[PATCH 4/8] Staging: hv: vmbus: Do not enable auto eoi

From: "K. Y. Srinivasan" <kys@microsoft.com>
Date: 2011-08-15 21:53:34
Also in: lkml
Subsystem: staging subsystem, the rest · Maintainers: Greg Kroah-Hartman, Linus Torvalds

The standard interrupt handling in Linux issues an eoi when the
interrupt handling is done. So, setup the vmbus interrupt without
enabling auto eoi.
