Since f6bec26c0a7 (mm/execmem, arch: convert simple overrides of module_alloc to execmem)
sparc was accidentaly changed to map module memory w/ VM_FLUSH_RESET_PERMS, causing
page tables or memory corruption on each module load, making it even nearly impossible
to even successfully boot sun4u systems.
