Hi Fengguang,
I don't really understand if this is a real bug that I need to fix?
It looks like a linker problem, resulting in a "Segmentation fault" for your script...
The mentioned commit: d0ecd894e3d5f768a84 removes a call point to
__slab_free() and instead call slab_free(). It does not make sense to
my, why this results in a linker error on this ARCH=microblaze.
