90d9802fe7 Make the number of loopback interfaces dynamically tunable. Why one

This could be used as an example of how to do this in other drivers,

2a9737202a This patch reestablishes the spec_fsync() guarentee that synchronous 
fsyncs, which typically occur during unmounting, will drain all dirty
buffers even if it takes multiple passes to do so.  The guarentee was
mangled by the last patch which solved a problem due to -current disabling
interrupts while holding giant (which caused an infinite spin loop waiting for
I/O to complete).  -stable does not have either patch, but has a similar
bug in the original spec_fsync() code which is triggered by a bug in the
softupdates umount code, a fix for which will be committed to -current
as soon as Kirk stamps it.  Then both solutions will be MFC'd to -stable.

-stable currently suffers from a combination of the softupdates bug and
a small window of opportunity in the original spec_fsync() code, and -stable
also suffers from the spin-loop bug but since interrupts are enabled the
spin resolves itself in a few milliseconds.

5bcc1e51a0 Don't hard-code alignment and data declarations valid for 64-bit

3c9013e257 A couple of chip errata work-arounds refined: 
- When used on a 33MHz PCI BUS, the 53C1010-66 revision 0
  requires extra clocks to be inserted in data out phase.
  Revision 1 is fixed.
- The 53C1010-33 revision 1 requires internal cycles to be
  disabled due to possible contentions on IO registers.
  Revision 2 is fixed.
Fix:
- The probing of HVD from GPIO3 bit by the driver was reversed.
  The driver could misprobe the bus mode of a 825 or 875 chip
  that was not previously initialized (no BIOS for example).

The new method is 'flood' (in addition to the old round-robin)
in which incoming packets are sent to more than one outgoing hook.
(I'm not sure what Rogier is using this for but it seems generally useful
and isn't much extra)

84e11fbc2e Move the setting of curproc to idleproc up earlier in ap_init(). The 
problem is that a mutex lock, prior to this change, is acquired before
the curproc is set to idleproc, so we mess ourselves up by calling
the mutex lock routine with curproc == NULL.

Moving it up after the aps_ready spin-wait has us hopefully setting it
after idleproc is setup.
