83cb5bae96 - CTF knob is now implemented using common scheme: MK_CTF=yes/no is
defined based on WITH/WITHOUT_CTF settings, default is WITHOUT_CTF,
NO_CTF overrides WITH_CTF (used by Makefile.inc1)
- CTFCONVERT_CMD/NORMAL_CTFCONVERT are now defined to empty string
if make(1) can handle empty commands

1a5d0ec1d0 CTFCONVERT_CMD=... hack does not work sufficiently well in parallel builds.

78e7e3ecb5 - fix WITH_CTF when specified in /etc/src.conf [1]
- CTFCONVERT_CMD=... is a hack (should be defined to empty string instead):
make(1) should be taught to ignore empty commands silently in compat mode
(as it does in !compat mode, GNU make also silently ignores empty commands)
and to skip printing empty commands in !compat mode
- config(8) should generate ${NORMAL_CTFCONVERT} invocation without '@':
this will allow to simplify kern.pre.mk even more and lessen the number
of shell invocations during kernel build when CTF is turned off
- WITH_CTF can now be converted to usual MK_CTF=yes/no infrastructure

cd49c2e840 Conditionalize ctfconvert/ctfmerge runs on make level (.if/.endif) instead
of executing a shell on every object or executable/library file.

This shaves off more than 30,000 shell invocations during buildworld.

1ade594798 Allow NO_FOO to override WITH_FOO that could be specified in /etc/src.conf.
This is required to override knobs (e.g. WITH_PROFILE) during buildworld
stages in Makefile.inc1 (otherwise the build is stopped due to both WITH_FOO
and WITHOUT_FOO defined).

49c8e5e77e Fix breakage after r227983; lib/libcxxrt still got built, because it was
not disabled in the usual way (by adding it to __DEFAULT_NO_OPTIONS in

Makefile.inc1 was incorrect.

MK_LIBCPLUSPLUS=yes to enable).  This is a work-in-progress.  It works for
me, but is not guaranteed to work for anyone else and may eat your dog.

68b8534bdf Bring in support for netmap, a framework for very efficient packet
I/O from userspace, capable of line rate at 10G, see

	http://info.iet.unipi.it/~luigi/netmap/

At this time I am bringing in only the generic code (sys/dev/netmap/
plus two headers under sys/net/), and some sample applications in
tools/tools/netmap. There is also a manpage in share/man/man4 [1]

In order to make use of the framework you need to build a kernel
with "device netmap", and patch individual drivers with the code
that you can find in

	sys/dev/netmap/head.diff

The file will go away as the relevant pieces are committed to
the various device drivers, which should happen in a few days
after talking to the driver maintainers.

Netmap support is available at the moment for Intel 10G and 1G
cards (ixgbe, em/lem/igb), and for the Realtek 1G card ("re").
I have partial patches for "bge" and am starting to work on "cxgbe".
Hopefully changes are trivial enough so interested third parties
can submit their patches. Interested people can contact me
for advice on how to add netmap support to specific devices.

CREDITS:
    Netmap has been developed by Luigi Rizzo and other collaborators
    at the Universita` di Pisa, and supported by EU project CHANGE
    (http://www.change-project.eu/)
    The code is distributed under a BSD Copyright.

[1] In my opinion is a bad idea to have all manpage in one directory.
  We should place kernel documentation in the same dir that contains
  the code, which would make it much simpler to keep doc and code
  in sync, reduce the clutter in share/man/ and incidentally is
  the policy used for all of userspace code.
  Makefiles and doc tools can be trivially adjusted to find the
  manpages in the relevant subdirs.

d7ecd801ed As it turns out, r186347 actually is insufficient to avoid the use of the
curthread-accessing part of mtx_{,un}lock(9) when using a r210623-style
curthread implementation on sparc64, crashing the kernel in its early
cycles as PCPU isn't set up, yet (and can't be set up as OFW is one of the
things we need for that, which leads to a chicken-and-egg problem). What
happens is that due to the fact that the idea of r210623 actually is to
allow the compiler to cache invocations of curthread, it factors out
obtaining curthread needed for both mtx_lock(9) and mtx_unlock(9) to
before the branch based on kobj_mutex_inited when compiling the kernel
without the debugging options. So change kobj_class_compile_static(9)
to just never acquire kobj_mtx, effectively restricting it to its
documented use, and add a kobj_init_static(9) for initializing objects
using a class compiled with the former and that also avoids using mutex(9)
(and malloc(9)). Also assert in both of these functions that they are
used in their intended way only.
While at it, inline kobj_register_method() and kobj_unregister_method()
as there wasn't much point for factoring them out in the first place
and so that a reader of the code has to figure out the locking for
fewer functions missing a KOBJ_ASSERT.
Tested on powerpc{,64} by andreast.
