806453645a Two changes to vm_fault_additional_pages():
1. Rewrite the backward scan.  Specifically, reverse the order in which
   pages are allocated so that upon failure it is never necessary to
   free pages that were just allocated.  Moreover, any allocated pages
   can be put to use.  This makes the backward scan behave just like the
   forward scan.

2. Eliminate an explicit, unsynchronized check for low memory before
   calling vm_page_alloc().  It serves no useful purpose.  It is, in
   effect, optimizing the uncommon case at the expense of the common
   case.

53dcfbd18b Add legacy interrupt handler which would be more appropriate for
interrupt that is shared with other devices(e.g. USB) in system and
provide a new tunable "hw.msk.legacy_intr" to activate the legacy
interrupt handler. Setting the tunable automatically disables MSI
for msk(4). Previously msk(4) used adoptive polling with taskqueue(9)
as all msk(4) hardwares I know supports MSI. However, there are cases
that MSI couldn't be used on some hardwares due to bugs in MSI
implementatins.

08af97b790 Attempt to improve feature parity between UDPv4 and UDPv6 by merging
UDPv4 features to UDPv6:

- Add MAC checks on delivery and MAC labeling on transmit.
- Check for (and reject) datagrams with destination port 0.
- For multicast delivery, check the source port only if the socket being
  considered as a destination has been connected.
- Implement UDP blackholing based on net.inet.udp.blackhole.
- Add a new ICMPv6 unreachable reply rate limiting category for failed
  delivery attempts and implement rate limiting for UDPv6 (submitted by
  bz).

 - Enable stealing load from the idle thread only when the remote processor
   has more than two transferable tasks.  Setting this to one further

 - Remove the bogus pick_zero option.  I had not intended to commit this.
 - Entirely disallow migration for threads with SRQ_YIELDING set.  This
   balances out the extra migration allowed for with the load balancers.
   It also makes pick_pri perform better as I had anticipated.

08c9a16c4f - When newtd is specified to sched_switch() it was not being initialized
properly.  We have to temporarily unlock the TDQ lock so we can lock
   the thread and add it to the run queue.  This is used only for KSE.
 - When we add a thread from the tdq_move() via sched_balance() we need to
   ipi the target if it's sitting in the idle thread or it'll never run.

f9ae02802f - Enable static building of mxge(4) and its firmware.
- Add custom .c wrappers for the firmware, rather than the standard
  firmware(9) generated firmware objects to work around toolchain
  problems on ia64 involving linking objects produced by
  ld -b -binary into the kernel.

- Move from using Myricom's ".dat" firmware blobs to using Myricom's
  zlib compressed ".h" firmware header files.  This is done to
  facilitate the custom wrappers, and saves a fair amount of wired
  memory in the case where the firmware is built in, or preloaded.

- Fix two compile issues in mxge which only appear on non-i386/amd64.

ae7a6b38d5 ULE 3.0: Fine grain scheduler locking and affinity improvements. This has
been in development for over 6 months as SCHED_SMP.
 - Implement one spin lock per thread-queue.  Threads assigned to a
   run-queue point to this lock via td_lock.
 - Improve the facility for assigning threads to CPUs now that sched_lock
   contention no longer dominates scheduling decisions on larger SMP
   machines.
 - Re-write idle time stealing in an attempt to make it less damaging to
   general performance.  This is still disabled by default. See
   kern.sched.steal_idle.
 - Call the long-term load balancer from a callout rather than sched_clock()
   so there are no locks held.  This is disabled by default.  See
   kern.sched.balance.
 - Parameterize many scheduling decisions via sysctls.  Try to document
   these via sysctl descriptions.
 - General structural and naming cleanups.
 - Document each function with comments.

feda1a4372 Restore netstat -M functionality for most statistics on core dumps. In
general, when support was added to netstat for fetching data using sysctl,
no provision was left for fetching equivalent data from a core dump, and
in fact, netstat would _always_ fetch data from the live kernel using
sysctl even when -M was specified resulting in the user believing they
were getting data from coredumps when they actually weren't.  Some specific
changes:
- Add a global 'live' variable that is true if netstat is running against
  the live kernel and false if -M has been specified.
- Stop abusing the sysctl flag in the protocol tables to hold the protocol
  number.  Instead, the protocol is now its own field in the tables, and
  it is passed as a separate parameter to the PCB and stat routines rather
  than overloading the KVM offset parameter.
- Don't run PCB or stats functions who don't have a namelist offset if we
  are being run against a crash dump (!live).
- For the inet and unix PCB routines, we generate the same buffer from KVM
  that the sysctl usually generates complete with the header and trailer.
- Don't run bpf stats for !live (before it would just silently always run
  live).
- kread() no longer trashes memory when opening the buffer if there is an
  error on open and the passed in buffer is smaller than _POSIX2_LINE_MAX.
- The multicast routing code doesn't fallback to kvm on live kernels if
  the sysctl fails.  Keeping this made the code rather hairy, and netstat
  is already tied to the kernel ABI anyway (even when using sysctl's since
  things like xinpcb contain an inpcb) so any kernels this is run against
  that have the multicast routing stuff should have the sysctls.
- Don't try to dig around in the kernel linker in the netgraph PCB routine
  for core dumps.

Other notes:
- sctp's PCB routine only works on live kernels, it looked rather
  complicated to generate all the same stuff via KVM.  Someone can always
  add it later if desired though.
- Fix the ipsec removal bug where N_xxx for IPSEC stats weren't renumbered.
- Use sysctlbyname() everywhere rather than hardcoded mib values.

871f1ddd46 Restore the value of ar.rnat after the assignment to ar.bspstore.
The SDM states that writing to ar.bspstore invalidates the ar.rnat
register as a side-effect. This was interpreted as "bits in the
ar.rnat register that correspond to registers whose value is on
the stack are undefined'. Since we keep the kernel stack NaT-
aligned with the user stack (i.e. the lower 9 bits of the backing
store pointer remain unchanged when we switch to the kernel stack)
bits that need preserving would be preserved.

That interpretation is questionable. So, now, the interpretation
is more absolute: ar.rnat is undefined after writing to ar.bspstore.
As such, we write the saved value of ar.rnat back to ar.rnat after
writing to ar.bspstore.

away that it may be easily reattached to the build before 7.1 if
appropriate locking is added.  Specifics:

- Don't install netatm include files
- Disconnect netatm command line management tools
- Don't build libatm
- Don't include ATM parts in rescue or sysinstall
- Don't install sample configuration files and documents
- Don't build kernel support as a module or in NOTES
- Don't build netgraph wrapper nodes for netatm

This removes the last remaining consumer of NET_NEEDS_GIANT.
