These pxd_ERROR() macros have been provided by all platforms which basically did the same thing. Make pxd_clear_bad() use recently added ptval_to_str() instead for printing page table entries thus completely dropping dependency on platform provided pxd_ERROR() macros which can then be dropped off later on.
