[PATCH] genirq: irq: generalize the check for HARDIRQ_BITS
This patch adds support for systems that cannot receive every interrupt on a
single cpu simultaneously, in the check to see if we have enough HARDIRQ_BITS.
MAX_HARDIRQS_PER_CPU becomes the count of the maximum number of hardare
generated interrupts per cpu.
On architectures that support per cpu interrupt delivery this can be a
significant space savings and scalability bonus.
This patch adds support for systems that cannot receive every interrupt on
