32585dd617 o In vm_object_madvise() and vm_object_page_remove() replace
vm_page_sleep_busy() with vm_page_sleep_if_busy().  At the same time,
   increase the scope of the page queues lock.  (This should significantly
   reduce the locking overhead in vm_object_page_remove().)
 o Apply some style fixes.

9eb881f804 - Optimize wakeup() and its friends; if a thread waken up is being
swapped in, we do not have to ask for the scheduler thread to do
  that.

- Assert that a process is not swapped out in runq functions and
  swapout().

- Introduce thread_safetoswapout() for readability.

- In swapout_procs(), perform a test that may block (check of a
  thread working on its vm map) first.  This lets us call swapout()
  with the sched_lock held, providing a better atomicity.

61f869600d Add definitions for statistical and high-resolution profiling. The calling
conventions for _mcount and __cyg_profile_func_enter are different, so
statistical profiling kernels build and link but don't actually work.
IWBNI one could tell gcc to only generate calls to the former.

Define uintfptr_t properly for userland, but not for the kernel (I hope).

1d7b9ed2e6 Create a new thread state to describe threads that would be ready to run
except for the fact tha they are presently swapped out. Also add a process
flag to indicate that the process has started the struggle to swap
back in. This will be  needed for the case where multiple threads
start the swapin action top a collision. Also add code to stop
a process fropm being swapped out if one of the threads in this
process is actually off running on another CPU.. that might hurt...

49545b3891 Create a new header <machine/_stdint.h> for storing MD parts of
<stdint.h>.  Previously, parts were defined in <machine/ansi.h> and
<machine/limits.h>.  This resulted in two problems:
  (1) Defining macros in <machine/ansi.h> gets in the way of that
      header only defining types.
  (2) Defining C99 limits in <machine/limits.h> adds pollution to
      <limits.h>.

08c0f3d917 If we are in hostap mode, do not go into promisc mode. This causes
problems with the firmware and will result in a) poor performance and
b) the inability to associate certain types of cards (most notibly

Idea obtained from OpenBSD, but I implemented it by clearing the
IFF_PROMISC flag rather than the refusing to honor it downstream.

e2102ae475 Revert rev 1.131.
1.131 is slightly broken, and I would commit the fix to that here, but it
has been reported that any deviation from the original code is causing
problems with some 82557 chips, causing them to lock hard.

Until those issues have been figured out, going back to the original
code is the best plan.

9e74cba35a Make a temporary copy of the output data in the generic sysctl handlers
so that the data is less likely to be inconsistent if SYSCTL_OUT() blocks.
If the data is large, wire the output buffer instead.

This is somewhat less than optimal, since the handler could skip the copy
if it knew that the data was static.

If the data is dynamic, we are still not guaranteed to get a consistent
copy since another processor could change the data while the copy is in
progress because the data is not locked.  This problem could be solved if
the generic handlers had the ability to grab the proper lock before the
copy and release it afterwards.

This may duplicate work done in other sysctl handlers in the kernel which
also copy the data, possibly while a lock is held, before calling they call
a generic handler to output the data.  These handlers should probably call
SYSCTL_OUT() directly.

5c38b6dbce Wire the sysctl output buffer before grabbing any locks to prevent
SYSCTL_OUT() from blocking while locks are held.  This should
only be done when it would be inconvenient to make a temporary copy of
the data and defer calling SYSCTL_OUT() until after the locks are
released.

af13e3abb9 Unimplement panic(8) by making sure that we don't recurse into a
ruleset.  If we do, that means there's a ruleset loop (10 includes 20
include 30 includes 10), which will quickly cause a double fault due
to stack overflow (since "include" is implemented by recursion).
(Previously, we only checked that X didn't include X.)

30bbe52432 Implement a direct mapped address region, like alpha and ia64. This
basically maps all of physical memory 1:1 to a range of virtual addresses
outside of normal kva.  The advantage of doing this instead of accessing
phsyical addresses directly is that memory accesses will go through the
data cache, and will participate in the normal cache coherency algorithm
for invalidating lines in our own and in other cpus' data caches.  So
we don't have to flush the cache manually or send IPIs to do so on other
cpus.  Also, since the mappings never change, we don't have to flush them
from the tlb manually.
This makes pmap_copy_page and pmap_zero_page MP safe, allowing the idle
zero proc to run outside of giant.

586261a30f Reserve VCACHEDLABEL vnode flag for use by the TrustedBSD MAC
implementation.  This flag will indicate that the security label
in the vnode is currently valid, and therefore doesn't need to
be refreshed before an access control decision can be made.  Most
file systems (or stdvops) will set this flag after they load the
MAC label from disk the first time to prevent redundant disk I/O;
some file synthetic file systems (procfs, for example) may not.

e277218592 Frequency default should be '25' for 25MHz, not 25000000.
Through the PITA of endiannness, clock has to be MHz freq << 8.

Don't trust NVRAM on SBus cards.

Set a default initiator ID sensibly.

SBus/ISP now working, what with the change to sbus.c earlier today.

43722a425a Don't test against default_iid being zero as a test for whether we
set something- iid 0 is valid.

f4f5cb1ffb o Remove a vm_page_deactivate() that is immediately followed by a
vm_page_rename() from vm_object_backing_scan().  vm_page_rename()
   also performs vm_page_deactivate() on pages in the cache queues,
   making the removed vm_page_deactivate() redundant.

72429e49f5 Make sure that if are in fact using 'full SMP', make the interrupt
flags include INTR_MPSAFE. Put the flags in a common place so that
both isp_sbus && isp_pci DTRT.

In isp_mbxdma setup, drop any locks prior to calling things like
bus_dmatag_create. This gets rid of these obnoxious WITNESS messages
about 'sleeping with locks held' blah blah blah blah blah.
