Glanced over quickly by martin@ and joerg@.

cegger c479884027 change nfs boot behaviour to automatically try next boot method if boot information are incomplete to succeed.
That way, it is possible combine static and dhcp boot:
  For example, to boot diskless you can specify the nfs-server and the rootpath statically. All other information will be taken via dhcp.

Patch has been presented on port-xen, tech-kern and tech-net:

bouyer a92a400fbf Add a new BOOTSTATIC flag, NFS_BOOTSTATIC_NOSTATIC, which causes
nfs_bootstatic() to abort with EOPNOTSUPP. This allows a callback to
say that there is no bootstatic config, and the next NFS boot method should
be tried.

manu 31b57f40ff Add the TFTPROOT kernel option for TFTP'ing root RAMdisk at root mount time.
This allows working around situations where a kernel with embedded RAMdisk
cannot be booted by the bootloader because the RAMdisk is too big.

jonathan 230fb9b8ab Eliminate several uses of `curproc' from the socket-layer code and from NFS.
Add a new explicit `struct proc *p' argument to socreate(), sosend().
Use that argument instead of curproc. Follow-on changes to pass that
argument to socreate(), sosend(), and (*so->so_send)() calls.
These changes reviewed and independently recoded  by Matt Thomas.

Changes to soreceive() and (*dom->dom_exernalize() from Matt Thomas:
pass soreceive()'s struct uio* uio->uio_procp to unp_externalize().
Eliminate curproc from unp_externalize.   Also, now soreceive() uses
its uio->uio_procp value, pass that same value downward to
((pr->pru_usrreq)() calls for consistency, instead of (struct proc * )0.

Similar changes in sys/nfs to eliminate (most) uses of curproc,
either via the req-> r_procp field of a struct nfsreq *req argument,
or by passing down new explicit struct proc * arguments.

Reviewed by: Matt Thomas, posted to tech-kern.
NB: The (*pr->pru_usrreq)() change should be tested on more (all!) protocols.

cl 638599b22b Add static nfs boot configuration, from the kernel config file or from
a driver selectable callback function.  This is used in the Xen port to
allow controlling  the domain's network setup from the domain building
environment at domain creation (vs. having to maintain/change this on a
dhcp server).  The Xen network driver parses a command line passed in
from the domain builder.

fvdl d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.

darrenr 960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

drochner 27098b1199 restructure the diskless NFS boot code to keep track of the used
interface and the address allocated, to roll everything back if the
mount fails:
-put an interface pointer into "struct nfs_diskless" to have it
 available for cleanup, don't pass it around anymore where the
 "struct nfs_diskless" is already passed
-add a "cleanup" function which shuts the interface down
-in the protocol-specific parts, either return with "everything
 ready" or "completely shut down"
-use common functions for interface initialization and shutdown
-add a function to delete all routes associate to an interface
 (why is this necessary and not done by ~IFF_UP?)

drochner 40db8a98f5 1. Allow to set a netmask (option NFS_BOOT_NETMASK) for the booting
interface. Without this, NFS_BOOT_NETMASK could be useless in
   subnetting envirinment.
2. Comment out unneeded NFS swap related stuff.
   Closes PR kern/3918.

gwr 01adc15274 Minor reorganization of nfs_mountroot code to simplify BOOTP support.
The RPC/bootparamd calls to get the root and swap paths are now done
in nfs_boot_init() instead of nfs_boot_getfh(), so the latter now just
does the RPC/mountd call.  Also changed some panics into error returns.

fvdl 735944405b Enhancements from Matthias Drochner:
- Try V3 first for diskless booting. Fall back to V2 if V3 fails.
	- optionally (option NFS_BOOT_TCP) try a TCP mount first
	  for diskless booting. Fall back to UDP if it fails.
	- Enable switching between UDP and TCP for remounts.
