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-core.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: genirq: add chip->eoi(), fastack -> fasteoi
From: Ingo Molnar <mingo@xxxxxxx>
Clean up the fastack concept by turning it into fasteoi and introducing the
->eoi() method for chips.
This also allows the cleanup of an i386 EOI quirk - now the quirk is
cleanly separated from the pure ACK implementation.
