2963ff5c58 Add l_poll' to struct linesw' and provide an xxxpoll() entry point 
in each tty driver to indirect through it.

This allows tty line-disciplines to handle poll(2) system calls.

cf67ac7122 Per discussion w/ chuck and chuck, restructure the md page stuff 
to use a structure called "vm_page_md", and use __HAVE_VM_PAGE_MD
and __HAVE_PMAP_PHYSSEG.

2b27ac7a99 Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for 
each vm_page structure.  Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM.  These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.

This deprecates struct pmap_physseg.  As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.

Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now).  Changes to other pmap
modules will follow.

fe3c9ceaf7 * Move definitions of exact-width integer types from <machine/types.h> 
to <sys/types.h> and <sys/stdint.h>.
* Add a new C99 <stdint.h> header, which provides integer types of
  explicit width, related limits and integer constant macros.
* Extend <inttypes.h> to provide <stdint.h> definitions and format
  macros for printf() and scanf().
* Add C99 strtoimax() and strtoumax() functions.
* Use the latter within scanf().
* Add C99 %j, %t and %z printf()/scanf() conversions for
  intmax_t, pointer-type and size_t arguments.

d7e12660a3 Work around the problem that causes kern/12554. Basically, 
there are some pathological cases that cause pmap_page_protect()
to be called on a wired page to revoke all mappings.  We
need to skip mappings that are actually wired to prevent Bad
things from happening later.

THIS IS JUST A WORK-AROUND.  We need to prevent the pathological
behavior from happening in UVM to begin with.  But it's unclear
what the right solution is there, right now.

1c3a62e066 Sprinkle pmap_update() calls after calls to: 
- pmap_enter()
- pmap_remove()
- pmap_protect()
- pmap_kenter_pa()
- pmap_kremove()
as described in pmap(9).

These calls are relatively conservative.  It may be possible to
optimize these a little more.

anything, and the interface itself wasn't as flexible as
callers would have probably liked.

15f731ee94 pmap_update() should not be equated with "flush entire TLB", it is 
used to process deferred pmap operations.  Since these pmaps don't
defer anything, pmap_update() is a noop.

KERN_NO_SPACE			ENOMEM
KERN_INVALID_ARGUMENT		EINVAL
KERN_FAILURE			various, mostly turn into KASSERTs

KERN_NOT_RECEIVER		<unused>
KERN_NO_ACCESS			<unused>

51aeeceeaf Clean up TLB trap handling a little. 
- When printing a user trap, include p->p_comm in the message.
- In the TLB fault handler, don't just go charging along if
  the fault can't be handled.  If we get a fatal kernel TLB
  fault, we need to panic!  Or, if DDB is enabled, call the
  Debugger().

bba3f2423b add comment about $CPP 
From source:

# XXX following definition is absolutely incorrect.
# Our cpp is not /usr/libexec/cpp but /usr/bin/cpp.
# True solution is:
#	1) copy /usr/bin/cpp into /usr/local/bin/sh-*-*-cpp
#	2) Edit CPP in sh-*-*-cpp correctly
#		(e.g. "CPP=`$CC -print-prog-name=cpp`").
#	3) Edit STDINCDIR in sh-*-*-cpp correctly
#		(e.g. STDINCDIR=/usr/local/sh-unknown-netbsdcoff/include)

ef2315d256 Rewrite how mod/ref emulation is done. In particular, make 
modified attribute checking actually work.  Previously, a
page could be reported as modified even if it wasn't!  This
is very bad, and e.g. caused the VM system to attempt to
"clean" pages of read-only files.

Only lip-services is paid to referenced attribute emulation.
This could be improved.
