This patch updates the fc_transport with statistics for local FC ports
(e.g. Hosts).  The statistics are defined per HBAAPI v2.0 definitions.

Caveats:
------------
- The information below is supplied by a simple test driver 
that does not
  talk to real hardware, but fully acts as a LLDD that supports the
  fc transport.


This patch results in the following in /sys/class:

Len Brown convinced me that the problem with disabling
PCI routing entries wasn't the disable as much as the
fact that ELCR needs to be updated when removing the PCI
routing. So this reverts the previous cset and updates
ELCR as suggested by Len.

Ignore offline CPUs when registering IOSAPIC interrupts.  We previously
directed interrupts even to offline CPUs, which means that if you have some
unused CPUs (e.g., you used "maxcpus="), some interrupts won't work.

This really hurts because distro installs typically use "maxcpus=1".

This fixes at least some interrupt polarity setup cases.
The ACPI guys may want to eventually do this differently, but
in the meantime this makes ACPI behaviour closer to non-ACPI
behaviour, and fixes known problems.

I'll further argue that this protects non-PCI devices that may
just share the irq routing from being screwed, but that may or
may not be an argument that everybody buys into.

This depends on the previous ptrace single-step cleanup,
and makes sure that signal handling does not lose TF events.

This allows debuggers to trace programs that set TF on their
own.

(This makes the naming of "DTRACE" purely historical, since
on x86 it now means "single step in progress").

We just spent some days fighting a rare race in one of the distro's who backported
some of timer.c from 2.6 to 2.4 (though they missed a bit).

The actual race we found didn't happen in 2.6 _but_ code inspection showed that a
similar race is still present in 2.6, explanation below:

Code removing a timer from a list (run_timers or del_timer) takes that CPU list
lock, does list_del, then timer->base = NULL.

It is mandatory that this timer->base = NULL is visible to other CPUs only after
the list_del() is complete. If not, then mod timer could see it NULL, thus take it's
own CPU list lock and not the one for the CPU the timer was beeing removed from the
list, and thus the list_add in mod_timer() could race with the list_del() from
run_timers() or del_timer().

Our race happened with run_timers(), which _DOES_ contain a proper smp_wmb() in the
right spot in 2.6, but didn't in the "backport" we were fighting with.

However, del_timer() doesn't have such a barrier, and thus is subject to this race in
2.6 as well. This patch fixes it.

there was a command line, and not use the built-in one. This patch fixes it.
