* ib_wq is added, which is used as the common workqueue for infiniband
instead of the system workqueue. All system workqueue usages
including flush_scheduled_work() callers are converted to use and
flush ib_wq.
* cancel_delayed_work() + flush_scheduled_work() converted to
cancel_delayed_work_sync().
* qib_wq is removed and ib_wq is used instead.
This is to prepare for deprecation of flush_scheduled_work().

Add check when setting configured contexts that the value does not
exceed the number of contexts allocated for the card. If the value
exceeds the already allocated count, set it to what is already
allocated.

If CONFIG_PCI_MSI is not set, and a QLE7140 is present, the pointer
"dd" is uninitialized.

Up to now, we have set the number of available user contexts based on
the number of hardware contexts which is set according to the number
of available CPUs. This was fine since most CPUs had a power of two
number of cores and the chip supported 4, 8, or 16 user contexts. Now
that some systems have 12 cores, the default isn't optimal and should
be set to 12 even though 16 hardware contexts need to be enabled.

If qib_init() fails, the driver fails to free memory, unregister
device files, and unregister with the PCIe framework. The driver will
unload without error but a subsequent driver load will cause the
system to panic. This was found by changing the 7220 code to load the
serdes microcode separately and not installing the microcode file.

Workqueues aren't exactly equivalent to tasklets since the callback
function may be called from multiple CPUs before the callback returns.
This causes completion notification callbacks to have MT bugs since
they weren't expecting this behavior. The fix is to use a single
threaded work queue.

The eager buffers are not being cleared before being mmapped into a
new user address space. This is a potential security risk and should
be fixed. Note that the eager header queue is already being cleared.

Don't set write combining via PAT on the VL15 buffers to avoid a rare
problem with unaligned writes from interrupt-flushed store buffers.

This patch fixes a compile error saying qib_init_iba6120_funcs() is
undefined when CONFIG_PCI_MSI is not defined. Thanks to Randy Dunlap
<randy.dunlap@oracle.com> for finding this and suggesting the fix.
