fcoe selects libfc and requires SCSI and PCI (the SCSI requirement is implicitly covered by an enclosing if). Fix them both up so they cannot be configured in an invalid state: make LIBFC select SCSI_FC_ATTRS and make FCOE depend on PCI and select LIBFC.

cxgb3i requires the cxgb3 net driver, so it selects it. However, cxgb3 has dependencies which the select cannot see. Fix this by separating out the cxgb3 dependencies into a separate hidden config option (CONFIG_CHELSIO_T3_DEPENDS) and make both cxgb3 and cxgb3i depend on it.

Now that (almost) all host drivers have been fixed not to abuse ide_lock and core code usage of ide_lock has been sanitized we may safely replace ide_lock by per-hwgroup locks. This patch is partially based on earlier patch from Ravikiran G Thirumalai. While at it: - don't use deprecated HWIF() and HWGROUP() macros - update locking documentation in ide.h v2: Add missing spin_lock_init(&hwgroup->lock). (Noticed by Elias Oltmanns) Cc: Vaibhav V.

Pre-emptively terminate i/o on the rport if dev_loss_tmo has fired. The desire is to terminate everything, so that the i/o is cleaned up prior to the sdev's being unblocked, thus any outstanding timeouts/aborts are avoided. Also, we do this early enough such that the rport's port_id field is still valid. FCOE libFC code needs this info to find the i/o's to terminate.

The base request and response queues are created by default. 3. Additional request and response queues are created at the time of vport creation. If queue resources are exhausted during vport creation, newly created vports use the default queue. 4. Requests are sent to the request queue that the vport was assigned in the beginning. 5. Responses are completed on the response queue with which the request queue is associated with.

libFC is composed of 4 blocks supported by an exchange manager and a framing library. The upper 4 layers are fc_lport, fc_disc, fc_rport and fc_fcp. A LLD that uses libfc could choose to either use libfc's block, or using the transport template defined in libfc.h, override one or more blocks with its own implementation. The EM (Exchange Manager) manages exhcanges/sequences for all commands- ELS, CT and FCP. The framing library frames ELS and CT commands. The fc_lport block manages the library's representation of the host's FC enabled ports. The fc_disc block manages discovery of targets as well as handling changes that occur in the FC fabric (via. RSCN events). The fc_rport block manages the library's representation of other entities in the FC fabric. Currently the library uses this block for targets, its peer when in point-to-point mode and the directory server, but can be extended for other entities if needed. The fc_fcp block interacts with the scsi-ml and handles all I/O.

The ibmvscsi driver currently has a bug in it which can result in it using up all its event structs for commands. If something results in all those commands timing out, we won't have any resources left to send aborts or resets. This results in escalating to a host reset in order to recover, which is a bit heavy handed. This fixes it by reducing can_queue by two in order to have resources to do EH. It also changes the max_requests module parameter so that it is not writable at runtime, since the code really does not handle it changing at runtime.

Per the recent discussions at the Linux Plumbers Conference, when enabling MSI or MSI-X, generate a test interrupt to verify the interrupt routing is working properly. If the test interrupt fails, fall back to MSI first, and if that fails as well, to INTx. If the interrupt test fails with INTx, log an error and fail the PCI probe. Also changed the use of spin_(lock|unlock) to the _irq(save|restore) variants in the interrupt handlers because with multi-message MSI-X, both interrupt handlers can now run in parallel.
