From 8795dba6a479913957c9c6e761abffabcc19d4a9 Mon Sep 17 00:00:00 2001
From: Martin Dalecki <dalecki@evision-ventures.com>

Subject: [PATCH] [PATCH] 2.5.19 blk.h and more about the ugly kids.
- Remove DEVICE_INTR and associated code from floppy driver.
- Savlage s390 xpram code from kernel version dependant compilation disease.
- Eliminate SET_INTR code from the places where it was used.
- Eliminate bogous support for multiple sbpcd controllers. The driver didn't
even compile right now before we could think about further supporting it at
all we have to get rid of this hack first.
Don't call invalidate_buffers in the release method there.
Why should it be necessary?
- Resurrect sonycd535 compilation.
- Let CURRENT request macro use the same primitive at the remaining QUEUE macro
in blk.h, which is still not quite right, but first things first :-).
