ef0ebfc351 Add two new kernel options to allow rudimentary profiling of the internal
hash tables used in the sleep queue and turnstile code.  Each option adds
a sysctl tree under debug containing the maximum depth of any bucket in
the hash table as well as a separate node for each bucket (or chain)
containing the current depth and maximum depth for that bucket.

I have left default value at '4' as higher values can consume a more
than is acceptable amount of CPU, and we don't have a consensus yet

6d90faf3d8 Add support for TCP Selective Acknowledgements. The work for this
originated on RELENG_4 and was ported to -CURRENT.

The scoreboarding code was obtained from OpenBSD, and many
of the remaining changes were inspired by OpenBSD, but not
taken directly from there.

You can enable/disable sack using net.inet.tcp.do_sack. You can
also limit the number of sack holes that all senders can have in
the scoreboard with net.inet.tcp.sackhole_limit.

f889d2ef8d Major overhaul of pseudo-interface cloning. Highlights include:
- Split the code out into if_clone.[ch].
 - Locked struct if_clone. [1]
 - Add a per-cloner match function rather then simply matching names of
   the form <name><unit> and <name>.
 - Use the match function to allow creation of <interface>.<tag>
   vlan interfaces.  The old way is preserved unchanged!
 - Also the match function to allow creation of stf(4) interfaces named
   stf0, stf, or 6to4.  This is the only major user visible change in
   that "ifconfig stf" creates the interface stf rather then stf0 and
   does not print "stf0" to stdout.
 - Allow destroy functions to fail so they can refuse to delete
   interfaces.  Currently, we forbid the deletion of interfaces which
   were created in the init function, particularly lo0, pflog0, and
   pfsync0.  In the case of lo0 this was a panic implementation so it
   does not count as a user visiable change. :-)
 - Since most interfaces do not need the new functionality, an family of
   wrapper functions, ifc_simple_*(), were created to wrap old style
   cloner functions.
 - The IF_CLONE_INITIALIZER macro is replaced with a new incompatible
   IFC_CLONE_INITIALIZER and ifc_simple consumers use IFC_SIMPLE_DECLARE
   instead.

5526395941 Fix the following error:
ld: locore.o: non-pic code with imm relocation against dynamic
	symbol `__gp'

With binutils 2.15, ld(1) defines the implicit/automatic symbol __gp
as a dynamic symbol and thus will now complain when used in a non-PIC
fashion (the immediate relocation used to set the GP register). Resolve
this by defining __gp in the linker script. Make sure __gp is aligned
on a 16-byte boundary.

Note: the 0x200000 magic offset is due to having a 22-bit GP-relative
relocation. The GOT will be accessed with negative offsets from GP.

b8b3323469 Add a new driver to support IP over firewire. This driver is intended to
conform to the rfc2734 and rfc3146 standard for IP over firewire and
should eventually supercede the fwe driver. Right now the broadcast
channel number is hardwired and we don't support MCAP for multicast
channel allocation - more infrastructure is required in the firewire
code itself to fix these problems.

6732641e0a Step 1 in moving EISA devices to kobj/newbus. Use kobj methods for
all of the interface between the driver and the bus.  This will enable
us to stop special casing eisa bus attachments in modules and treat them
like we treat all other busses.

In the longer run, we need to eliminate much (all?) of these interfaces
and switch to using the standard bus_alloc_resource(), but that's not
done right now.

099a0e588c Bring in mbuma to replace mballoc.
mbuma is an Mbuf & Cluster allocator built on top of a number of
extensions to the UMA framework, all included herein.

Extensions to UMA worth noting:
  - Better layering between slab <-> zone caches; introduce
    Keg structure which splits off slab cache away from the
    zone structure and allows multiple zones to be stacked
    on top of a single Keg (single type of slab cache);
    perhaps we should look into defining a subset API on
    top of the Keg for special use by malloc(9),
    for example.
  - UMA_ZONE_REFCNT zones can now be added, and reference
    counters automagically allocated for them within the end
    of the associated slab structures.  uma_find_refcnt()
    does a kextract to fetch the slab struct reference from
    the underlying page, and lookup the corresponding refcnt.

mbuma things worth noting:
  - integrates mbuf & cluster allocations with extended UMA
    and provides caches for commonly-allocated items; defines
    several zones (two primary, one secondary) and two kegs.
  - change up certain code paths that always used to do:
    m_get() + m_clget() to instead just use m_getcl() and
    try to take advantage of the newly defined secondary
    Packet zone.
  - netstat(1) and systat(1) quickly hacked up to do basic
    stat reporting but additional stats work needs to be
    done once some other details within UMA have been taken
    care of and it becomes clearer to how stats will work
    within the modified framework.

From the user perspective, one implication is that the
NMBCLUSTERS compile-time option is no longer used.  The
maximum number of clusters is still capped off according
to maxusers, but it can be made unlimited by setting
the kern.ipc.nmbclusters boot-time tunable to zero.
Work should be done to write an appropriate sysctl
handler allowing dynamic tuning of kern.ipc.nmbclusters
at runtime.

Additional things worth noting/known issues (READ):
   - One report of 'ips' (ServeRAID) driver acting really
     slow in conjunction with mbuma.  Need more data.
     Latest report is that ips is equally sucking with
     and without mbuma.
   - Giant leak in NFS code sometimes occurs, can't
     reproduce but currently analyzing; brueffer is
     able to reproduce but THIS IS NOT an mbuma-specific
     problem and currently occurs even WITHOUT mbuma.
   - Issues in network locking: there is at least one
     code path in the rip code where one or more locks
     are acquired and we end up in m_prepend() with
     M_WAITOK, which causes WITNESS to whine from within
     UMA.  Current temporary solution: force all UMA
     allocations to be M_NOWAIT from within UMA for now
     to avoid deadlocks unless WITNESS is defined and we
     can determine with certainty that we're not holding
     any locks when we're M_WAITOK.
   - I've seen at least one weird socketbuffer empty-but-
     mbuf-still-attached panic.  I don't believe this
     to be related to mbuma but please keep your eyes
     open, turn on debugging, and capture crash dumps.

This change removes more code than it adds.

A paper is available detailing the change and considering
various performance issues, it was presented at BSDCan2004:

details, as well as credits.

30346936cf MFamd64:
Fixed profiling of trap, syscall and interrupt handlers and some
ordinary functions, essentially by backing out half of rev.1.106 of
i386/exception.s.  The handlers must be between certain labels for
the purposes of profiling, and this was broken by scattering them in
separately compiled .s files, especially for ordinary functions that
ended up between the labels.  Merge the files by #including them as
before, except with different pathnames and better comments and
organization.  Changes to the scattered files are minimal -- just
move the labels to the file that does the #includes.

This also partly fixes profiling of IPIs -- all IPI handlers are now
correctly classified as interrupt handlers, but many are still missing
mcount calls.

vm86bios.s is included as before, but it is now between the labels for
interrupt handlers again, which seems to be wrong since half of it is
for a non-interrupt handler.

478fee28e6 Build prof_machdep.c if profiling.
Kernel profiling for amd64's (normal and high resolution) should now
compile and work as (un)well as on i386's.  It works better than user
profiling because:
- it uses _cyg_profile_func_*() instead of .mcount(), so it doesn't suffer
  from gcc misspelling .mcount as mcount.
- it doesn't neglect saving %rax in .mcount().

The SMP case hasn't been tested.  The high resolution subcase of this uses
the i8254, and as on i386's, the locking for this is deficient and the
i8254 is too inefficient.  The acpi timer is also too inefficient.
