has been removed from the -mm tree. Its filename is
lockdep-annotate-8390c-disable_irq-2.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: lockdep: annotate 8390.c disable_irq(), #2
From: Arjan van de Ven <arjan@xxxxxxxxxxxxxxx>
The ne2000 drivers use disable_irq as a poor mans locking construct; make
sure lockdep knows about these.
NOTE NOTE: the ne2000 driver calls these *from interrupt context*. That's
a new situation that needs to be analyzed for correctness still; it feels
really wrong to me (but then again so does disable_irq() tricks in general)
