has been removed from the -mm tree. Its filename is
genirq-cleanup-merge-irq_dir-smp_affinity_entry-into-irq_desc.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: genirq: cleanup: merge irq_dir[], smp_affinity_entry[] into irq_desc[]
From: Ingo Molnar <mingo@xxxxxxx>
Consolidation: remove the irq_dir[NR_IRQS] and the smp_affinity_entry[NR_IRQS]
arrays and move them into the irq_desc[] array.
