This makes sure that when a driver calls the ethtool's
get/set_settings() callback of another driver, the data passed to it
is clean. This guarantees that speed_hi will be zeroed correctly if
the called callback doesn't explicitely set it: we are sure we don't
get a corrupted speed from the underlying driver. We also take care of
setting the cmd field appropriately (ETHTOOL_GSET/SSET).
This applies to dev_ethtool_get_settings(), which now makes sure it
sets up that ethtool command parameter correctly before passing it to
drivers. This also means that whoever calls dev_ethtool_get_settings()
does not have to clean the ethtool command parameter. This function
also becomes an exported symbol instead of an inline.
All drivers visible to make allyesconfig under x86_64 have been
updated.

Stop including <linux/delay.h> in x86 header files which don't
need it. This will let the compiler complain when this header is
not included by source files when it should, so that
contributors can fix the problem before building on other
architectures starts to fail.
Credits go to Geert for the idea.

Disable Interrupt MBX completion will disable the interrupt on
successful completion. Fixed the bug where driver was waiting for
Interrupt to come in for its completion. Now driver will poll for
disable interrupt MBX completion.

Driver does not detect a new CQE (completion queue entry) if a thread receives
the wakup when it is in TASK_RUNNING state. Fix is to set the state to
TASK_INTERRUPTIBLE while holding the fp_work_lock.
Also, Use __set_current_task() since it is now set inside a spinlock with
synchronization.
Two other related optimizations:
1. After we exit the while (!kthread_should_stop()) loop, use
__set_current_state() since synchronization is no longer needed.
2. Remove set_current_state(TASK_RUNNING) after schedule() since it
should always be TASK_RUNNING after schedule().

FW is not able to process mbox command if FW state is failed. This will cause
mbox command to timeout and adapter reset. We have separate function to detect
FW failed state and do adapter reset. So to avoid mbox command timeout, do not
process mbox command in case of FW state failed.

There have been many complaints that an enclosure with subenclosures
isn't attached to by the ses driver. Until now, though, no-one had
been willing to provide access to one.
Subenclosures are added simply by flattening the tree (i.e. all
subenclosure devices show up under the one main device). This may have
consequences if the naming is only unique per subenclosure, but that's a
bug for another day. The tested array had no page 7, so no device
naming at all. It also only had the disk devices on one of its
subenclosures (all the others had power, fans, temperature and various
sensors), so testing of this is fairly rudimentary.
