The Linux kernel now checks for this before marking CPUs as
hotpluggable:

x86/ACPI: Don't add CPUs that are not online capable
A number of systems are showing "hotplug capable" CPUs when they
are not really hotpluggable. This is because the MADT has extra
CPU entries to support different CPUs that may be inserted into
the socket with different numbers of cores.
Starting with ACPI 6.3 the spec has an Online Capable bit in the
MADT used to determine whether or not a CPU is hotplug capable
when the enabled bit is not set.
