5cdc9f7c0c First cut at getting the ISA routing working. If we can't route a PCI
interrupt for the CSC interrupt, then we revert to ISA.  If we didn't
have an interrupt set up with hw.pcic.irq, then do polling.

Also, don't complain about ignoring function 1 for any devices except
pcic devices.  This would normally only show up if someone set
hw.pcic.ignore_function_1=1.

MFC: as soon as I can test it on some troublesome laptops.

e0dbc46fb0 Implement idle zeroing of pages. I've been tinkering with this
on and off since John Dyson left his work-in-progress.

It is off by default for now.  sysctl vm.zeroidle_enable=1 to turn it on.

There are some hacks here to deal with the present lack of preemption - we
yield after doing a small number of pages since we wont preempt otherwise.

This is basically Matt's algorithm [with hysteresis] with an idle process
to call it in a similar way it used to be called from the idle loop.

I cleaned up the includes a fair bit here too.

70aca15c21 Optionize UPAGES for the i386. As part of this I split some of the low
level implementation stuff out of machine/globaldata.h to avoid exposing
UPAGES to lots more places.  The end result is that we can double
the kernel stack size with 'options UPAGES=4' etc.

This is mainly being done for the benefit of a MFC to RELENG_4 at some
point.  -current doesn't really need this so much since each interrupt
runs on its own kstack.

bogus additional write to WXREG_IMASK that enabled *all* interrupt causes

12d4e47ee8 Force a commit on kern_mutex.c to explain reason for last commit but while
I'm at it also add a comment in mtx_validate() explaining the purpose
of the last change.

Basically, this fixes booting kernels compiled with MUTEX_DEBUG. What used
to happen is before we setidt from init386() [still using BTX idt], we
called mtx_init() on several mutex locks, notably Giant and some others.
This is a problem for MUTEX_DEBUG because it enables mtx_validate() which
calls kernacc(), some of which in turn requires Giant.
Fix by calling kernacc() from mtx_validate() only if (!cold).

c6694b94db Rename the DIAGNOSTICS section to RETURN VALUES and describe the
return values a little more.  Specifically, mention that a return
of 0 from NgRecvData() and NgRecvMsg() means the socket has been
closed.

082a1e71f3 Update the mmap.2 and minherit.2 manual pages. Add a short explanation and
referal from mmap to minherit for MAP_INHERIT.  Fully document the
minherit.2 manual page (because frankly, my dear, however you think it
currently works is almost certainly wrong!).  I may soon re-implement
MAP_COPY because I believe we can support it properly now, but I will have
to call it something else and that is for a later time.

7f91d3a773 Remove MAP_NOEXTEND. It came from 4.4-lite and not only was never
implemented, but mmap()'s default behavior is *already* to not extend
files.  Only write() or ftruncate() can extend a file.

7dc16b8484 Explain what we're doing in pcic_pci_shutdown a little better. Try to
explain the subtle side effects that are going to happen and why we go
ahead and ack the interrupt source.  This stuff is tricky to get
right.

Also, emperical tests have shown that doing a shutdown in attach to be
ineffectual, so remove it from there.  Analysis of the code paths
shows that nearly identical writes to these registers happen in later
parts of the code.  The hanging problem on thinkpads when we change
the interrupt routing type is something else.

c05ab921af On today's kernels masking with ~KERNBASE is turning out to be less
than useful.  It still hits at least 8 digits. Adjust for reality.

This is still not satisfactory for the alpha if you add "-O paddr".

7ebebd6970 Move code to shutdown the pcic_pci_shutdown. Call it on system
shutdown and also before we get going with the device initialization.
This may fix the hangs some people are seeing on warmboot.  It appears
that some machines will reset the cardbus bridge on boot, while others
don't.  So we turn off the card, and ack the interrupts (which likely
is a nop in the shutdown case since we're still fielding interrupts).
This should turn off the interrupts.

Since I don't have hardware that hangs on reboot, I'm committing this
without testing that aspect of the patch (it causes no harm on my
Dell).

3e8c6264e6 Two fixes. First, put into place a more generic chipset specific
initialization structure.  Warn the user for those chipsets that
aren't yet customized that they might not work.  Second, try to power
off the slot on attach and ack the interrupts.  I don't know, but this
might solve the hangs that people will see on Thinkpads if they set
hw.pcic.init_routing=1.
