[Patch:002/011] Configureable NODES_SHIFT (for ia64)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is for ia64.
The number of nodes can be already configured in generic ia64 and SN2 config.
But, NODES_SHIFT is defined for DIG64 and HP'S machine too.
So, I changed that all platform can be configured by CONFIG_NODES_SHIFT.
It would be simpler.
