4db6fc7542 Make need_resched() take a "struct cpu_info *" argument. This 
causes gives a primitive form of processor affinity.  Its use in
roundrobin() still needs some work.

1d8f5f2ea3 Pretend to do something useful (just fill in oldsigaction with SIG_IGN and 
zeroes) if the mapped signal number comes up zero.  Previously, sigaction1()
would return an error, confusing some linux apps trying to set handlers for
"all" signals.

e03e9e8086 Rather than starting init and creating kthreads by forking and then 
doing a cpu_set_kpc(), just pass the entry point and argument all
the way down the fork path starting with fork1().  In order to
avoid special-casing the normal fork in every cpu_fork(), MI code
passes down child_return() and the child process pointer explicitly.

This fixes a race condition on multiprocessor systems; a CPU could
grab the newly created processes (which has been placed on a run queue)
before cpu_set_kpc() would be performed.

7b918b4088 New callout mechanism with two major improvements over the old 
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

600be45ffc Improve emulation of SIOCGIFHWADDR ioctl: 
* when finding an interface, try the real name first before faking eth*
 * Linux kernel returns ENODEV if the request goes to unknown interface,
   so do the same here

This change makes Linux ICA client work.

c581bf97c5 A few things to make the Linux clone(2) emulation work a bit better: 
- When the exit signal is specified to be 0, don't just assume they
  meant SIGCHLD.  In the Linux world, this appears to mean "don't deliver
  an exit signal at all".
- Simplify P_EXITSIG(); don't check against initproc here, just change
  the exit signal to SIGCHLD if reparenting to initproc.

A very simple clone(2) test program now works, and the MpegTV package
starts, but doesn't run properly yet (I believe there is a separate
bug which keeps it from working properly).
