Sure the BSPs compile but do all BSPs compile ?

What is the use case for this with RTEMS ?

Is there any user documentation about the supported architectures and 
its use in RTEMS ?

My concern is having a feature like this but not every architecture or 
BSP supporting it therefore creating non-portable RTEMS applications. 
How do we police this not being used in RTEMS and only tested on 
supported BSPs ? For example using TLS to fix the shell's environment 
task variables for use with SMP.
