Setting the FSCR bit directly in the SPR only sets it during the initial
boot and early init of the kernel but not for the init process or any
subsequent kthreads. This is because the thread_struct for those is
copied from the current thread_struct setup at boot which doesn't
reflect any changes made to the FSCR during cpu feature detection. This
patch ensures the current thread state is updated to match once feature
detection is complete.

I see that the series has been merged but this patch was left over.

Has it been forgotten or is it rejected ?
I fixed the underlying issue, see:

  912c0a7f2b5d ("powerpc/64s: Save FSCR to init_task.thread.fscr after feature init")

So I guess it was superseeded (by a preceeding patch).

cheers
