The patch titled
m68knommu: fix fec driver interrupt races
has been removed from the -mm tree. Its filename was
m68knommu-fix-fec-driver-interrupt-races.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: m68knommu: fix fec driver interrupt races
From: Greg Ungerer <gerg@xxxxxxxxxxxx>
The FEC driver has a common interrupt handler for all interrupt event types.
It is raised on a number of distinct interrupt vectors. This handler can't be
re-entered while processing an interrupt, so make sure all requested vectors
are flagged as IRQF_DISABLED.
