6fdf763cef Like on i386, use the definition of struct bios_smap from machine/pc/bios.h
again.

2169193596 Converge towards i386. I originally resisted creating <machine/pc/bios.h>
because it was mostly irrelevant - except for the silly BIOS_PADDRTOVADDR
etc macros.  Along the way of working around this, I missed a few things.

* Make syscons properly inherit the bios capslock/shiftlock/etc state like
  i386 does.  Note that we cannot inherit the bios key repeat rate because
  that requires a bios call (which is impossible for us).
* Give syscons the ability to beep on amd64.  Oops.

While here, make bios.c compile and add it to files.amd64.

c3277f936c Severely strip down the repocopied i386/bios.c and bios.h files. It turns
out that bios_sigsearch() etc is useful for finding tables in roms.

- td_upcall is (k + j)
- td_sticks is (k) rather than the earlier (j) note.
- td_uuticks and td_usticks are both (k).
- td_intrval is (j)
- Neither kg_nextupcall or kg_upquantum seem to be locked and that seems

Users should move to the new geom_vinum implementation instead.

The refcount logic which is being added to devices to enable safe module

of the (old)-vinum code to comply with the new semantics.

The actual source files will not be removed until I have coordinated with

9c3ae2ef4b Add a temporary workaround to the panic on boot with hub attached and
panic on hub detach bugs that have been reported.  This work around
detaches the device before deleting it.  This changes the detach order
from in-order to pre-order.  This avoids uhub's deleting the children
after its subdevs has been deleted.

This is only a workaround.  This leads to a strange condition in the
device tree where attached devices are children of detached ones.  I
really don't know what that's supposed to mean, but does violate my
sense of POLA.  Fortunately, the violation is short lived, which is
why I'm going ahead and committing the work around.

# We really need to consider life w/o the multiple nested layers of

a971139680 Correct a long-standing error in _pmap_unwire_pte_hold() affecting
multiprocessors.  Specifically, the error is conditioning the call to
pmap_invalidate_page() on whether the pmap is active on the current CPU.
This call must be unconditional.  Regardless of whether the pmap is active
on the CPU performing _pmap_unwire_pte_hold(), it could be active on another
CPU.  For example, a call to pmap_remove_all() by the page daemon could
result in a call to _pmap_unwire_pte_hold() with the pmap inactive on the
current CPU and active on another CPU.  In such circumstances, failing to
call pmap_invalidate_page() results in a stale TLB entry on the other CPU
that still maps the now deallocated page table page.  What happens next is
typically a mysterious panic in pmap_enter() by the other CPU, either
"pmap_enter: attempted pmap_enter on 4MB page" or "pmap_enter: pte vanished,
va: 0x%lx".  Both occur because the former page table page has been recycled
and allocated to a new purpose.  Consequently, it no longer contains zeroes.

See also Peter's i386/i386/pmap.c revision 1.448 and the related e-mail
thread last year.

Many thanks to the engineers at Sandvine for providing clear and concise

76764432e4 - Add support for "paging" in stack trace output. That is, when you do
a stack trace from ddb, the output will pause with a '--More--' prompt
  every 18 lines.  If you hit Enter, it will print another line and prompt
  again.  If you hit space it will output another page and then prompt.
  If you hit 'q' or 'x' it will abort the rest of the stack trace.
- Fix the sparc64 userland stack trace to honor the total count of lines
  to print.  This is useful if your trace happens to walk back onto
  0xdeadc0de and gets stuck in an endless loop.

083ba097fd das@ has a ACPI bios that lists 0x3f0-0x3f1, 0x3f2-0x3f3, 0x3f4-0x3f5
and 0x3f7.  fdc_isa_alloc_resource() didn't work right in this case
(it accessed FDOUT correctly due to an overflow of the first resource.
It accesed FDSTS and FDDATA incorrectly via the second resource (which
wound up accessing FDOUT and the tape register at 0x3f3) and badly for
the CTL register (at location 0x3f4).  This is a minimal fix that just
'eats' the first one if it covers two locations and has an offset of
0.  This confusion lead the floppy driver to think there'd been a disk
change, which uncovered a deadlock in the floppy/geom code which lead
to a panic.  These changes fix that by fixing the underlying resource
problem, but doesn't address the potential deadlock issue that might
still be there.

This is a minimal fix so it can more safely be merged into 5 w/o risk
for known working configurations (hence the use of the ugly goto,
which reduces case 8 to case 6 w/o affecting cases 1-7).  A more
invasive fix that will handle more ACPI resource list diversity is in
the pipeline that should kill these issues once and for all, while
staying within the resources that we allocate.

