[PATCH 1/6] powerpc: Make NR_IRQS a CONFIG option

2009-10-13 Thread Michael Ellerman
The irq_desc array consumes quite a lot of space, and for systems that don't need or can't have 512 irqs it's just wasted space. The first 16 are reserved for ISA, so the minimum of 32 is really 16 - and no one has asked for more than 512 so leave that as the maximum. Signed-off-by: Michael Eller
