Change the vm_map's "entries_pageable" member to a r/o flags member, which
...
has PAGEABLE and INTRSAFE flags. PAGEABLE now really means "pageable",
not "allocate vm_map_entry's from non-static pool", so update all map
creations to reflect that. INTRSAFE maps are maps that are used in
interrupt context (e.g. kmem_map, mb_map), and thus use the static
map entry pool (XXX as does kernel_map, for now). This will eventually
change now these maps are locked, as well.

bus_dmamem_map() maps DMA safe memory, which is usually one or more
...
managed pages, into KVA space. Since the pages are managed, we should
use pmap_enter(), not pmap_kenter_pa().
Also, when entering the mappings, enter with an access_type of
VM_PROT_READ | VM_PROT_WRITE. We do this for a couple of reasons:
(1) On systems that have H/W mod/ref attributes, the hardware
may not be able to track mod/ref done by a bus master.
(2) On systems that have to do mod/ref emulation, this prevents
a mod/ref page fault from potentially happening while in an
interrupt context, which can be problematic.
This latter change is fairly important if we ever want to be able to
transfer DMA-safe memory pages to anonymous memory objects; we will need
to know that the pages are modified, or else data could be lost!
Note that while the pages are unowned (i.e. "just DMA-safe memory pages"),
they won't consume any swap resources, as the mappings are wired, and
the pages aren't on the active or inactive queues.

Take advantage of the new `access_type' for pmap_enter(), and always do R/M
...
emulation of managed pages. This required the following `interesting' changes:
* File system buffers must be entered with an access type of
VM_PROT_READ|VM_PROT_WRITE, so that the pages will be accessible immediately.
Otherwise we would have to teach pagemove() to update the R/M information.
Since they're never eligible for paging, the latter is overkill.
* We must insure that pages allocated before the pmap is completely set up
(that is, pages allocated early by the VM system) are not eligible for R/M
emulation, since the memory needed for this isn't available. We do this by
allocating the pmap's internal memory with uvm_pageboot_alloc(). This also
fixes an absolutely horrible hack where the pmap only worked because page 0
happened to be mapped.
to be mapped.
Also:
* Push the wired page counting into the p->v list maintenance functions. This
avoids code duplication, and fixes some cases where we were confused about
which pages to do it with.
* Fix lots of problems associated with pmap_nightmare() (and rename it to
pmap_vac_me_harder()).
* Since the early pages are no longer considered `managed', just make
pmap_*_pv() panic if !pmap_initialized.

Make sure ISA interrupts have been setup prior to configuring devices.

This is not nice and a better solution is needed. Really this should be

some PCI interrupts may be routed via the ISA interrupt controller
and thus this needs setting up first.

Rework the way kernel include files are installed. In the new method,
...
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

Use a separate variable to indicate whether the fault is from USR mode
...
or not rather than orring in a USER bit into the fault code variable.
This simplifies the fault switch statement and some of the addition
checks that are made of the fault code.
Move the printing of data abort information out into a separate function
rather then duplicating a lot of similar printf() statements.
Removed the fault_code variables from the prefetch abort handler as it
is not actually used for anything.

Major overhaul of pagetable handing.
...
Page tables no longer occupy space in the processes vm_map. This
means that page tables can now be allocated from pmap_enter() when the
first entry is made in the page table rather than relying on taking
a section fault and faulting in a page table. This also lowers
the overheads in creating and deleting page tables and simplfies
cpu_fork().
A result of this change is that problems with mapping zero page and
an associated pagetable when execing from a shared vm_map disappear
fixing PR5178.
