-Earlier, with DMEM queue, if command needs in/out payload
then space needs to be allocated in DMEM/FB-surface &
copy payload in allocated space before sending command
by providing payload info in sending command .
-With FBQ, command in/out payload is also part of FB command
queue element & not required to allocate separate space in
DMEM/FB-surface, so added changes to handle FBQ payload request
while sending command & also in response handler to extract

The Tegra SOC nvlink driver and dGPU nvlink driver depend on
struct definitions, macros and functions exposed by nvlink-core
driver. The nvlink-core driver is not part of the nvgpu driver,
hence we should not be directly accessing any core driver
APIs/macros/structs from the /common/nvlink code. Common code can
only use nvgpu internal APIs. We wrap all calls from common/nvlink.c
to other drivers in nvgpu wrappers, and define the implementation of
wrappers in os/linux and os/nvgpu_rmos, and stub them in os/posix.
Also, we remove the implicit inclusion of OS specific nvlink header
file via common nvgpu/nvlink.h. So the OS specific code needs to
explicitly add OS specific header file.

While not necessary for MISRA compliance purposes, this change
modifies the linux platform clk code use of container_of() to follow
similar changes applied to address the following rule violations:
* Rule 11.3 : A cast shall not be performed between a pointer to
object type and a pointer to a different object type.
* Rule 11.8 : A cast shall not remove any const or volatile
qualification from the type pointed to be a pointer.
* Rule 20.7 : Expressions resulting from the expansion of macro
parameters shall be enclosed in parentheses.
This patch replaces the to_clk_gk20a() macro with a new (static)
clk_gk20a_from_hw() function that eliminates the Rule 11.8 and
Rule 20.7 violations and exchanges the Rule 11.3 violation with
an advisory Rule 11.4 violation.
It should be noted that the replacement function still contains
potentially dangerous (and non-MISRA compliant code) and that it is
expected that deviation requests will be filed for the new advisory
rule violations where appropriate.

Add an address book that lets devs use short hand for specifying
--to and --cc targets. For example, if a dev wants to CC the MISRA
list this can be used:
$ ./scripts/rfr -e --cc misra ...
The address book also lets devs add their own names/email addresses
since this makes it convenient to CC individual people. For example:
$ ./scripts/rfr -e --cc alex ...
Several new arguments were added to support the address book. There
are arguments to list/search the address book, ignore the address
book, and to prevent nvgpu-core from being added to the to address
by default. For more details see the help page.
To use an address book there's several options: place one at
~/.rfr-addrbook
Export an RFR_ADDRBOOK environment variable pointing to the address
book, or specify one with the `-a' option. The address book contents
is simple. All empty lines and lines beginning with '#' are ignored.
The remaining lines are split by '|' and the first half of the line
is considered a nickname and the latter half the address. An example:
alex | alex waterman <alexw@nvidia.com>
This will let you specify `--to alex' instead of the full email
address. This is especially useful for mailing lists.
Lastly there is more documentation located at:
