There were many places that my previous spatch didn't find,
as pointed out by yuan linyu in various patches.
The following spatch found many more and also removes the
now unnecessary casts:

Apply it to the tree (with one manual fixup to keep the
comment in vxlan.c, which spatch removed.)

The ->seq_start_next callback only ever had one implementation,
so call the function directly and drop the callback.

The uses of "rcu_assign_pointer()" are NULLing out the pointers.
According to RCU_INIT_POINTER()'s block comment:
"1. This use of RCU_INIT_POINTER() is NULLing out the pointer"
it is better to use it instead of rcu_assign_pointer() because it has a
smaller overhead.
The following Coccinelle semantic patch was used:

The module.h header was implicitly present everywhere, so files
with no explicit include of the module infrastructure would build
anyway. We are now removing the implicit include, and so we need
to call out the module.h file that we need explicitly.

target.
Problem:
From initaitor machine, when queried role of target (other end of connection),
it is "initiator", hence SCSI-ml doesn't send any LUN Inquiry commands.
Fix:
If there is a registered target for FC_TYPE_FCP, extend lport's params
(capability) to be target as well, By default lport params are
INITIATOR only. Having this fix, caused initiator to send SCSI LUN
inquiry command to target.

When an SCST provider is registered, it needs to know what
local ports are available for configuration as targets.
Add a notifier chain that is invoked when any local port
that is added or deleted.
Maintain a global list of local ports and add an
interator function that calls a given function for
every existing local port. This is used when first
loading a provider.

Allow FC-4 provider modules to hook into libfc, mostly for targets.
This should allow any FC-4 module to handle PRLI requests and maintain
process-association states.
Each provider registers its ops with libfc and then will be called for
any incoming PRLI for that FC-4 type on any instance. The provider
can decide whether to handle that particular instance using any method
it likes, such as ACLs or other configuration information.
A count is kept of the number of successful PRLIs from the remote port.
Providers are called back with an implicit PRLO when the remote port
is about to be deleted or has been reset.
fc_lport_recv_req() now sends incoming FC-4 requests to FC-4 providers,
and there is a built-in provider always registered for handling
incoming ELS requests.
The call to provider recv() routines uses rcu_read_lock()
so that providers aren't removed during the call. That lock is very
cheap and shouldn't affect any performance on ELS requests.
Providers can rely on the RCU lock to protect a session lookup as well.

Add functions to fill in an FC header given a request header.
These reduces code lines in fc_lport and fc_rport and works
without an exchange/sequence assigned.
fc_fill_reply_hdr() fills a header for a final reply frame.
fc_fill_hdr() which is similar but allows specifying the
f_ctl parameter.
Add defines for F_CTL values FC_FCTL_REQ and FC_FCTL_RESP.
These can be used for most request and response sequences.
v2 of patch adds a line to copy the frame encapsulation
info from the received frame.

This patch makes a variety of cleanup changes to all libfc files.
This patch adds kernel-doc headers to all functions lacking them
and attempts to better format existing headers. It also add kernel-doc
headers to structures.
This patch ensures that the current naming conventions for local ports,
remote ports and remote port private data is upheld in the following
manner.
struct instance (i.e. variable name)
--------------------------------------------------
fc_lport lport
fc_rport rport
fc_rport_libfc_priv rpriv
fc_rport_priv rdata
I also renamed dns_rp and ptp_rp to dns_rdata and ptp_rdata
respectively.
I used emacs 'indent-region' and 'tabify' on all libfc files
to correct spacing alignments.
I feel sorry for anyone attempting to review this patch.

When handling the multi-frame responses of fc pass-thru requests,
a code segment similar to fc_fcp_recv_data (routine to receive
inbound SCSI data) is used in the response handler. This patch
is to add a routine, called fc_copy_buffer_to_sglist(), to handle
the common function of copying data from a buffer to a scatter-
gather list in order to avoid code duplication.

These routines are for the libfc kernel module and should be in
the libfc .c file.
Moving the libfc __init routine into fc_libfc.c caused the creation
of the fc_setup_fcp() and fc_destroy_fcp() routines so that
scsi_pkt_cachep was not exposed outside of fc_fcp.c.

include/scsi/libfc.h is currently loaded with common code
shared between libfc's sub-modules as well as shared between
libfc and fcoe. Previous patches attempted to move out
non-common code. This patch creates two files for common
libfc routines that will not be shared with fcoe, fnic or
any other LLDs.
