7b595756ec sysfs: kill unnecessary attribute->owner
sysfs is now completely out of driver/module lifetime game.  After
deletion, a sysfs node doesn't access anything outside sysfs proper,
so there's no reason to hold onto the attribute owners.  Note that
often the wrong modules were accounted for as owners leading to
accessing removed modules.

This patch kills now unnecessary attribute->owner.  Note that with
this change, userland holding a sysfs node does not prevent the
backing module from being unloaded.

For more info regarding lifetime rule cleanup, please read the
following message.

44c10138fd PCI: Change all drivers to use pci_device->revision
Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.

This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.

In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

Compile tested with make all{yes,mod}config on x86_64 and i386.

6164c8cd13 IB/cm: Send no match if a SIDR REQ does not match a listen
If a SIDR REQ does not match a listen, we should reply with status
value 1 (service ID not supported), rather than dropping through to
the default case of status 2 (rejected by service provider).

Doing this also fixes a bug where the cm_id_priv is removed from the
remote_sidr_table twice.

1d84612649 IB/cm: Include HCA ACK delay in local ACK timeout
The IB CM should include the HCA ACK delay when calculating the local
ACK timeout value to use for RC QPs.  If the HCA ACK delay is large
enough relative to the packet life time, then if it is not taken into
account, the calculated timeout value ends up being too small, which
can result in "retry exceeded" errors.

2aec5c602c IB/sa: Make sure SA queries use default P_Key
MADs sent to the SA should use the the default P_Key (0x7fff/0xffff).
There's no requirement that the default P_Key is stored at index 0 in
the local P_Key table, so add code to the sa_query module to look up
the index of the default P_Key when creating an address handle for the
SA (which is done any time the P_Key table might change), and use this
index for all SA queries.

1b844afe9e IPoIB: Recycle loopback skbs instead of freeing and reallocating
InfiniBand HCAs replicate multicast packets back to the QP that sent
them if that QP is attached to the destination multicast group.  This
means that IPoIB multicasts are often replicated back to the receive
queue of the interface that generated them.  To avoid confusing the
network stack, we drop these duplicates within the IPoIB driver.

However, there's no reason to free the skb that received the duplicate
and then immediately allocate a new skb to post to the receive queue.
We can be more efficient and just repost the same skb.

Due to a HW issue, our current scheme to transition the connection from
streaming to rdma mode is broken on the passive side.  The firmware
and driver now support a new transition scheme for the passive side:

 - driver posts rdma_init_wr (now including the initial receive seqno)
 - driver posts last streaming message via TX_DATA message (MPA start
   response)
 - uP atomically sends the last streaming message and transitions the
   tcb to rdma mode.
 - driver waits for wr_ack indicating the last streaming message was ACKed.

NOTE: This change also bumps the required firmware version to 4.3.
