it really sends the drive out to lunch, but it also
allows us to catch very wierd edge cases of strange drives that might take
a very long time (emulated disk drives over a network, e.g.).

b1e4abd246 Give struct socket structures a ref counting interface similar to
vnodes.  This will hopefully serve as a base from which we can
expand the MP code.  We currently do not attempt to obtain any
mutex or SX locks, but the door is open to add them when we nail
down exactly how that part of it is going to work.

6729cb8800 Start bringing i386/pmap.c into line with cleanups that were done to
alpha pmap.  In particular -
- pd_entry_t and pt_entry_t are now u_int32_t instead of a pointer.
  This is to enable cleaner PAE and x86-64 support down the track sor
  that we can change the pd_entry_t/pt_entry_t types to 64 bit entities.
- Terminate "unsigned *ptep, pte" with extreme prejudice and use the
  correct pt_entry_t/pd_entry_t types.
- Various other cosmetic changes to match cleanups elsewhere.
- This eliminates a boatload of casts.
- use VM_MAXUSER_ADDRESS in place of UPT_MIN_ADDRESS in a couple of places
  where we're testing user address space limits.  Assuming the page tables
  start directly after the end of user space is not a safe assumption.
There is still more to go.
