59aa14a91d Implementation of the upcoming Wireless Mesh standard, 802.11s, on the
net80211 wireless stack. This work is based on the March 2009 D3.0 draft
standard. This standard is expected to become final next year.
This includes two main net80211 modules, ieee80211_mesh.c
which deals with peer link management, link metric calculation,
routing table control and mesh configuration and ieee80211_hwmp.c
which deals with the actually routing process on the mesh network.
HWMP is the mandatory routing protocol on by the mesh standard, but
others, such as RA-OLSR, can be implemented.

Authentication and encryption are not implemented.

There are several scripts under tools/tools/net80211/scripts that can be
used to test different mesh network topologies and they also teach you
how to setup a mesh vap (for the impatient: ifconfig wlan0 create
wlandev ... wlanmode mesh).

A new build option is available: IEEE80211_SUPPORT_MESH and it's enabled
by default on GENERIC kernels for i386, amd64, sparc64 and pc98.

Drivers that support mesh networks right now are: ath, ral and mwl.

More information at: http://wiki.freebsd.org/WifiMesh

Please note that this work is experimental. Also, please note that
bridging a mesh vap with another network interface is not yet supported.

Many thanks to the FreeBSD Foundation for sponsoring this project and to
Sam Leffler for his support.
Also, I would like to thank Gateworks Corporation for sending me a
Cambria board which was used during the development of this project.

49c8326a79 - Work around the broken loader behavior of not demapping no longer
used kernel TLB slots when unloading the kernel or modules, which
  results in havoc when loading a kernel and modules which take up
  less TLB slots afterwards as the unused but locked ones aren't
  accounted for in virtual_avail. Eventually this should be fixed
  in the loader which isn't straight forward though and the kernel
  should be robust against this anyway. [1]
- Ensure that the addresses allocated directly from phys_avail[] by
  pmap_bootstrap_alloc() are always colored properly. This implicit
  assumption was broken in r194784 as unlike the other consumers the
  DPCPU area allocated for the BSP isn't a multiple of PAGE_SIZE *
  DCACHE_COLORS. [2]
- Remove the no longer used global msgbuf_phys.
- Remove the redundant ekva parameter of pmap_bootstrap_alloc().
- Correct some outdated function names in ktr(9) invocations.

e999111ae7 This change is the next step in implementing the cache control functionality
required by video card drivers.  Specifically, this change introduces
vm_cache_mode_t with an appropriate VM_CACHE_DEFAULT definition on all
architectures.  In addition, this changes adds a vm_cache_mode_t parameter
to kmem_alloc_contig() and vm_phys_alloc_contig().  These will be the
interfaces for allocating mapped kernel memory and physical memory,
respectively, with non-default cache modes.

16d58437ed o merge from amd64:
- r187144: Add a reference to the config(5) manpage and
    to the "env" kernel config option.
  - Add/enable the default USB drivers. Originally the USB
    controller and keyboard drivers were disabled as these
    interacted badly with the Open Firmware console driver,
    i.e. caused the keyboard to not work with ofw_console(4).
    Even when switch to uart(4) and the frame buffer drivers
    most of the USB drivers still were kept disabled as
    several of them, amongst others all of the drivers for
    USB Ethernet controllers, weren't endian clean. With the
    new USB stack these problem should be gone now so there's
    no longer a reason to not include the same set of USB
    drivers amd64 does.
o Remove the commented out device ofw_console; apart from it
  being currently broken by some TTY changes one really needs
  to know how to actually enable and make it work correctly.

186cff43e3 Unbreak sparc64 after the swap accounting changes: mark kernel_map
entries allocated for translations in pmap_init() as MAP_NOFAULT. This
prevents vm_map_insert from trying to account the entries for swap
usage, that is both wrong and too early to work.

While there, change FALSE to VMFS_NO_SPACE.

