84db023ec1 Assume a big-endian default on MIPS and drop the "eb" suffix from MACHINE_ARCH.
This makes our naming scheme more closely match other systems and the
expectations of much third-party software.  MIPS builds which are little-endian
should require and exhibit no changes.  Big-endian TARGET_ARCHes must be
changed:
	From:		To:
	mipseb		mips
	mipsn32eb	mipsn32
	mips64eb	mips64

An entry has been added to UPDATING and some foot-shooting protection (complete
with warnings which should become errors in the near future) to the top-level
base system Makefile.

9c170fd168 Disable the option VFS_ALLOW_NONMPSAFE by default on all the supported
platforms.
This will make every attempt to mount a non-mpsafe filesystem to the
kernel forbidden, unless it is expressely compiled with
VFS_ALLOW_NONMPSAFE option.

This patch is part of the effort of killing non-MPSAFE filesystems
from the tree.

No MFC is expected for this patch.

c7e41c8b50 Introduce VOP_UNP_BIND(), VOP_UNP_CONNECT(), and VOP_UNP_DETACH()
operations for setting and accessing vnode's v_socket field.

The operations are necessary to implement proper unix socket handling
on layered file systems like nullfs(5).

This change fixes the long standing issue with nullfs(5) being in that
unix sockets did not work between lower and upper layers: if we bound
to a socket on the lower layer we could connect only to the lower
path; if we bound to the upper layer we could connect only to the
upper path. The new behavior is one can connect to both the lower and
the upper paths regardless what layer path one binds to.

ca1672da93 Switch getifaddrs(3) to the new API introduced in r231505. Also remove
conditional code parts not used by or applicable to FreeBSD.

The new implementation is supposed to be able to cope with changes to
the 'l' versions of the msghdr structs now used as well as to if_data
allowing future changes without breaking things.

08b68b0e4c A major overhaul of the CARP implementation. The ip_carp.c was started
from scratch, copying needed functionality from the old implemenation
on demand, with a thorough review of all code. The main change is that
interface layer has been removed from the CARP. Now redundant addresses
are configured exactly on the interfaces, they run on.

The CARP configuration itself is, as before, configured and read via
SIOCSVH/SIOCGVH ioctls. A new prefix created with SIOCAIFADDR or
SIOCAIFADDR_IN6 may now be configured to a particular virtual host id,
which makes the prefix redundant.

ifconfig(8) semantics has been changed too: now one doesn't need
to clone carpXX interface, he/she should directly configure a vhid
on a Ethernet interface.

To supply vhid data from the kernel to an application the getifaddrs(8)
function had been changed to pass ifam_data with each address. [1]

The new implementation definitely closes all PRs related to carp(4)
being an interface, and may close several others. It also allows
to run a single redundant IP per interface.

Big thanks to Bjoern Zeeb for his help with inet6 part of patch, for
idea on using ifam_data and for several rounds of reviewing!

4d30adc494 Modify vfs_register() to use a hash calculation
on vfc_name to set vfc_typenum, so that vfc_typenum doesn't
change when file systems are loaded in different orders. This
keeps NFS file handles from changing, for file systems that
use vfc_typenum in their fsid. This change is controlled via
a loader.conf variable called vfs.typenumhash, since vfc_typenum
will change once when this is enabled. It defaults to 1 for
9.0, but will default to 0 when MFC'd to stable/8.

234dab4a82 remove code for dynamic offlining/onlining of CPUs on x86
The code has definitely been broken for SCHED_ULE, which is a default
scheduler.  It may have been broken for SCHED_4BSD in more subtle ways,
e.g. with manually configured CPU affinities and for interrupt devilery
purposes.
We still provide a way to disable individual CPUs or all hyperthreading
"twin" CPUs before SMP startup.  See the UPDATING entry for details.

Interaction between building CPU topology and disabling CPUs still
remains fuzzy: topology is first built using all availble CPUs and then
the disabled CPUs should be "subtracted" from it.  That doesn't work
well if the resulting topology becomes non-uniform.

This work is done in cooperation with Attilio Rao who in addition to
reviewing also provided parts of code.

