qla2xxx first calls request_irq() and then does the setup of the queue
entry data needed in the interrupt handlers in when using MSI-X. This
could lead to a NULL pointer dereference when an IRQ fires between the
request_irq() call and the assignment of the qentry data structure to
the rsp->msix field. A possible case for such a race would be in the
kdump case when the HBA's IRQs are still enabled but the driver is
undergoing a new initialisation and thus is not aware of already
activated IRQs in the HBA.

There was an issue reported by Lucz Geza on Dell Perc 6i. As per issue
reported, megaraid_sas driver goes into an infinite error reporting loop
as soon as there is a change in the status of one of the
arrays (degrade, resync online etc ).  Below are the error logs reported
continuously-

Jun 25 08:49:30 ns8 kernel: [  757.757017] megaraid_sas 0000:02:00.0: DCMD failed/not supported by firmware: megasas_get_pd_list 4115

This issue is very much specific to controllers which do not support
DCMD- MR_DCMD_PD_LIST_QUERY.  In case of any hotplugging/rescanning of
drives, AEN thread will be scheduled by driver and fire DCMD-
MR_DCMD_PD_LIST_QUERY and if this DCMD is failed then driver will fail
this event processing and will not go ahead for further events. This
will cause infinite loop of same event getting retried infinitely and
causing above mentioned logs.

Fix for this problem is: not to fire DCMD MR_DCMD_PD_LIST_QUERY for
controllers which do not support it and send DCMD SUCCESS status to AEN
function so that it can go ahead with other event processing.

In the receive path libfc extracts a cpu number from the ox_id in the
fiber channel header and uses that to do a per_cpu_ptr conversion.  If,
for some reason, a frame is received with an invalid ox_id, per_cpu_ptr
will return an invalid pointer and the libfc receive path will panic the
system trying to use it.

I'm currently looking at such a case, and I don't yet know why a cpu
number > nr_cpu_ids is appearing in an exchange id.  But adding a sanity
check in libfc prevents a system panic, and seems like good idea when
dealing with frames coming in from the network.

The driver creates its own per-CPU threads which are updated based on
CPU hotplug events. It is also possible to use kworkers and remove some
of the kthread infrastrucure.

The code checked ->thread to decide if there is an active per-CPU
thread. By using the kworker infrastructure this is no longer
possible (or required). The thread pointer is saved in `kthread' instead
of `thread' so anything trying to use thread is caught by the
compiler. Currently only the bnx2fc driver is using struct fcoe_percpu_s
and the kthread member.

After a CPU went offline, we may still enqueue items on the "offline"
CPU. This isn't much of a problem. The work will be done on a random
CPU. The allocated crc_eof_page page won't be cleaned up. It is probably
expected that the CPU comes up at some point so it should not be a
problem. The crc_eof_page memory is released of course once the module
is removed.

This patch was only compile-tested due to -ENODEV.
