Merge note, there will be a bunch of conflicts with the cpufreq
tree which you just pulled:
drivers/cpufreq/Kconfig.x86
drivers/cpufreq/Makefile
Due to these commits that crossed:
6fb302d2109c cpufreq: elanfreq: Drop support for AMD Elan SC4*
7dd383dc6693 cpufreq: clean up dead dependencies on X86 in Kconfig
The resolution should be the superset of all the removals.
Thanks,
Ingo
