The patch titled
genirq: add chip->eoi(), fastack -> fasteoi
has been removed from the -mm tree. Its filename is
genirq-add-chip-eoi-fastack-fasteoi-x86.patch
This patch was dropped because it was folded into genirq-convert-the-i386-architecture-to-irq-chips.patch
------------------------------------------------------
Subject: genirq: add chip->eoi(), fastack -> fasteoi
From: Ingo Molnar <mingo@xxxxxxx>
The patch enables the fasteoi handler for i386 level-triggered IO-APIC irqs.
