Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+ *
+ * 11/07/96: rewritten interrupt handling, irq lists are exists now only for
+ *           this sources where it makes sense (VERTB/PORTS/EXTER) and you must
+ *           be careful that dev_id for this sources is unique since this the
+ *           only possibility to distinguish between different handlers for
+ *           free_irq. irq lists also have different irq flags:
+ *           - IRQ_FLG_FAST: handler is inserted at top of list (after other
+ *                           fast handlers)
+ *           - IRQ_FLG_SLOW: handler is inserted at bottom of list and before
+ *                           they're executed irq level is set to the previous
+ *                           one, but handlers don't need to be reentrant, if
+ *                           reentrance occurred, slow handlers will be just
+ *                           called again.
+ *           The whole interrupt handling for CIAs is moved to cia.c
+ *           /Roman Zippel
+ *
+ * 07/08/99: rewamp of the interrupt handling - we now have two types of
+ *           interrupts, normal and fast handlers, fast handlers being
+ *           marked with SA_INTERRUPT and runs with all other interrupts
+ *           disabled. Normal interrupts disable their own source but
+ *           run with all other interrupt sources enabled.
+ *           PORTS and EXTER interrupts are always shared even if the
+ *           drivers do not explicitly mark this when calling
+ *           request_irq which they really should do.
+ *           This is similar to the way interrupts are handled on all
+ *           other architectures and makes a ton of sense besides
+ *           having the advantage of making it easier to share
+ *           drivers.
