The patch titled
genirq: cleanup: merge irq_affinity[] into irq_desc[]
has been removed from the -mm tree. Its filename is
genirq-cleanup-merge-irq_affinity-into-irq_desc.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: genirq: cleanup: merge irq_affinity[] into irq_desc[]
From: Ingo Molnar <mingo@xxxxxxx>
Consolidation: remove the irq_affinity[NR_IRQS] array and move it into the
irq_desc[NR_IRQS].affinity field.
[akpm@xxxxxxxx: sparc64 build fix]
