o always use locking when changing erp_action lists,
o avoid escalation to ERP_ACTION_REOPEN_PORT_FORCED if erp_action is
still in use for ERP_ACTION_REOPEN_PORT

This patch fixes a severe problem with 2.6.13-rc7.
Due to recent SCSI changes it is not possible to add any LUNs to the zfcp
device driver anymore. With registration of remote ports this is fixed.

Fixes module parameter parsing for "device" parameter. The original
module parameter was changed while parsing it. This corrupted the
output in sysfs (/sys/module/zfcp/parameters/device).

Fixes a race between zfcp_fsf_req_dismiss_all and
zfcp_qdio_reqid_check. During adapter shutdown it occurred that a
request was cleaned up twice. First during its normal
completion. Second when dismiss_all was called. The fix is to
serialize access to fsf request list between zfcp_fsf_req_dismiss_all
and zfcp_qdio_reqid_check and delete a fsf request from the list if
its completion is triggered. (Additionally a rwlock was replaced by a
spinlock and fsf_req_cleanup was eliminated.)

Fixes a bug in zfcp_send_els_handler. If D_ID assignments for ports
are changing between initiation of one ELS request and its completion
the wrong port might be accessed in the completion for that ELS
request. Thus a pointer to the port has to be passed for ELS requests
to identify the port structure if required.

Reopen a remote port only if the link-test fails. This avoids that a

Extend the time for adapter initialization: In case of protocol
status HOST_CONNECTION_INITIALIZING for the exchange config data
command do a first retry in 1 second, then double the sleep time for
each following retry until recovery exceeds 2 minutes. The old
behaviour of allowing 6 retries with .5 seconds delay between retries
was insufficient and qdio queues were shut down too erarly.

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!
