Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux

This includes initial support for the recently published ACPI 5.0 spec.
In particular, support for the "hardware-reduced" bit that eliminates
the dependency on legacy hardware.

APEI has patches resulting from testing on real hardware.

Plus other random fixes.

* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux: (52 commits)
  acpi/apei/einj: Add extensions to EINJ from rev 5.0 of acpi spec
  intel_idle: Split up and provide per CPU initialization func
  ACPI processor: Remove unneeded variable passed by acpi_processor_hotadd_init V2

  ACPI, x86: Use SRAT table rev to use 8bit or 32bit PXM fields (x86/x86-64)
  ACPI: Store SRAT table revision
  ACPI, APEI, Resolve false conflict between ACPI NVS and APEI
  ACPI, Record ACPI NVS regions
