The only sporadically used CIO_DEBUG messages are replaced by ordinary CIO_MSG_EVENT messages. The CIO_MSG_EVENT messages debug levels are consolidated. Signed-off-by: Michael Ernst <mernst@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

Introduce an ->isc field in the subchannel to store the desired interruption subclass, since sch->schib.pmcw.isc may be overwritten by the hardware on stsch() after machine checks. Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

Most noteable part of this commit is the new local header file entry.h which contains all the function declarations of functions that get only called from asm code or are arch internal. That way we can avoid extern declarations in C files. This is more or less the same that was done for sparc64.

Some fields may be !0 only for I/O subchannels. Add some checks where required. Also adapt cio_enable_subchannel() to make the caller specify the intparm, which makes it more generic. Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

From: Cornelia Huck <cornelia.huck@de.ibm.com> Change the adapter interrupt interface in order to allow multiple adapter interrupt handlers to be registered.

Introduce a private pointer in struct subchannel to store per-subchannel type data (cannot use dev->priv since this is already used for something else). Create a new header io_sch.h for I/O subchannel specific structures and instructions.

Add a new attribute to the channel-path sysfs directory through which channel-path configure operations can be triggered. Also listen for hardware events requesting channel-path configure operations and process them accordingly.

Add a reg_mutex to prevent unregistering a subchannel before it has been registered. Since 2.6.17, we've seen oopses in kslowcrw when a device is found to be not operational during sense id when doing initial device recognition; it is not clear yet why that particular problem was not (yet) observed with earlier kernels...

This patch introduces a struct subchannel_id containing the subchannel number (formerly referred to as "irq") and switches code formerly relying on the subchannel number over to it. While we're touching inline assemblies anyway, make sure they have correct memory constraints.

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!
