>Description:

	powerpc should support access to the fpu/altivec in the
	kernel with something similar to fpu_kern_enter/leave on
	other architectures.  (Whether there should be a separate
	altivec_kern_enter/leave is left as an exercise for the
	fixer.)

>How-To-Repeat:

	port openzfs

>Fix:

	Yes, please!
