In arch/ia64/ia32/sys_ia32.c, the function getname32 allocates storage via __get_free_page and then returns it via putname (aka kmem_cache_free). This mismatch of storage allocation schemes can cause all kinds of subtle problems as we found in PPC64. Is this a legitimate bug, or are we missing something here?
