ConnectX-4/5 devices in mlx5core.
The dump is obtained by reading a predefined register map from the
non-destructive crspace, accessible by the vendor-specific PCIe
capability (VSC). The dump is stored in preallocated kernel memory and
managed by the mlx5tool(8), which communicates with the driver using a
character device node.
The utility allows to store the dump in format
<address> <value>
into a file, to reset the dump content, and to manually initiate the
dump.
A call to mlx5_fwdump() should be added at the places where a dump
must be fetched automatically. The most likely place is right before a
firmware reset request.

Add support for PFC and implement reading the per priority statistics
using the sysctl(8) interface. PFC is used together with VLAN priority
and can be enabled and disabled on a per priority basis.
Global pause frames and PFC are incompatible features and surrounding
logic has been added to warn the user about misconfiguration.
Update relevant mlx5core APIs for PFC configuration.

cli_execute was changed to return the status, cascade that to
cli_execute_unparsed.
This fixes a lot of false "Failed to execute" errors following r330620; no
failures actually occurred, but [module]_error would've then promptly
executed (and also "failed")
there is a valid reservation. This can trip erroneously when memory
falls within a domain but doesn't have the reservation initialized because
it does not meet size or alignment requirements.

These tend to have less coverage in other places and they don't have
defaults as of yet, so mention them here:
- fdt_overlays
- kernels_autodetect (lualoader only)
This applies to:
- exec
- [module]_before
- [module]_error
- [module]_after
Before this commit, these used loader.perform to execute them as a pure,
unsalted loader command. This means that they were not able to take
advantage of any Lua-salted loader commands, like boot and autoboot, or pure
Lua loader commands (functions attached to the 'cli' module).
They now have access to the full arsenal, just shy of being able to execute
arbitrary Lua.
loader.interpret should not be used for executing loader commands from an
untrusted source (e.g. environment vars) as it will allow execution of
arbitrary Lua. Replace it with a call to the recently introduced
cli_execute_unparsed, which parses it out as a loader command and then
dispatches it as a loader command. This effectively filters out arbitrary
Lua.
This will be used for scenarios where the command to execute is coming in
via the environment (from, for example, loader.conf(5)) and is thus not
necessarily trusted.
cli_execute_unparsed will immediately be used for handling
module_{before,after,error} as well as menu_timeout_command. We still want
to offer these variables the ability to execute Lua-intercepted loader
commands, but we don't want them to be able to execute arbitrary Lua.

LLD is a cross toolchain component. It shouldn't be built when

accomplishes a few things:
- Makes NULL an invalid address in the kernel, which is useful for catching
bugs.
- Lays groundwork for radix-tree translation on POWER9, which requires the
direct map be at high memory.
- Similarly lays groundwork for a direct map on 64-bit Book-E.
The new base address is chosen as the base of the fourth radix quadrant
(the minimum kernel address in this translation mode) and because all
supported CPUs ignore at least the first two bits of addresses in real
mode, allowing direct-map addresses to be used in real-mode handlers.
This is required by Linux and is part of the architecture standard
starting in POWER ISA 3, so can be relied upon.

The current implementation does not handle timeout in case of command
with callback request, and this can lead to deadlock if the command
doesn't get firmware response. Add delayed callback timeout work
before posting the command to firmware. In case of real firmware
command completion we will cancel the delayed work. In case of
firmware command timeout the callback timeout handler will be called
and it will simulate firmware completion with timeout error.
