Pull misc x86 updates from Borislav Petkov:
 "The main part of this branch is the ongoing fight against windmills in
  an attempt to have userspace tools not poke at naked MSRs.

  This round deals with MSR_IA32_ENERGY_PERF_BIAS and removes direct
  poking into it by our in-tree tools in favor of the proper
  "energy_perf_bias" sysfs interface which we already have.

  In addition, the msr.ko write filtering's error message points to a
  new summary page which contains the info we collected from helpful
  reporters about which userspace tools write MSRs:

      https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/about

  along with the current status of their conversion.

  The rest is the usual small fixes and improvements"