6b1c98e2be - Some of the upper bits of the time related (seconds, minutes, etc.)
registers are control bits or depending on the model contain additional
  time bits with a different meaning than the lower ones. In order to
  only read the desired time bits and not change the upper bits on write
  use appropriate masks in the gettime and settime function respectively.
  Due to the polarity of the stop oscillator bit and the fact that the
  century bits aren't used on sparc64 not masking them didn't cause
  problems so far.
- Fix two off-by-one errors in the handling of the day of week. The
  genclock code represents the dow as 0 - 6 with 0 being Sunday but the
  mk48txx use 1 - 7 with 1 being Sunday. In the settime function when
  writing the dow to the clock the range wasn't adjusted accordingly but
  the clock apparently played along nicely otherwise the second bug in
  the gettime function which mapped 1 - 7 to 0 - 6 but with 0 meaning
  Saturday would have been triggered. Fixing these makes the date being
  stored in the same format Sun/Solaris uses and cures the "Invalid time
  in real time clock. Check and reset the date immediately!" when the
  date was set under Solaris prior to booting FreeBSD/sparc64. [1]
  Looking at other clock drivers/code e.g. FreeBSD/alpha the former "bug",
  i.e. storing the dow as 0 - 6 even when the clock uses 1 - 7, seems to
  be common but might be on purpose for compatibility when multi-booting
  with other OS which do the same. So it might make sense to add a flag
  to handle the dow off-by-one for use of this driver on platforms other
  than sparc64.
- Check the state of the battery on mk48txx that support this in the
  attach function.
- Add a note that use of the century bit should be implemented but isn't
  required at the moment because it isn't used on sparc64.

de6c3db01f Simplify the reference counting of page table pages. Specifically, use
the page table page's wired count rather than its hold count to contain
the reference count.  My rationale for this change is based on several
factors:

1. The machine-independent and pmap layers used the same hold count field
   in subtly different ways.  The machine-independent layer uses the hold
   count to implement a form of ephemeral wiring that is used by pipes,
   physio, etc.  In other words, subsystems where we wish to temporarily
   block a page from being swapped out while it is mapped into the kernel's
   address space.  Such pages are never removed from the page queues.
   Instead, the page daemon recognizes a non-zero hold count to mean "hands
   off this page."  In contrast, page table pages are never in the page
   queues; they are wired from birth to death.  The hold count was being
   used as a kind of reference count, specifically, the number of valid
   page table entries within the page.  Not surprisingly, these two
   different uses imply different synchronization rules: in the machine-
   independent layer access to the hold count requires the page queues
   lock; whereas in the pmap layer the pmap lock is required.  Thus,
   continued use by the pmap layer of vm_page_unhold(), which asserts that
   the page queues lock is held, made no sense.

2. _pmap_unwire_pte_hold() was too forgiving in its handling of the wired
   count.  An unexpected wired count on a page table page was ignored and
   the underlying page leaked.

3. In a word, microoptimization.  Using the wired count exclusively, rather
   than a combination of the wired and hold counts, makes the code slightly
   smaller and faster.

d705e025d0 The getpages VOP was a good stab at getting scatter/gather I/O without
too much kernel copying, but it is not the right way to do it, and it is
in the way for straightening out the buffer cache.

The right way is to pass the VM page array down through the struct
bio to the disk device driver and DMA directly in to/out off the
physical memory.  Once the VM/buf thing is sorted out it is next on
the list.

Retire most of vnode method. ffs_getpages().  It is not clear if what is
left shouldn't be in the default implementation which we now fall back to.

ca9b2364c3 A long, long time ago in a CVS branch far away (specifically, HEAD prior
to 4.0 and RELENG_3), the BTX mini-kernel used paging rather than flat
mode and clients were limited to a virtual address space of 16 megabytes.
Because of this limitation, boot2 silently masked all physical addresses
in any binaries it loaded so that they were always loaded into the first
16 Meg.  Since BTX no longer has this limitation (and hasn't for a long
time), remove the masking from boot2.  This allows boot2 to load kernels
larger than about 12 to 14 meg (12 for non-PAE, 14 for PAE).

