Thomas noticed that a lock marked with lockdep_set_novalidate_class() will still trigger warnings for IRQ inversions. Cure this by skipping those when marking irq state. Reported-and-tested-by:

The non-debug variant of mutex_destroy is a no-op, currently implemented as a macro which does nothing. This approach fails to check the type of the parameter, so an error would only show when debugging gets enabled. Using an inline function instead, offers type checking for earlier bug catching.

Commits 71c29bd5 ("IB/uverbs: Add devnode method to set path/mode") and c3af0980 ("IB: Add devnode methods to cm_class and umad_class") added devnode methods that set the mode. However, these methods don't check for a NULL mode, and so we get a crash when unloading modules because devtmpfs_delete_node() calls device_get_devnode() with mode == NULL. Add the missing checks.

The recently modified nand buswitth configuration is not aligned with board reality: the double footprint on boards is always populated with 8bits buswidth nand flashes. So we have to consider that without particular configuration the 8bits buswidth is selected by default. Moreover, the previous logic was always using !board_have_nand_8bit(), we change it to a simpler: board_have_nand_16bit(). Signed-off-by:

The distinction between scic_sds_ scic_ and sci_ are no longer relevant so just unify the prefixes on sci_. The distinction between isci_ and sci_ is historically significant, and useful for comparing the old 'core' to the current Linux driver. 'sci_' represents the former core as well as the routines that are closer to the hardware and protocol than their 'isci_' brethren. sci == sas controller interface. Also unwind the 'sds1' out of the parameter structs. Reported-by:

Remove the distinction between these two implementations and unify on isci_port (local instances named iport). The duplicate '->owning_port' and '->isci_port' in both isci_phy and isci_remote_device will be fixed in a later patch... this is just the straightforward rename/unification. Reported-by:

Commit 0815632 "isci: unify remote_device stop_handlers" introduced the possibility that not all requests get terminated if we reach the request_count. Now that we properly reference count devices we don't need this self-defense and can do the straightforward scan of all active requests. Reported-by:

the dma_pool interface is optimized for object_size << page_size which is not the case with isci_request objects and the dma_pool routines show up in the top of the profile.

The tci_pool tracks our outstanding command slots which are also the 'index' portion of our tags. Grabbing the tag early in ->lldd_execute_task let's us drop the isci_host_can_queue() and ->was_tag_assigned_by_user infrastructure. ->was_tag_assigned_by_user required the task context to be duplicated in request-local buffer. With the tci established early we can build the task_context directly into its final location and skip a memcpy. With the task context buffer at a known address at request construction we have the opportunity/obligation to also fix sgl handling. This rework feels like it belongs in another patch but the sgl handling and task_context are too intertwined. 1/ fix the 'ab' pair embedded in the task context to point to the 'cd' pair in the task context (previously we were prematurely linking to the staging buffer). 2/ fix the broken iteration of pio sgls that assumes all sgls are relative to the request, and does a dangerous looking reverse lookup of physical address to virtual address.
