ia64: remove support for the SGI SN2 platform 

The SGI SN2 (early Altix) is a very non-standard IA64 platform that was
at the very high end of even IA64 hardware, and has been discontinued
a long time ago.  Remove it because there no upstream users left, and it
has magic hooks all over the kernel.

Selecting this option will optimize the kernel for use on sn2 based
systems, but the resulting kernel binary will not run on other
types of ia64 systems. If you have an SGI Altix system, it's safe
to select this option. If in doubt, select ia64 generic support
instead.

* PIC AS DEVICE ZERO
* ------------------
*
* PIC handles PCI/X busses. PCI/X requires that the 'bridge' (i.e. PIC)
* be designated as 'device 0'. That is a departure from earlier SGI
* PCI bridges. Because of that we use config space 1 to access the
* config space of the first actual PCI device on the bus.
* Here's what the PIC manual says:
*
* The current PCI-X bus specification now defines that the parent
* hosts bus bridge (PIC for example) must be device 0 on bus 0. PIC
* reduced the total number of devices from 8 to 4 and removed the
* device registers and windows, now only supporting devices 0,1,2, and
* 3. PIC did leave all 8 configuration space windows. The reason was
* there was nothing to gain by removing them. Here in lies the problem.
* The device numbering we do using 0 through 3 is unrelated to the device
* numbering which PCI-X requires in configuration space. In the past we
* correlated Configs pace and our device space 0 <-> 0, 1 <-> 1, etc.
* PCI-X requires we start a 1, not 0 and currently the PX brick
* does associate our:
*
* device 0 with configuration space window 1,
* device 1 with configuration space window 2,
* device 2 with configuration space window 3,
* device 3 with configuration space window 4.
*
* The net effect is that all config space access are off-by-one with
* relation to other per-slot accesses on the PIC.
* Here is a table that shows some of that:
*
* Internal Slot#
* |
* | 0 1 2 3
* ----------|---------------------------------------
* config | 0x21000 0x22000 0x23000 0x24000

* even rrb | 0[0] n/a 1[0] n/a [] == implied even/odd

* CPUID - a number in range of 0..NR_CPUS-1 that uniquely identifies

* the boot cpu is 0.
* smp_processor_id() returns the cpuid of the current cpu.
*
* CPU_PHYSICAL_ID (also known as HARD_PROCESSOR_ID)
* This is the same as 31:24 of the processor LID register
* hard_smp_processor_id()- cpu_physical_id of current processor
* cpu_physical_id(cpuid) - convert a <cpuid> to a <physical_cpuid>
* cpu_logical_id(phy_id) - convert a <physical_cpuid> to a <cpuid>
* * not real efficient - don't use in perf critical code
*
* SLICE - a number in the range of 0 - 3 (typically) that represents the
* cpu number on a brick.
*
* SUBNODE - (almost obsolete) the number of the FSB that a cpu is
* connected to. This is also the same as the PI number. Usually 0 or 1.
*
* NOTE!!!: the value of the bits in the cpu physical id (SAPICid or LID) of a cpu has no
* significance. The SAPIC id (LID) is a 16-bit cookie that has meaning only to the PROM.
*
*
* The macros convert between cpu physical ids & slice/nasid/cnodeid.

* ----- ----- ----- ----- CPU
* | 0 | | 1 | | 0 | | 1 | SLICE
