5cb1fce026 Fix cut-and-paste-o that Nate found. We were setting csc_route twice,
rather than setting it once and setting func_route when we can't route
PCI interrupts.

b196d1ce5c Consistently use 'queueing' instead of 'queuing'. Both spellings are
correct, but the former seems to be preferred.  This makes all of the
section-4 manual pages consistent in this respect.

39b7ac5a89 Remove description of an option that only applies to UNICOS < 7.0.
That define may still be present in the source, but I don't think
anyone has plans to try to use it.

1485129b09 Document that IFF_MULTICAST should be ORd with IFF_POINTOPOINT or

86b2fc4de5 TUNSIFINFO now expects IFF_MULTICAST to be OR'd with either IFF_POINTOPOINT
or IFF_BROADCAST.  If it's not, the IFF_MULTICAST is removed.

This is in line with how NetBSD & OpenBSD do it.

0b370908b2 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.

3516c025ff 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.

268bdb43f9 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.

76dcbd6f9f 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).

5cb74fd363 Ok, third time is the charm. VM_INHERIT_XXX -> INHERIT_XX (use the same

dbad546ba7 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.

c45da89917 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.

d625c99d74 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.

7d1192a784 On today's kernels masking with ~KERNBASE is turning out to be less
