Merge branches 'acpi-tools' and 'pm-tools'
* acpi-tools:
ACPI / tools: Introduce ec_access.c - tool to access the EC
* pm-tools:
cpupower: Remove mc and smt power aware scheduler info/settings
cpupower: cpupower info -b should return 0 on success, not the perf bias value
cpupower: If root, try to load msr driver on x86 if /dev/cpu/0/msr is not available
cpupower: Install recently added cpupower-idle-{set, info} manpages
cpupower: Introduce idle state disable-by-latency and enable-all
cpupower: Remove all manpages on make uninstall
cpupower: Remove dead link to homepage, and update the targets built.
cpupower: Rename cpufrequtils -> cpupower, and libcpufreq -> libcpupower.
PM / tools: cpupower: add option to display values without round offs
tools / power: turbostat: Drop temperature checks