27df52f999 The long dead hand of the past has pushed forward useless bits in this
driver.  Trim its fingernails by removing some useless bits before
fixing the 'thread not terminated on detach' problem.

o dmacnt is no longer used now that we allocate at attach time.  Remove
  it from struct fdc_data.
o ISPNP was only ever set, but never tested.  It used to be used for the
  allocation routines to change how it allocated resources.  Since that's
  no longer necessary, retire the flag.
o ISPCMICA was only ever tested, but never set.  GC it.  This removes
  a special case in determining the drive type.  The drive type is
  now set in fdc_pcmcia.c, so the hack isn't needed anymore.  Sadly,
  this isn't tested with a Y-E Data pcmcia floppy drive because there
  are a number of other issues that preclude it from working.
o Fix ifdef for reading from the rtc.  I'm of the opinion that this ifdef
  should be moved into fdc_isa.c, but not today as ideally there'd be
  other fixes to the probing of children.  So now we just read it on
  i386 ! pc98 (there's no #define for MACHINE_ARCH, just MACHINE, hence
  this slightly inelegant kludge) and amd64.  The PC98 exclusion likely
  isn't meaningful since pc98 uses a different driver, but will be when
  merging of the pc98 floppy code into this driver is complete (this is the
  other reason I think this block of code belongs outside fdc.c).

All of these changes are safe to MT5.

dc961de0b4 Commit patch to supress spurious link change events. Apparently, with
copper NICs, a link change event is posted whenever MII autopolling is
toggled off and on, which happens whenever someone calls
bge_miibus_readreg() or bge_miibus_writereg() to access the PHY
registers. This means anytime someone called the SIOCGIFMEDIA ioctl
on a bge interface, the link would reset. Even a simple "ifconfig bge0"
would do it, though other apps like dhclient or the PPPoE daemon could
trigger it as well. An obvious symptom of this problem is lots of
"bgeX: gigabit link up" messages appearing on the console for no
apparent reason.

Through experimentation, I determined that when a real link change
event occurs, the BGE_MIMODE_AUTOPOLL in the BGE_MI_MODE register
is always set, so now if we have a copper NIC and an link change
event occurs and the BGE_MIMODE_AUTOPOLL bit is clear, we ignore
the event.

Note that this does not apply to the original BCM5700 chip since we
use a different method for sensing link changes with that chip (the
status block method was broken), nor to fiber optic NICs since they
don't use the GMII PHY access registers.

This make "_NEC" devices appear as "NEC" which is more corrent.
The reason is tha NEC originally screwed up on the byteorder in the
model string, so now that they have realized that they prefixed the '_'
so that not every ATA driver on the planet would call them "EN C" :)

7964bd0c70 Reserve the DMA memory at attach time, rather than at use. While
reserving it at use time is more miserly, low memory (< 16MB)
evaporates quickly on many systems, so there may not be any suitable
buffers available.  This specifically doesn't use the newer, fancier
isa_dma_init to ease merging to 5.

e098266191 Remove the last two global variables that are used to store packet state while
it travels through the IP stack.  This wasn't much of a problem because IP
source routing is disabled by default but when enabled together with SMP and
preemption it would have very likely cross-corrupted the IP options in transit.

The IP source route options of a packet are now stored in a mtag instead of the
global variable.

ad6c618bc7 Make two major changes to this code to address some stability/corruption
problems:

1) Add locking for SMP, code provided by Alan Cox
2) While testing Alan's patches, I observed serious problems with
   the jumbo buffer allocation code (machine crashed twice), so I gutted
   it and rewrote the receive handler to use multiple chained descriptors.
   Each RX descriptor gets a single 2K cluster, and the chip will fill in
   as many as it needs to hold the complete packet.

User reports that this corrects the data corruption issues previously
observed and discussed on -current.

Note that this driver still needs to be hit with the busdma stick.
I intend to inflict said beating in the near future.

031102cc7b Use an atomic op to update the pte in pmap_protect(). This is to prevent
the loss of a page modified (PG_M) bit in a race between processors.

Quoting Tor:
	One scenario where the old code could cause a lost PG_M bit is a
	multithreaded linux program (or FreeBSD program using the
	linuxthreads port) where one thread was starting a subprocess.
	The thread doing fork() would call vmspace_fork(), which would then
	call vm_map_copy_entry() which would call pmap_protect() on an area
	possibly accessed by other threads.

Additionally, make the clearing of PG_M by pmap_protect() unconditional if
write permission is removed.  Previously, PG_M could persist on a read-only
unmanaged page.  That seems inconsistent and confusing.

holds sndstat_lock across a call to uiomove(), which is not legal
to do with a  mutex because of the possibility that the data transfer
could sleep because of a page fault.  It is not possible to just
unlock the mutex for the uiomove() call without introducing another
locking mechanism to prevent the body of sndstat_read() from being
