Some users have been reporting issues with thunderbolt being turned off
before fully initialized. This is suspected to be caused by userspace
turning off the Thunderbolt controller using intel-wmi-thunderbolt
prematurely.
Userspace has already made some mitigations for this situation:
https://github.com/hughsie/fwupd/commit/ef6f1d76983c9b66https://github.com/hughsie/fwupd/commit/c07ce5b4889a5384
To allow easier debugging of this situation add output that can be turned
on with dynamic debugging to better root cause this problem.

The dell_rbu driver takes firmware update payloads and puts them in memory so
the system BIOS can find them after a reboot. This sometimes fails (though
rarely), because the memory containing the payload is in the CPU cache but
never gets written back to main memory before the system is rebooted (CPU
cache contents are lost on reboot).
With this patch, the payload memory will be changed to uncachable to ensure
that the payload is actually in main memory before the system is rebooted.

There is a table of Vendor/Model/Version {control data} in this driver,
but outside of the initial probe, the V/M/V is never used again, and
neither are any of the entries for platforms other than the one which
matches the running target.
By simply storing the {control data} for the matched platform, we can
mark the large table __initconst, which reduces the loaded driver size
by 20 percent.

As can be seen in the context, the BIOS registers haven't changed in
the previous versions, so the assumption is they won't have changed
in this last update for this somewhat older platform either.

Just like we avoid specifying actual block devices like sda for fdisk
and dd examples, we should not specify specific thermal zones here.
On the platform I was testing on, zone0 was acpitz, and zone1 was for
this acerhdf driver. Make the printk such that it won't work with a
blind cut-and-paste, and force the user to determine which zone is
correct for this driver.

This driver has two module parameters that allow an override of the
checks for matching model and BIOS version. However, both parameters
expect you to choose an entry from the existing list of supported
systems, encoded within the driver itself.
Without the source, such as in a binary distribution, the end user
does not have access to this information, thus rendering the two
module parameters essentially useless.
Add a module parameter that allows the end user to dump the list
of make/model/versions so that they can then pick one that most
closely matches their own system.

Normally, a module parameter for a BIOS check override implies "pretend
you support this version" (and the user will enter their local version).
However, this driver uses the model/BIOS module parameters in a way that
is "pretend my system is the supported model XYZ with BIOS version ABC."
which is less common.
Since the help strings don't make such a distinction, one gets this
somewhat frustrating scenario, where the user sees the error, enters
*their* BIOS version and then gets the same error:
root@gw:~# modprobe acerhdf
acerhdf: Acer Aspire One Fan driver, v.0.7.0
acerhdf: unknown (unsupported) BIOS version Gateway /LT31 /v1.3307 , please report, aborting!

acerhdf: forcing BIOS version: v1.3307
acerhdf: unknown (unsupported) BIOS version Gateway /LT31 /v1.3307 , please report, aborting!
modprobe: ERROR: could not insert 'acerhdf': Invalid argument
Clarify the module param help text to make it clear that the driver
expects a choice from existing supported models/versions.

The intel_int0002_vgpio driver was added to avoid an IRQ 9 storm on Cherry
Trail platforms.
When originally merged the CPU ID for Bay Trail SoCs was commented out
of the list of valid CPU IDs because we did not have any reports of the
IRQ storm on Bay Trail platforms.
We now have a report of the IRQ 9 storm on the Bay Trail based Thinkpad
Tablet 10 which is fixed by enabling this driver, so lets enable it on
Bay Trail too.
I've tested various other Bay Trail device with this driver enabled
without adverse side-effects.
