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!

* DASD_9336_ERP_EXAMINE

|
* DESCRIPTION
|
|
* Checks only for fatal/no/recover error.
|
|
* A detailed examination of the sense data is done later outside
|
|
* the interrupt handler.
|
|
*
|
|
* The logic is based on the 'IBM 3880 Storage Control Reference' manual
|
|
* 'Chapter 7. 9336 Sense Data'.
|
|
*
|
|
* RETURN VALUES
|
|
* dasd_era_none no error
|
|
* dasd_era_fatal for all fatal (unrecoverable errors)
|
|
* dasd_era_recover for all others.
