[RFC PATCH] powerpc: Implement hotplug smt control

2022-02-16 Thread Joel Stanley
x86 added a control for turning SMT on and off in commit 05736e4ac13c ("cpu/hotplug: Provide knobs to control SMT"). Implement this for powerpc as an alternative to the currently method of iterating through /sys/devices/system/cpu/cpuN/online for every CPU. # ppc64_cpu --info Core 0:0*
