71426610ff Distinguish fifos from sockets in the S_IS* macros. This is possible now
that nameless pipes are not implemented as sockets.

Don't include <sys/time.h> if KERNEL is defined.  It should already have
been included by including <sys/param.h>.  Fixed a nearby typo.

4e7506495b Include <sys/buf.h> instead of <sys/vnode.h>. kern_sysctl.c no
longer has anything to do with vnodes and never had anything to do
with buffers, but it needs the definitions of B_READ and B_WRITE
for use with the bogus useracc() interface and was getting them
bogusly due to excessive cleanups in rev.1.49.

8d94b804a1 Fix an infinite loop caused by calling ahc_run_done queue while the

for the controller driver to "freeze" its queue during recovery operations
which would make all of this gymnastics unnecessary.

e2d8771131 Lower the spl() of the new process from splhigh() right away, since
nothing else will lower it until either much later, or never(?) for
kernel processes.

This basically re-fixes what Bruce fixed in rev 1.29 of kern_fork.c,
which was broken again now the child does not execute back up the fork()
calling tree.

a0c3795f19 Use UPAGES_HOLE instead of UPAGES in case it's changed some time.
Rename the PT* index KSTK* #defines to UMAX*, since we don't have a kernel
stack there any more..

These are used to calculate VM_MAXUSER_ADDRESS and USRSTACK, and really
do not want to be changed with UPAGES since BSD/OS 2.x binary compatability
depends on it.

a2a1c95c10 The biggie: Get rid of the UPAGES from the top of the per-process address
space. (!)

Have each process use the kernel stack and pcb in the kvm space.  Since
the stacks are at a different address, we cannot copy the stack at fork()
and allow the child to return up through the function call tree to return
to user mode - create a new execution context and have the new process
begin executing from cpu_switch() and go to user mode directly.
In theory this should speed up fork a bit.

Context switch the tss_esp0 pointer in the common tss.  This is a lot
simpler since than swithching the gdt[GPROC0_SEL].sd.sd_base pointer
to each process's tss since the esp0 pointer is a 32 bit pointer, and the
sd_base setting is split into three different bit sections at non-aligned
boundaries and requires a lot of twiddling to reset.

The 8K of memory at the top of the process space is now empty, and unmapped
(and unmappable, it's higher than VM_MAXUSER_ADDRESS).

Simplity the pmap code to manage process contexts, we no longer have to
double map the UPAGES, this simplifies and should measuably speed up fork().

The following parts came from John Dyson:

Set PG_G on the UPAGES that are now in kernel context, and invalidate
them when swapping them out.

Move the upages object (upobj) from the vmspace to the proc structure.

Now that the UPAGES (pcb and kernel stack) are out of user space, make
rfork(..RFMEM..) do what was intended by sharing the vmspace
entirely via reference counting rather than simply inheriting the mappings.

271b264e4c No longer use an i386tss as the basis of our pcb - it wasn't particularly
convenient and makes life difficult for my next commit.  We still need
an i386tss to point to for the tss slot in the gdt, so we use a common
tss shared between all processes.

Note that this is going to break debugging until this series of commits
is finished.  core dumps will change again too. :-(  we really need
a more modern core dump format that doesn't depend on the pcb/upages.

This change makes VM86 mode harder, but the following commits will remove
a lot of constraints for the VM86 system, including the possibility of
extending the pcb for an IO port map etc.

2100d64585 Commit a typo fix that's been sitting in my tree for ages, quite forgotten.
The typo was detected once apon a time with the -Wunused compile option.
The result was that a block of code for implementing
madvise(.. MADV_SEQUENTIAL..) behavior was "dead" and unused, probably
negating the effect of activating the option.

0ddf9be1f0 Make MOD_* macros almost consistent:
Use the name argument almost the same in all LKM types.  Maintain
the current behavior for the external (e.g., modstat) name for DEV,
EXEC, and MISC types being #name ## "_mod" and SYCALL and VFS only
#name.  This is a candidate for change and I vote just the name without
the "_mod".

Change the DISPATCH macro to MOD_DISPATCH for consistency with the
other macros.

Add an LKM_ANON #define to eliminate the magic -1 and associated
signed/unsigned warnings.

Add MOD_PRIVATE to support wcd.c's poking around in the lkm structure.

Change source in tree to use the new interface.

a04c970a7a Fix the gdb executable modify problem. Thanks to the detective work
by Alan Cox <alc@cs.rice.edu>, and his description of the problem.

The bug was primarily in procfs_mem, but the mistake likely happened
due to the lack of vm system support for the operation.  I added
better support for selective marking of page dirty flags so that
vm_map_pageable(wiring) will not cause this problem again.

The code in procfs_mem is now less bogus (but maybe still a little
so.)

1961f6e884 Instead of testing for both SELDI and SELDO in SSTAT0 in the poll for work
loop, test for them separately.  The bug report from David Malone showed that
even though we had been reselected (SELDI was true), we sat in the poll for
work loop until the selection timeout timer expired.  It may be that the
SSTAT0 register doesn't like to have more than one bit tested at a time.
I've seen stranger things than this on these parts.

844b7c2d86 Fix a bug in the selection timeout handler that was introduced when the
selection loop was merged with the poll_for_work loop.  We cannot assume
that the SCB for the selection timeout is the current SCB.  Instead we
must look at the SCB at the head of the waiting for selection list.

This fixes part of a problem reported by David Malone, but does not explain
why he was getting selection timeouts in the first place.
