Pull x86 PTI and Spectre related fixes and updates from Ingo Molnar:
 "Here's the latest set of Spectre and PTI related fixes and updates:

  Spectre:
   - Add entry code register clearing to reduce the Spectre attack
     surface
   - Update the Spectre microcode blacklist
   - Inline the KVM Spectre helpers to get close to v4.14 performance
     again.
   - Fix indirect_branch_prediction_barrier()
   - Fix/improve Spectre related kernel messages
   - Fix array_index_nospec_mask() asm constraint
   - KVM: fix two MSR handling bugs

  PTI:
   - Fix a paranoid entry PTI CR3 handling bug
   - Fix comments

  objtool:
   - Fix paranoid_entry() frame pointer warning
   - Annotate WARN()-related UD2 as reachable
   - Various fixes
   - Add Add Peter Zijlstra as objtool co-maintainer

  Misc:
   - Various x86 entry code self-test fixes
   - Improve/simplify entry code stack frame generation and handling
     after recent heavy-handed PTI and Spectre changes. (There's two
     more WIP improvements expected here.)
   - Type fix for cache entries

  There's also some low risk non-fix changes I've included in this
  branch to reduce backporting conflicts:

   - rename a confusing x86_cpu field name
   - de-obfuscate the naming of single-TLB flushing primitives"

x86/cpu: Rename cpu_data.x86_mask to cpu_data.x86_stepping

2018-02-15T00:15:52+00:00

x86_mask is a confusing name which is hard to associate with the
processor's stepping.

Additionally, correct an indent issue in lib/cpu.c.

hwmon: (k10temp) Only apply temperature offset if result is positive

2018-02-12T22:23:29+00:00

A user reports a really bad temperature on Ryzen 1950X.

k10temp-pci-00cb
Adapter: PCI adapter
temp1: +4294948.3°C (high = +70.0°C)

This will happen if the temperature reported by the chip is lower than
the offset temperature. This has been seen in the field if "Sense MI Skew"
and/or "Sense MI Offset" BIOS parameters were set to unexpected values.
Let's report a temperature of 0 degrees C in that case.

hwmon: (dell-smm) Disable fan support for Dell Vostro 3360

2018-01-27T17:34:22+00:00

Calling fan related SMM functions implemented by Dell BIOS firmware on Dell
Vostro 3360 freeze kernel for about 500ms.

Unfortunately, it is unlikely for Dell to fix this since the machine
is pretty old, so this commit just disables fan support to make the
system usable again.

Via "force" module param fan support can be enabled.

hwmon: (dell-smm) Disable fan support for Dell Inspiron 7720

2018-01-27T17:34:03+00:00

Calling fan related SMM functions implemented by Dell BIOS firmware on Dell
Inspiron 7720 freeze kernel for about 500ms. Until Dell fixes it we need to
disable fan support for Dell Inspiron 7720 as it makes system unusable.

Via "force" module param fan support can be enabled.

hwmon: (dell-smm) Enable broken functionality via "force" module param

2018-01-27T17:33:38+00:00

Some Dell machines are broken and some functionality is disabled. Show
warning into dmesg about this fact and allow user via "force" module param
to override brokenness and enable broken functionality.

hwmon: (lm75) Fix trailing semicolon

The trailing semicolon is an empty statement that does no operation.
Removing it since it doesn't do anything.

hwmon: (ina2xx) Fix access to uninitialized mutex

2018-01-15T16:01:45+00:00

Initialize data->config_lock mutex before it is used by the driver code.

This fixes following warning on Odroid XU3 boards:
