Refactor version handling logic for ADF_VF2PF_MSGTYPE_COMPAT_VER_REQ
and ADF_VF2PF_MSGTYPE_VERSION_REQ on the PF.
Response messages are now filled only after fully parsing the request,
in a consisted way with the rest of the PFVF codebase.
This patch also fixes a harmless double setting for VERSION in the
response for ADF_VF2PF_MSGTYPE_VERSION_REQ.

Currently, any PF response to a VF request is fully parsed during the
interrupt handling. This way the individual response values are stored
into the accel_dev structure, preventing the caller to access and decode
the full response message itself.
Change this behavior, by letting the API return back the entire message
to the caller, in order to:
- keep correlated code together, that is, the (building of the)
request and the (decoding of the) response;
- avoid polluting the accel_dev data structure with unnecessary and at
times temporary values; only the entire message is stored in a
temporary buffer.

Reorganize the structure of the PFVF code by moving the content of
adf_pf2vf_msg.c and adf_vf2pf_msg.c.
The logic that handles high level messages has been moved to
adf_pfvf_pf_msg.c and adf_pfvf_vf_msg.c.
The implementation of low level communication primitives and the
protocol is now included in adf_pfvf_pf_proto.c and adf_pfvf_vf_proto.c.
In addition, the file adf_pf2vf_msg.h has been renamed in adf_pfvf_msg.h
since it common to PF and VF and the copyright date for the touched
files has been updated.

Refactor the PFVF receive logic so it is common between PF and VF and
make it device specific.
This is in preparation for the introduction of PFVF support in the
qat_4xxx driver since the receive logic differs between QAT GEN2 and

Add the function get_vf2pf_offset() to adf_pfvf_ops to differentiate the
CSRs used for pf2vf and vf2pf.
Offsets may or may not be direction specific depending on QAT
generation. Since in QAT GEN2 the CSR is not direction specific, i.e.
there is a single mailbox register shared for pf2vf and vf2pf, both
get_vf2pf_offset() and get_vf2pf_offset() will return the same offset.
This change is to make the direction explicit, so it is easier to
understand and debug and also in preparation for the introduction of
PFVF support in the qat_4xxx driver since QAT GEN4 devices have a
separate CSR for pf2vf and vf2pf communications.

Add pfvf_ops structure to isolate PFVF related functions inside the
adf_hw_device_data structure.
For GEN2, the structure is populated using one of the two helper
functions, adf_gen2_init_pf_pfvf_ops() or adf_gen2_init_vf_pfvf_ops(),
for the PF and VF driver respectively.
For the DH895XCC PF driver, the structure is populated using
adf_gen2_init_pf_pfvf_ops() but some of the functions are then
overwritten.

Rework __adf_iov_putmsg() to handle retries due to collisions
internally, removing the need for an external retry loop.
The functions __adf_iov_putmsg() and adf_iov_putmsg() have been merged
together maintaining the adf_iov_putmsg() name.
This will allow to use this function only for GEN2 devices, since
collision are peculiar of this generation and therefore should be
confined to the actual implementation of the transport/medium access.
Note that now adf_iov_putmsg() will retry to send a message only in case
of collisions and will now fail if an ACK is not received from the
remote function.

Change the PFVF receipt flow on the VF side to read, ack and handle the
message instead of read, handle and ack.
This is done for (1) consistency with the PF side, see the function
adf_recv_and_handle_vf2pf_msg() in adf_pf2vf_msg.c, and (2) performance
reasons, to avoid keeping the CSR busy while parsing the message.
In addition, do not ACK PFVF legacy messages, as this driver is not
capable of handling PFVF legacy messages.
If a PFVF message with MSGORIGIN not set is received, do nothing.

Move the interrupt handling call from the PF specific protocol file,

the protocol handling.
The function adf_vf2pf_req_hndl() has been renamed as
adf_recv_and_handle_vf2pf_msg() to reflect its actual purpose and
maintain consistency with the VF side. This function now returns a
boolean indicating to the caller if interrupts need to be re-enabled or
not.

