Description
At this point in time, the SMP code is NOT tracking the FPU context on a per core basis. There needs to be some thought put into ensuring it can be made to work correctly and safely. Until that time, when SMP is enabled, this needs to be disabled.

Patch committed to head. When someone wants this supported, it will require work to implement (if it can be implemented) and this can be revisited.
