Add modalias attribute support for the almost forgotten now EISA bus and
(at least some) EISA-aware modules.
The modalias entry looks like (for an 3c509 NIC):
eisa:sTCM5093
and the in-module alias like:
eisa:sTCM5093*
The patch moves struct eisa_device_id declaration from include/linux/eisa.h
to include/linux/mod_devicetable.h (so that the former now #includes the
latter), adds proper MODULE_DEVICE_TABLE(eisa, ...) statements for all
drivers with EISA IDs I found (some drivers already have that DEVICE_TABLE
declared), and adds recognision of __mod_eisa_device_table to
scripts/mod/file2alias.c so that proper modules.alias will be generated.
There's no support for /lib/modules/$kver/modules.eisamap, as it's not used
by any existing tools, and because with in-kernel modalias mechanism those
maps are obsolete anyway.
The rationale for this patch is:
a) to make EISA bus to act as other busses with modalias
support, to unify driver loading
b) to foget about EISA finally - with this patch, kernel
(who still supports EISA) will be the only one who knows
how to choose the necessary drivers for this bus ;)

Small driver suspend() fixes in preparation for the PRETHAW events:
- Only compare message events for equality against PM_EVENT_* codes;
not against integers, or using greater/less-than comparisons.
(PM_EVENT_* should really become a __bitwise thing.)
- Explicitly test for SUSPEND events (rather than not-something-else)
before suspending devices.
- Removes more of the confusion between a pm_message_t (wraps event code)
and a "state" ... suspend() originally took a target system state.
These updates are correct and appropriate even without new PM_EVENT codes.

This started as a PCI reference fixup but to do that I need to build it,
to build it I need to fix it and its full of 32bitisms and uglies.
It has been resurrected, I'm not sure if this is a thank you for the
work on the license stuff or punishment for some unknown misdeed however
8). I've also fixed a memory scribble in the init code.
One oddity - the changes from HZ * to constants are deliberate. Whoever
originally wrote the code (or cleaned it up) used HZ for a cycle timing
loop even though is not HZ related. I've put it back to the counts used
in the old days when the driver was most used.

Received from Mark Salyzyn:
Until the system is stabilized, I am suggesting the enclosed
modification to prevent the driver from tickling the panic. Once sysfs
and friends are stabilized, the patch may be backed out. We have yet to
evaluate if we really want to relinquish existing Scsi Devices in any
case, holding on to them as configuration of arrays comes and goes makes
some sense as well. As a result, we have opted to pull the lines rather
than comment them in legacy.

Received from Mark Salyzyn:
The only real difference between the rkt and rx platform modules is the
offset of the message registers. This patch recognizes this similarity
and simplifies the driver to reduce it's code footprint and to improve
maintainability by reducing the code duplication.
Visibly, the 'rkt.c' portion of this patch looks more complicated than
it really is. View it as retaining the rkt-only specifics of the
interface.

Received from Mark Salyzyn:
I am placing this functionality into an insmod parameter. Normally the physical
components are exported to sg, and are blocked from showing up in sd.
Note that the pass-through I/O path via the driver through the Firmware to the
physical disks is not an optimized path, the card is designed for Hardware
RAID, elevator sorting and caching. This should not be used as a means for
utilizing the aacraid based controllers as a generic scsi/SATA/SAS controller,
performance should suck by a few percentage points, any RAID meta-data on the
drives will confuse the controller about who owns the drives and there is a
high risk of destroying content in both directions. Unreliable and for
experimentation or strange controlled circumstances only.

For cards that don't support LVD, checking the SBLKCTL register to

ChangeLog:
- add 'vpd_use_hostno' parameter to allow simulated hosts
to see the same set of targets (and luns). For testing
multipath software.
- add 'fake_rw' parameter to ignore the data in READ and
WRITE commands
- add support for log subpages (new in SPC-4)
- yield appropriate block descriptor for MODE SENSE
commands (only for pdt=0 (i.e. disks))
- REQUEST SENSE response no longer shows the stopped

Fix a buglet; the errata check below this code is assuming the value in
the sstatus variable is what was pulled out of the SCR_STATUS register.
However, the status checks in the timeout loop clobber everything
but the first 4 bits of sstatus, so the errata checks are invalid.
This patch changes it to not clobber SStatus.

Spotted by: Dan Aloni <da-xx@monatomic.org>
The problem is there's inconsistent locking semantic usage of
scsi_alloc_target(). Two callers assume the target comes back with
reference unincremented and the third assumes its incremented. Fix by
always making the reference incremented on return. Also fix path in
target alloc that could consistently increment the parent lock.
Finally document scsi_alloc_target() so its callers know what the
expectations are.

callback
This patch adds the following functionality to the FC transport:
- dev_loss_tmo LLDD callback :
Called to essentially confirm the deletion of an rport. Thus, it is
called whenever the dev_loss_tmo fires, or when the rport is deleted
due to other circumstances (module unload, etc). It is expected that
the callback will initiate the termination of any outstanding i/o on
the rport.
- fast_io_fail_tmo and LLD callback:
There are some cases where it may take a long while to truly determine
device loss, but the system is in a multipathing configuration that if
the i/o was failed quickly (faster than dev_loss_tmo), it could be
redirected to a different path and completed sooner.
Many thanks to Mike Reed who cleaned up the initial RFC in support
of this post.

events
This patch formally adds support for the posting of FC events via netlink.
It is a followup to the original RFC at:
http://marc.theaimsgroup.com/?l=linux-scsi&m=114530667923464&w=2
and the initial posting at:
http://marc.theaimsgroup.com/?l=linux-scsi&m=115507374832500&w=2
The patch has been updated to optimize the send path, per the discussions
in the initial posting.
Per discussions at the Storage Summit and at OLS, we are to use netlink for
async events from transports. Also per discussions, to avoid a netlink
protocol per transport, I've create a single NETLINK_SCSITRANSPORT protocol,
which can then be used by all transports.
This patch:
- Creates new files scsi_netlink.c and scsi_netlink.h, which contains the
single and shared definitions for the SCSI Transport. It is tied into the
base SCSI subsystem intialization.
Contains a single interface routine, scsi_send_transport_event(), for a
transport to send an event (via multicast to a protocol specific group).
- Creates a new scsi_netlink_fc.h file, which contains the FC netlink event
messages
- Adds 3 new routines to the fc transport:
fc_get_event_number() - to get a FC event #
fc_host_post_event() - to send a simple FC event (32 bits of data)
fc_host_post_vendor_event() - to send a Vendor unique event, with
arbitrary amounts of data.
Note: the separation of event number allows for a LLD to send a standard
event, followed by vendor-specific data for the event.
Note: This patch assumes 2 prior fc transport patches have been installed:
http://marc.theaimsgroup.com/?l=linux-scsi&m=115555807316329&w=2
http://marc.theaimsgroup.com/?l=linux-scsi&m=115581614930261&w=2
Sorry - next time I'll do something like making these individual
patches of the same posting when I know they'll be posted closely
together.
