| |
Processor entries under /sys/firmware/acpi/namespace/ACPI/_SB/CPU* were not being removed due to acpi_bus_trim not asking for it just for processors. Without which a new hot-add after a remove doesnt call appropriate init functions resulting in subsequent hot-add for same cpu failing.
Not clear why we restricted that to non-processor devices.
