Remove the file name from the comment at top of many files. In most cases the file name was wrong anyway, so it's rather pointless. Also unify the IBM copyright statement. We did have a lot of sightly different statements and wanted to change them one after another whenever a file gets touched. However that never happened. Instead people start to take the old/"wrong" statements to use as a template for new files. So unify all of them in one go. Signed-off-by: NHeiko Carstens <heiko.carstens@de.ibm.com>

After changing all internal I/O functions to use the newly introduced ccw request infrastructure, retries are handled automatically after a clear operation. Therefore remove the internal retry flag and associated code. Signed-off-by: NPeter Oberparleiter <peter.oberparleiter@de.ibm.com> Signed-off-by: NMartin Schwidefsky <schwidefsky@de.ibm.com>

There is the chance that we get condition code 0 for a stsch but the resulting schib is not vaild. In the current code there are 2 cases: * we do a check for validity of the schib after stsch, but at this time we have already stored the invaild schib in the subchannel structure. This may lead to problems. * we don't do a check for validity, which is not that good either. The patch addresses both issues by introducing the stsch wrapper cio_update_schib which performs stsch on a local schib. This schib is only written back to the subchannel if it's valid. side note: For some functions (chp_events) the return codes are different now (-ENXIO vs -ENODEV) but this shouldn't do harm since the caller doesn't check for _specific_ errors.

Currently, we don't do much on no path or no device situations during normal user I/O, since we rely on reports regarding those events by the machine. If we trigger a path verification to bring our device state up-to-date, we (a) may recover from path failures earlier and (b) better handle situations where the hardware/hypervisor doesn't give us enough notifications.

1. Multipath devices for which SetPGID is not supported are not handled well. Use NOP ccws for path verification (sans path grouping) when SetPGID is not supported. 2. Check for PGIDs already set with SensePGID on _all_ paths (not just the first one) and try to find a common one. Moan if no common PGID can be found (and use NOP verification). If no PGIDs have been set, use the css global PGID (as before). (Rationale: SetPGID will get a command reject if the PGID it tries to set does not match the already set PGID.) 3. Immediately before reboot, issue RESET CHANNEL PATH (rcp) on all chpids. This will remove the old PGIDs. rcp will generate solicited CRWs which can be savely ignored by the machine check handler (all other actions create unsolicited CRWs).

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!
