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 processor: Remove unneeded cpuidle_unregister_driver call intel idle: Make idle driver more robust intel_idle: Fix a cast to pointer from integer of different size warning in intel_idle ACPI: kernel-parameters.txt : Add intel_idle.max_cstate intel_idle: remove redundant local_irq_disable() call ACPI processor: Fix error path, also remove sysdev link ACPI: processor: fix acpi_get_cpuid for UP processor intel_idle: fix API misuse ACPI APEI: Convert atomicio routines ACPI: Export interfaces for ioremapping/iounmapping ACPI registers ACPI: Fix possible alignment issues with GAS 'address' references ACPI, ia64: Use SRAT table rev to use 8bit or 16/32bit PXM fields (ia64) 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 ACPI, APEI, EINJ, Refine the fix of resource conflict ...
