When I think a bit more of it, one probably should update the PSR after
the heir has been acquired, as the task could potentially be acquired
and released again with a new PSR by another core before the swap.

Hello,
I experienced a bug when using 4.11 SMP on a LEON4 system. One of the
tasks in my program suddenly lost the FPU enable bit in the PSR register
after a task switch. I tracked down the problem being due to the task
switching code not updating the PSR if the heir changes during the
switch
