Do not limitate to the 3 (100KHz, 400KHz, 1MHz) bus frequency but
instead allows any frequency (if it matches timing requirements).
Depending on the requested frequency, use the spec data from either
Standard, Fast or Fast Plus mode.

Hardcoding of min/max bus frequencies is removed and is instead computed.

The driver do not use anymore speed identifier but instead handle
directly the frequency and figure out the spec data (necessary
for the computation of the timing register) based on the frequency.

The AMD X370 and other AM4 chipsets (A/B/X 3/4/5 parts) and Threadripper
equivalents have a secondary SMBus controller at I/O port address
0x0B20.  This bus is used by several manufacturers to control
motherboard RGB lighting via embedded controllers.  I have been using
this bus in my OpenRGB project to control the Aura RGB on many
motherboards and ASRock also uses this bus for their Polychrome RGB
controller.

I am not aware of any CZ-compatible platforms which do not have the
second SMBus channel.  All of AMD's AM4- and Threadripper- series
chipsets that OpenRGB users have tested appear to have this secondary
bus.  I also noticed this secondary bus is present on older AMD
platforms including my FM1 home server.

This sorts the actual field names too, potentially causing even more

it's a one-time pain minimized by doing this just before the -rc1
release.

They are all supposed to be sorted, but people who add new entries don't
always know the alphabet.  Plus sometimes the entry names get edited,
and people don't then re-order the entry.

Let's see how painful this will be for merging purposes (the MAINTAINERS
file is often edited in various different trees), but Joe claims there's
relatively few patches in -next that touch this, and doing it just
before -rc1 is likely the best time.  Fingers crossed.

This was scripted with

  /scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS

but then I also ended up manually upper-casing a few entry names that
stood out when looking at the end result.

 "A set of three patches to fix the fallout of the newly added split
  lock detection feature.

  It addressed the case where a KVM guest triggers a split lock #AC and
  KVM reinjects it into the guest which is not prepared to handle it.

  Add proper sanity checks which prevent the unconditional injection
  into the guest and handles the #AC on the host side in the same way as
  user space detections are handled. Depending on the detection mode it
  either warns and disables detection for the task or kills the task if
  the mode is set to fatal"

Two types of #AC can be generated in Intel CPUs:

Reflect #AC back into the guest if the guest has legacy alignment checks
enabled or if split lock detection is disabled.

If the #AC is not a legacy one and split lock detection is enabled, then
invoke handle_guest_split_lock() which will either warn and disable split
lock detection for this task or force SIGBUS on it.

Emulate split-lock accesses as writes if split lock detection is on
to avoid #AC during emulation, which will result in a panic(). This
should never occur for a well-behaved guest, but a malicious guest can
manipulate the TLB to trigger emulation of a locked instruction[1].

Without at least minimal handling for split lock detection induced #AC,
VMX will just run into the same problem as the VMWare hypervisor, which
was reported by Kenneth.

It will inject the #AC blindly into the guest whether the guest is
prepared or not.

Provide a function for guest mode which acts depending on the host
SLD mode. If mode == sld_warn, treat it like user space, i.e. emit a
warning, disable SLD and mark the task accordingly. Otherwise force
SIGBUS.
