patch deletes quite a bit of code.

* Basic EISA bus support for the SGI Indigo-2.

*
* This code is released under both the GPL version 2 and BSD

*
* This code offers a very basic support for this EISA bus present in
* the SGI Indigo-2. It currently only supports PIO (forget about DMA
* for the time being). This is enough for a low-end ethernet card,
* but forget about your favorite SCSI card...
*
* TODO :
* - Fix bugs...
* - Add ISA support
* - Add DMA (yeah, right...).
* - Fix more bugs.

/* A lot of complication here is taken away because:
*
* 1) We handle one interrupt and return, sitting in a loop
* and moving across all the pending IRQ bits in the cause
* register is _NOT_ the answer, the common case is one
* pending IRQ so optimize in that direction.
*
* 2) We need not check against bits in the status register
* IRQ mask, that would make this routine slow as hell.
*
* 3) Linux only thinks in terms of all IRQs on or all IRQs
* off, nothing in between like BSD spl() brain-damage.
*
* Furthermore, the IRQs on the INDY look basically (barring
* software IRQs which we don't use at all) like:
*
* MIPS IRQ Source
* -------- ------
* 0 Software (ignored)
* 1 Software (ignored)
* 2 Local IRQ level zero
* 3 Local IRQ level one
* 4 8254 Timer zero
* 5 8254 Timer one
* 6 Bus Error
* 7 R4k timer (what we use)
*
* We handle the IRQ according to _our_ priority which is:
*
* Highest ---- R4k Timer
* Local IRQ zero
* Local IRQ one
* Bus Error
* 8254 Timer zero
* Lowest ---- 8254 Timer one
*
* then we just return, if multiple IRQs are pending then
* we will just take another exception, big deal.

/*
* Linux has a controller-independent x86 interrupt architecture.
* every controller has a 'controller-template', that is used
* by the main code to do the right thing. Each driver-visible
* interrupt source is transparently wired to the apropriate
* controller. Thus drivers need not be aware of the
* interrupt-controller.
*
* Various interrupt controllers we handle: 8259 PIC, SMP IO-APIC,
* PIIX4's internal 8259 PIC and SGI's Visual Workstation Cobalt (IO-)APIC.
* (IO-APICs assumed to be messaging to Pentium local-APICs)
*
* the code is designed to be easily extended with new/different
* interrupt controllers, without having to do assembly magic.
