59c50d8277 top(1): several small bugfixes and nits
- initialize all maybe uninitialized vars with bogus values. This shuts
up the compiler, and causes crashes if it changes later.
- mark noreturn as noreturn
- removed unused macro
- handle x_procstate as runtime rather than pre-processor
- avoid using void functions in condtionals

Tested with clang, gcc 7, gcc 9

This machine does not have the 'ibm,supported-tce-sizes' entries, thus, count

90d2dfab19 Merge the pNFS server code from projects/pnfs-planb-server into head.
This code merge adds a pNFS service to the NFSv4.1 server. Although it is
a large commit it should not affect behaviour for a non-pNFS NFS server.
Some documentation on how this works can be found at:
http://people.freebsd.org/~rmacklem/pnfs-planb-setup.txt
and will hopefully be turned into a proper document soon.
This is a merge of the kernel code. Userland and man page changes will
come soon, once the dust settles on this merge.
It has passed a "make universe", so I hope it will not cause build problems.
It also adds NFSv4.1 server support for the "current stateid".

Here is a brief overview of the pNFS service:
A pNFS service separates the Read/Write oeprations from all the other NFSv4.1
Metadata operations. It is hoped that this separation allows a pNFS service
to be configured that exceeds the limits of a single NFS server for either
storage capacity and/or I/O bandwidth.
It is possible to configure mirroring within the data servers (DSs) so that
the data storage file for an MDS file will be mirrored on two or more of
the DSs.
When this is used, failure of a DS will not stop the pNFS service and a
failed DS can be recovered once repaired while the pNFS service continues
to operate.  Although two way mirroring would be the norm, it is possible
to set a mirroring level of up to four or the number of DSs, whichever is
less.
The Metadata server will always be a single point of failure,
just as a single NFS server is.

A Plan B pNFS service consists of a single MetaData Server (MDS) and K
Data Servers (DS), all of which are recent FreeBSD systems.
Clients will mount the MDS as they would a single NFS server.
When files are created, the MDS creates a file tree identical to what a
single NFS server creates, except that all the regular (VREG) files will
be empty. As such, if you look at the exported tree on the MDS directly
on the MDS server (not via an NFS mount), the files will all be of size 0.
Each of these files will also have two extended attributes in the system
attribute name space:
pnfsd.dsfile - This extended attrbute stores the information that
    the MDS needs to find the data storage file(s) on DS(s) for this file.
pnfsd.dsattr - This extended attribute stores the Size, AccessTime, ModifyTime
    and Change attributes for the file, so that the MDS doesn't need to
    acquire the attributes from the DS for every Getattr operation.
For each regular (VREG) file, the MDS creates a data storage file on one
(or more if mirroring is enabled) of the DSs in one of the "dsNN"
subdirectories.  The name of this file is the file handle
of the file on the MDS in hexadecimal so that the name is unique.
The DSs use subdirectories named "ds0" to "dsN" so that no one directory
gets too large. The value of "N" is set via the sysctl vfs.nfsd.dsdirsize
on the MDS, with the default being 20.
For production servers that will store a lot of files, this value should
probably be much larger.
It can be increased when the "nfsd" daemon is not running on the MDS,
once the "dsK" directories are created.

For pNFS aware NFSv4.1 clients, the FreeBSD server will return two pieces
of information to the client that allows it to do I/O directly to the DS.
DeviceInfo - This is relatively static information that defines what a DS
             is. The critical bits of information returned by the FreeBSD
             server is the IP address of the DS and, for the Flexible
             File layout, that NFSv4.1 is to be used and that it is
             "tightly coupled".
             There is a "deviceid" which identifies the DeviceInfo.
Layout     - This is per file and can be recalled by the server when it
             is no longer valid. For the FreeBSD server, there is support
             for two types of layout, call File and Flexible File layout.
             Both allow the client to do I/O on the DS via NFSv4.1 I/O
             operations. The Flexible File layout is a more recent variant
             that allows specification of mirrors, where the client is
             expected to do writes to all mirrors to maintain them in a
             consistent state. The Flexible File layout also allows the
             client to report I/O errors for a DS back to the MDS.
             The Flexible File layout supports two variants referred to as
             "tightly coupled" vs "loosely coupled". The FreeBSD server always
             uses the "tightly coupled" variant where the client uses the
             same credentials to do I/O on the DS as it would on the MDS.
             For the "loosely coupled" variant, the layout specifies a
             synthetic user/group that the client uses to do I/O on the DS.
             The FreeBSD server does not do striping and always returns
             layouts for the entire file. The critical information in a layout
             is Read vs Read/Writea and DeviceID(s) that identify which
             DS(s) the data is stored on.

At this time, the MDS generates File Layout layouts to NFSv4.1 clients
that know how to do pNFS for the non-mirrored DS case unless the sysctl
vfs.nfsd.default_flexfile is set non-zero, in which case Flexible File
layouts are generated.
The mirrored DS configuration always generates Flexible File layouts.
For NFS clients that do not support NFSv4.1 pNFS, all I/O operations
are done against the MDS which acts as a proxy for the appropriate DS(s).
When the MDS receives an I/O RPC, it will do the RPC on the DS as a proxy.
If the DS is on the same machine, the MDS/DS will do the RPC on the DS as
a proxy and so on, until the machine runs out of some resource, such as
session slots or mbufs.
As such, DSs must be separate systems from the MDS.

0f69696824 linux64: use linux output target for linux_vdso.so
linux_vdso.so provides the vdso for the linuxulator's amd64 target and
is mapped into a Linux binary's address space.  Thus it should be a
Linux-style .so, which has the ELF OS/ABI unset.

It turns out that ELF Tool Chain elfcopy/objcopy also has a bug where
the OS/ABI field is unset, regardless of the specified --output-target,
so this change is a no-op with the default in-tree toolchain.  This is a
real fix when using external binutils, and the ELF Tool Chain bug will
be fixed in the future.

5d2791646b lualoader: More black-on-white fixes
To recap the problem: with a black-on-white xterm, the menu draws terribly.
Ideally, we would try our best for a white-on-black context for the menu
since graphics and whatnot might not be tested for other setups and there's
no reasonable way to sample the terminal at this point for the used color
scheme.

This commit attempts to address that further in two ways:
- Instead of issuing CSI bg/fg resets (CSI 39m and CSI 49m respectively for
  "default"), issue CSI bg/fg escape sequences for our expected color scheme
- Reset to *our* default color scheme before we even attempt to load the
  local module, so that we personally don't have any earlier text with the
  console default color scheme.

1463aa7444 muge.4: remove BUGS section (about link/act LEDs)
Lack of functioning link and activity LEDs on devices without an EEPROM
is expected (not a bug).  Quoting the EVB-LAN7850 User's Guide:

    When configured with the default internal register settings, the
    Ethernet Link status LEDs are not enabled.  To enable Ethernet Link
    status LEDs, enable the EEPROM.

This is an artifact of the different ways in which the evaluation board
can be used.  End-user USB-Ethernet adapters using the Microchip LAN78XX
or LAN7515 controllers should use an EEPROM or have OTP configuration,
if their product configuration does not match the boot default register
configuration.
