mainline/server kernel NumaChip support enablement...

[Daniel J Blueman]

Dear Ubuntu kernel team,

Support for Numascale's commodity large-SMP adapters [1] made it into 
3.2-rc1. It would be very helpful if you were to enable 
CONFIG_X86_NUMACHIP on the mainline builds [2], and later for the server 
kernels. With this enablement, it'll be easy to boot large (>168 cores) 
systems using newer Ubuntu kernels.

Since the APIC probe function (to select the NumaChip APIC handler) 
looks at one string in an ACPI table, the boot-time overhead should be 
only around a couple of hundred instructions, and there is no run-time 
overhead.

Let me know if you need more information.

Many thanks,
   Daniel
