Currently, the only error that htab_remove_mapping() can report is -EINVAL, if removal of bolted HPTEs isn't implemeted for this platform. We make a few clean ups to the handling of this: * EINVAL isn't really the right code - there's nothing wrong with the function's arguments - use ENODEV instead * We were also printing a warning message, but that's a decision better left up to the callers, so remove it * One caller is vmemmap_remove_mapping(), which will just BUG_ON() on error, making the warning message redundant, so no change is needed there. * The other caller is remove_section_mapping(). This is called in the memory hot remove path at a point after vmemmap_remove_mapping() so if hpte_removebolted isn't implemented, we'd expect to have already BUG()ed anyway. Put a WARN_ON() here, in lieu of a printk() since this really shouldn't be happening.