Move the reading and parsing of a PF2VF message from the bottom half
function in adf_vf_isr.c, adf_pf2vf_bh_handler(), to the PFVF protocol
file adf_vf2pf_msg.c, for better code organization.
The receive and handle logic has been moved to a new function called
adf_recv_and_handle_pf2vf_msg() which returns a boolean indicating if
interrupts need to be re-enabled or not.
A slight refactoring has been done to avoid calculating the PF2VF CSR
offset twice and repeating the clearing of the PF2VFINT bit.
The "PF restarting" logic, now defined in the function
adf_pf2vf_handle_pf_restaring(), has been kept in adf_vf_isr.c due to
the dependencies with the adf_vf_stop_wq workqueue.

If the remote function did not ACK the reception of a message, the
function __adf_iov_putmsg() could detect it as a collision.
This was due to the fact that the collision and the timeout checks after
the ACK loop were in the wrong order. The timeout must be checked at the
end of the loop, so fix by swapping the order of the two checks.

Pull overflow updates from Kees Cook:
"The end goal of the current buffer overflow detection work[0] is to
gain full compile-time and run-time coverage of all detectable buffer
overflows seen via array indexing or memcpy(), memmove(), and
memset(). The str*() family of functions already have full coverage.
While much of the work for these changes have been on-going for many
releases (i.e. 0-element and 1-element array replacements, as well as
avoiding false positives and fixing discovered overflows[1]), this
series contains the foundational elements of several related buffer
overflow detection improvements by providing new common helpers and
FORTIFY_SOURCE changes needed to gain the introspection required for
compiler visibility into array sizes. Also included are a handful of
already Acked instances using the helpers (or related clean-ups), with
many more waiting at the ready to be taken via subsystem-specific
trees[2].
The new helpers are:
- struct_group() for gaining struct member range introspection
- memset_after() and memset_startat() for clearing to the end of
structures
- DECLARE_FLEX_ARRAY() for using flex arrays in unions or alone in
structs
Also included is the beginning of the refactoring of FORTIFY_SOURCE to
support memcpy() introspection, fix missing and regressed coverage
under GCC, and to prepare to fix the currently broken Clang support.
Finishing this work is part of the larger series[0], but depends on
all the false positives and buffer overflow bug fixes to have landed
already and those that depend on this series to land.
As part of the FORTIFY_SOURCE refactoring, a set of both a
compile-time and run-time tests are added for FORTIFY_SOURCE and the
mem*()-family functions respectively. The compile time tests have
found a legitimate (though corner-case) bug[6] already.
Please note that the appearance of "panic" and "BUG" in the
FORTIFY_SOURCE refactoring are the result of relocating existing code,
and no new use of those code-paths are expected nor desired.
Finally, there are two tree-wide conversions for 0-element arrays and
flexible array unions to gain sane compiler introspection coverage
that result in no known object code differences.
After this series (and the changes that have now landed via netdev and
usb), we are very close to finally being able to build with
-Warray-bounds and -Wzero-length-bounds.
However, due corner cases in GCC[3] and Clang[4], I have not included
the last two patches that turn on these options, as I don't want to
introduce any known warnings to the build. Hopefully these can be
solved soon"

A struct pci_driver is shared across all device instances, so assigning
pci_driver.err_handler once per device isn't really sensible.
Set adf_driver.err_handler statically instead of in adf_enable_aer().
This removes a use of pci_dev->driver, which is a step toward removing
pci_dev->driver altogether.
Since adf_enable_aer() returns zero unconditionally, make it a void
function.

In the function adf_vf2pf_request_version(), the VF sends a request to
the PF and waits for a response before parsing and handling it.
Since this pattern will be used by other requests, define a new
function, adf_send_vf2pf_req(), that only deals with sending a VF2PF
request and waiting for a response.

The send function, adf_iov_putmsg(), is shared by both PF and VF.
This commit provides two direction specific APIs, adf_send_pf2vf_msg()
and adf_send_vf2pf_msg() which decouple the implementation, which can
change and evolve over time, from the user.
With this change, the adf_iov_putmsg() is now isolated inside the file
adf_pf2vf_msg.c and has been marked as static.
