The patch titled
8390: Split 8390 support into a pausing and a non pausing driver core
has been removed from the -mm tree. Its filename was
8390-split-8390-support-into-a-pausing-and-a-non-pausing-driver-core.patch
This patch was dropped because of fed upness
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: 8390: Split 8390 support into a pausing and a non pausing driver core
From: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx>
Only a few ISA controllers need the pausing version of the 8390 core
while PCMCIA, later ISA and PCI do not. More importantly the ISA delays
can break non ISA boxes so we must use a different build of 8390.c for
the two sets of controllers.
No changes since last time as all the points of concerns raised proved to
be invalid
[randy.dunlap@xxxxxxxxxx: ne2 (MCA) needs both 8390.o and 8390p.o functions]