4309e17add This patch changes head so that the default NFS client is now the new
NFS client (which I guess is no longer experimental). The fstype "newnfs"
is now "nfs" and the regular/old NFS client is now fstype "oldnfs".
Although mounts via fstype "nfs" will usually work without userland
changes, an updated mount_nfs(8) binary is needed for kernels built with
"options NFSCL" but not "options NFSCLIENT". Updated mount_nfs(8) and
mount(8) binaries are needed to do mounts for fstype "oldnfs".
The GENERIC kernel configs have been changed to use options
NFSCL and NFSD (the new client and server) instead of NFSCLIENT and NFSSERVER.
For kernels being used on diskless NFS root systems, "options NFSCL"
must be in the kernel config.

other places, make sure to update them respectively (adX -> adaY,
acdX -> cdY, afdX -> daY, astX -> saY, where 'Y's are the sequential
numbers for each type in order of detection, unless configured otherwise
with tunables, see cam(4)).

ataraid(4) functionality is now supported by the RAID GEOM class.
To use it you can load geom_raid kernel module and use graid(8) tool

efd4fc3fb3 o Flesh out the generic IEEE 802.3 annex 31B full duplex flow control
support in mii(4):
  - Merge generic flow control advertisement (which can be enabled by
    passing by MIIF_DOPAUSE to mii_attach(9)) and parsing support from
    NetBSD into mii_physubr.c and ukphy_subr.c. Unlike as in NetBSD,
    IFM_FLOW isn't implemented as a global option via the "don't care
    mask" but instead as a media specific option this. This has the
    following advantages:
    o allows flow control advertisement with autonegotiation to be
      turned on and off via ifconfig(8) with the default typically
      being off (though MIIF_FORCEPAUSE has been added causing flow
      control to be always advertised, allowing to easily MFC this
      changes for drivers that previously used home-grown support for
      flow control that behaved that way without breaking POLA)
    o allows to deal with PHY drivers where flow control advertisement
      with manual selection doesn't work or at least isn't implemented,
      like it's the case with brgphy(4), e1000phy(4) and ip1000phy(4),
      by setting MIIF_NOMANPAUSE
    o the available combinations of media options are readily available
      from the `ifconfig -m` output
  - Add IFM_FLOW to IFM_SHARED_OPTION_DESCRIPTIONS and IFM_ETH_RXPAUSE
    and IFM_ETH_TXPAUSE to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so
    these are understood by ifconfig(8).
o Make the master/slave support in mii(4) actually usable:
  - Change IFM_ETH_MASTER from being implemented as a global option via
    the "don't care mask" to a media specific one as it actually is only
    applicable to IFM_1000_T to date.
  - Let mii_phy_setmedia() set GTCR_MAN_MS in IFM_1000_T slave mode to
    actually configure manually selected slave mode (like we also do in
    the PHY specific implementations).
  - Add IFM_ETH_MASTER to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so it
    is understood by ifconfig(8).
o Switch bge(4), bce(4), msk(4), nfe(4) and stge(4) along with brgphy(4),
  e1000phy(4) and ip1000phy(4) to use the generic flow control support
  instead of home-grown solutions via IFM_FLAGs. This includes changing
  these PHY drivers and smcphy(4) to no longer unconditionally advertise
  support for flow control but only if the selected media has IFM_FLOW
  set (or MIIF_FORCEPAUSE is set) and implemented for these media variants,
  i.e. typically only for copper.
o Switch brgphy(4), ciphy(4), e1000phy(4) and ip1000phy(4) to report and
  set IFM_1000_T master mode via IFM_ETH_MASTER instead of via IFF_LINK0
  and some IFM_FLAGn.
o Switch brgphy(4) to add at least the the supported copper media based on
  the contents of the BMSR via mii_phy_add_media() instead of hardcoding
  them. The latter approach seems to have developed historically, besides
  causing unnecessary code duplication it was also undesirable because
  brgphy_mii_phy_auto() already based the capability advertisement on the
  contents of the BMSR though.
o Let brgphy(4) set IFM_1000_T master mode on all supported PHY and not
  just BCM5701. Apparently this was a misinterpretation of a workaround
  in the Linux tg3 driver; BCM5701 seem to require RGPHY_1000CTL_MSE and
  BRGPHY_1000CTL_MSC to be set when configuring autonegotiation but
  this doesn't mean we can't set these as well on other PHYs for manual
  media selection.
o Let ukphy_status() report IFM_1000_T master mode via IFM_ETH_MASTER so
  IFM_1000_T master mode support now is generally available with all PHY
  drivers.
o Don't let e1000phy(4) set master/slave bits for IFM_1000_SX as it's
  not applicable there.
