4dcf2bbbff Fix a LOR where ifconf() used copyout while holding a mutex. This LOR
was seen when configuring addresses on interfaces using ifconfig.  This
patch has been verified to work with over eight thousand addresses
assigned to an interface.

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
# compatibility macros.  They make finding bugs like this *MUCH*
# harder.

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
information until all of the pieces of the puzzle fell into place and
for testing an earlier patch.

2e2e32b201 Revert the last change..
Better to kill all other threads than to panic the system if 2 threads call
execve() at the same time. A better fix will be committed later.

Note that this only affects the case where the execve fails.

e19f6f27a7 Hopefully fix alpha and sparc64 builds: on these architectures,
libpthread is provided by src/lib/libc_r.

Also, removed lib/bind from _generic_libs, "lib" will suffice.
Also, removed redundant lib/bind dependency on lib/libpthread
(as lib/bind is not in the _prebuild_libs, it's not needed).

aa1cb3e183 Improve netsend timing logic in various ways:
- Centralize time comparison.
- Check clock resolution to make sure it has enough granularity to
  implement the desired wait interval.
- Keep track of how many times the timing loop has to spin waiting
  for the next send time; report statistics.
- Add commented out warning about deadlines being missed when
  spinning.
- Improve statistics reporting generally to provide a more useful
  summary of sender condition after a run.

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.

There is no need to skip providers with 0 sectorsize in taste routine,
it is now forced by GEOM.
Actually, it can even cause some problems, because GEOM requires sectorsize
to be greater than 0 on first access, not on provider creation, so we can
skip valid providers by doing this check in taste method.

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.
