Greg Kroah-Hartman 6f03979051 Drivers: scsi: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Linus Torvalds bdc0077af5 SCSI misc on 20120724
The most important feature of this patch set is the new async infrastructure
 that makes sure async_synchronize_full() synchronizes all domains and allows
 us to remove all the hacks (like having scsi_complete_async_scans() in the
 device base code) and means that the async infrastructure will "just work" in
 future. The rest is assorted driver updates (aacraid, bnx2fc, virto-scsi,
 megaraid, bfa, lpfc, qla2xxx, qla4xxx) plus a lot of infrastructure work in
 sas and FC.

Robert Love 8d55e507d2 [SCSI] fcoe, bnx2fc, libfcoe: SW FCoE and bnx2fc use FCoE Syfs
This patch has the SW FCoE driver and the bnx2fc
driver make use of the new fcoe_sysfs API added
earlier in this patch series.

After this patch a fcoe_ctlr_device is allocated with
private data in this order.

+------------------+   +------------------+
| fcoe_ctlr_device |   | fcoe_ctlr_device |
+------------------+   +------------------+
| fcoe_ctlr        |   | fcoe_ctlr        |
+------------------+   +------------------+
| fcoe_interface   |   | bnx2fc_interface |
+------------------+   +------------------+

libfcoe also takes part in this new model since it
discovers and manages fcoe_fcf instances. The memory
allocation is different for FCFs. I didn't want to
impact libfcoe's fcoe_fcf processing, so this patch
creates fcoe_fcf_device instances for each discovered
fcoe_fcf. The two are paired using a (void * priv)
member of the fcoe_ctlr_device. This allows libfcoe
to continue maintaining its list of fcoe_fcf instances
and simply attaches and detaches them from existing
or new fcoe_fcf_device instances.

Robert Love fd8f89027d [SCSI] bnx2fc: Allocate fcoe_ctlr with bnx2fc_interface, not as a member
Currently the fcoe_ctlr associated with an interface is allocated
    as a member of struct bnx2fc_interface. This causes problems when
    when later patches attempt to use the new fcoe_sysfs APIs which
    allow us to allocate the bnx2fc_interface as private data to a
    fcoe_ctlr_device instance. The problem is that libfcoe wants to
    be able use pointer math to find a fcoe_ctlr's fcoe_ctlr_device
    as well as finding a fcoe_ctlr_device's assocated fcoe_ctlr. To
    do this we need to allocate the fcoe_ctlr_device, with private
    data for the LLD. The private data will contain the fcoe_ctlr
    and its private data will be the bnx2fc_interface.

    +-------------------+
    | fcoe_ctlr_device  |
    +-------------------+
    | fcoe_ctlr         |
    +-------------------+
    | bnx2fc_interface  |
    +-------------------+

    This prep work will allow us to go from a fcoe_ctlr_device
    instance to its fcoe_ctlr as well as from a fcoe_ctlr to its
    fcoe_ctlr_device once the fcoe_sysfs API is in use (later
    patches in this series).

Bhanu Prakash Gollapudi 013068fa6f [SCSI] bnx2fc: Fix panic caused because of incorrect errror handling in create().
Driver incorrectly calls bnx2fc_interface_cleanup() when bnx2fc_if_create fails
which accesses bad pointer. Handle bnx2fc_if_create failure by directly calling
bnx2fc_net_cleanup.

Bhanu Prakash Gollapudi 0cbf32e168 [SCSI] bnx2fc: Avoid calling bnx2fc_if_destroy with unnecessary locks
It is not required to hold rtnl_lock and bnx2fc_dev_lock when calling
bnx2fc_if_destroy, as the locking is only required to serialize creation and
deletion of fcoe instances. More importantly, this unnecessary locking causes
deadlock as bnx2fc_if_destroy calls fc_remove_host holding rtnl_lock.

Bhanu Prakash Gollapudi 8a5badf1ea [SCSI] bnx2fc: Send solicitation only after vlan discovery is complete
Link up event is generated to the driver even before vlan discovery has
started. Because of this driver can send discovery solicitation on a stale
vlan. Call fcoe_ctlr_link_up() only when the driver is in enabled state, which
implies the vlan discovery is complete before sending solicitation.

Jiri Pirko 4bc71cb983 net: consolidate and fix ethtool_ops->get_settings calling
This patch does several things:
- introduces __ethtool_get_settings which is called from ethtool code and
  from drivers as well. Put ASSERT_RTNL there.
- dev_ethtool_get_settings() is replaced by __ethtool_get_settings()
- changes calling in drivers so rtnl locking is respected. In
  iboe_get_rate was previously ->get_settings() called unlocked. This
  fixes it. Also prb_calc_retire_blk_tmo() in af_packet.c had the same
  problem. Also fixed by calling __dev_get_by_index() instead of
  dev_get_by_index() and holding rtnl_lock for both calls.
- introduces rtnl_lock in bnx2fc_vport_create() and fcoe_vport_create()
  so bnx2fc_if_create() and fcoe_if_create() are called locked as they
  are from other places.
- use __ethtool_get_settings() in bonding code

v2->v3:
	-removed dev_ethtool_get_settings()
	-added ASSERT_RTNL into __ethtool_get_settings()
	-prb_calc_retire_blk_tmo - use __dev_get_by_index() and lock
	 around it and __ethtool_get_settings() call
v1->v2:
        add missing export_symbol