50c202c592 Implement a facility for dynamic per-cpu variables.
- Modules and kernel code alike may use DPCPU_DEFINE(),
   DPCPU_GET(), DPCPU_SET(), etc. akin to the statically defined
   PCPU_*.  Requires only one extra instruction more than PCPU_* and is
   virtually the same as __thread for builtin and much faster for shared
   objects.  DPCPU variables can be initialized when defined.
 - Modules are supported by relocating the module's per-cpu linker set
   over space reserved in the kernel.  Modules may fail to load if there
   is insufficient space available.
 - Track space available for modules with a one-off extent allocator.
   Free may block for memory to allocate space for an extent.

bd875f5f13 Remove MAC kernel config files and add "options MAC" to GENERIC, with the
goal of shipping 8.0 with MAC support in the default kernel.  No policies
will be compiled in or enabled by default, but it will now be possible to
load them at boot or runtime without a kernel recompile.

While the framework is not believed to impose measurable overhead when no
policies are loaded (a result of optimization over the past few months in
HEAD), we'll continue to benchmark and optimize as the release approaches.
Please keep an eye out for performance or functionality regressions that
could be a result of this change.

76ca6f88da Place hostnames and similar information fully under the prison system.
The system hostname is now stored in prison0, and the global variable
"hostname" has been removed, as has the hostname_mtx mutex.  Jails may
have their own host information, or they may inherit it from the
parent/system.  The proper way to read the hostname is via
getcredhostname(), which will copy either the hostname associated with
the passed cred, or the system hostname if you pass NULL.  The system
hostname can still be accessed directly (and without locking) at
prison0.pr_host, but that should be avoided where possible.

The "similar information" referred to is domainname, hostid, and
hostuuid, which have also become prison parameters and had their
associated global variables removed.

dbb95048da Add cpu_flush_dcache() for use after non-DMA based I/O so that a
possible future I-cache coherency operation can succeed. On ARM
for example the L1 cache can be (is) virtually mapped, which
means that any I/O that uses temporary mappings will not see the
I-cache made coherent. On ia64 a similar behaviour has been
observed. By flushing the D-cache, execution of binaries backed
by md(4) and/or NFS work reliably.
For Book-E (powerpc), execution over NFS exhibits SIGILL once in
a while as well, though cpu_flush_dcache() hasn't been implemented
yet.

Doing an explicit D-cache flush as part of the non-DMA based I/O
read operation eliminates the need to do it as part of the
I-cache coherency operation itself and as such avoids pessimizing
the DMA-based I/O read operations for which D-cache are already
flushed/invalidated. It also allows future optimizations whereby
the bcopy() followed by the D-cache flush can be integrated in a
single operation, which could be implemented using on-chips DMA
engines, by-passing the D-cache altogether.

1eb3155347 Just like in cpu_halt(), use cpu_shutdown() rather than ofw_exit()
directly in cpu_reset() in order to idle the APs before exiting
the kernel and letting the BSP enter the firmware so that processes
like init(8) which still might be running on an AP at that point
don't cause a panic there when it crashes due to the fact it no
longer can be supported by the kernel.

b477a2c916 - According to comments in OpenBSD, E{2,4}50 tend to have fragile
firmware versions which wedge when using the OFW test service,
  so given that we don't really depend on SUNW,stop-self just nuke
  it altogether instead of risking problems.
- At least Fire V880 have a small hardware glitch which causes the
  reception of IDR_NACKs for CPUs we actually haven't tried to send
  an IPI to, even not as part of the initial try. According to tests
  this apparently can be safely ignored though, so just return if
  checking for the individual IDR_NACKs indicates no outstanding
  dispatch. Serializing the sending of IPIs between MD and MI code
  by the combined usage of smp_ipi_mtx makes no difference to this
  phenomenon. [1]
- Provide relevant debugging bits already with the initial panic
  in case of problems with the IPI dispatch, which would have
  allowed to diagnose the above problem without a specially built
  kernel.
- In case of cheetah_ipi_selected() base the delay we wait for
  other CPUs which also might want to dispatch IPIs on the total
  amount of CPUs instead of just the number of CPUs we let this
  CPU send IPIs to because in the worst case all CPUs also want
  to IPI us at the same time.
