Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

Pull rdma updates from Jason Gunthorpe:
"This has been a slightly more active cycle than normal with ongoing
core changes and quite a lot of collected driver updates.
- Various driver fixes for bnxt_re, cxgb4, hns, mlx5, pvrdma, rxe
- A new data transfer mode for HFI1 giving higher performance
- Significant functional and bug fix update to the mlx5
On-Demand-Paging MR feature
- A chip hang reset recovery system for hns
- Change mm->pinned_vm to an atomic64
- Update bnxt_re to support a new 57500 chip
- A sane netlink 'rdma link add' method for creating rxe devices and
fixing the various unregistration race conditions in rxe's
unregister flow
- Allow lookup up objects by an ID over netlink
- Various reworking of the core to driver interface:
- drivers should not assume umem SGLs are in PAGE_SIZE chunks
- ucontext is accessed via udata not other means
- start to make the core code responsible for object memory
allocation
- drivers should convert struct device to struct ib_device via a
helper
- drivers have more tools to avoid use after unregister problems"

Being able to build devlink as a module causes growing pains.
First all drivers had to add a meta dependency to make sure
they are not built in when devlink is built as a module. Now
we are struggling to invoke ethtool compat code reliably.
Make devlink code built-in, users can still not build it at
all but the dynamically loadable module option is removed.

The next patch will add dependency from ib_umem_get in to ib_uverbs so
move the required ib_umem_xxx functionality to it's correct module -
ib_uverbs - and avoid circular dependecy from the form of ib_core ->
ib_uverbs -> ib_core in depmod.
Since this now requires all drivers to be build modular if uverbs is
modular, hoist the test a couple drivers had into the main kconfig and
apply it to all drivers uniformly.

The mlx4 driver produces a link error when it is configured
as built-in while CONFIG_INFINIBAND_USER_ACCESS is set to =m:
drivers/infiniband/hw/mlx4/main.o: In function `mlx4_ib_mmap':
main.c:(.text+0x1af4): undefined reference to `rdma_user_mmap_io'
The same function is called from mlx5, which already has a
dependency to ensure we can call it, and from hns, which
appears to suffer from the same problem.
This adds the same dependency that mlx5 uses to the other two.

The new NET_DEVLINK infrastructure can be a loadable module, but the drivers
using it might be built-in, which causes link errors like:
drivers/net/built-in.o: In function `mlx4_load_one':
:(.text+0x2fbfda): undefined reference to `devlink_port_register'
:(.text+0x2fc084): undefined reference to `devlink_port_unregister'
drivers/net/built-in.o: In function `mlxsw_sx_port_remove':
:(.text+0x33a03a): undefined reference to `devlink_port_type_clear'
:(.text+0x33a04e): undefined reference to `devlink_port_unregister'
There are multiple ways to avoid this:
a) add 'depends on NET_DEVLINK || !NET_DEVLINK' dependencies
for each user
b) use 'select NET_DEVLINK' from each driver that uses it
and hide the symbol in Kconfig.
c) make NET_DEVLINK a 'bool' option so we don't have to
list it as a dependency, and rely on the APIs to be
stubbed out when it is disabled
d) use IS_REACHABLE() rather than IS_ENABLED() to check for
NET_DEVLINK in include/net/devlink.h
This implements a variation of approach a) by adding an
intermediate symbol that drivers can depend on, and changes
the three drivers using it.

Since mlx4_ib supports IP based addressing, a dependency on INET needs
to be added, since mlx4_ib registers itself for net device events.

Add an InfiniBand driver for Mellanox ConnectX adapters. Because
these adapters can also be used as ethernet NICs and Fibre Channel
HBAs, the driver is split into two modules:
mlx4_core: Handles low-level things like device initialization and
processing firmware commands. Also controls resource allocation
so that the InfiniBand, ethernet and FC functions can share a
device without stepping on each other.
mlx4_ib: Handles InfiniBand-specific things; plugs into the
InfiniBand midlayer.
