Avoid declaring ALIGN() and __aligned() in include/uapi/linux/mic_common.h since they pollute user space namespace. Also, mic_aligned_size() can be simply replaced simply by sizeof() since all structures where mic_aligned_size() is used are declared using __attribute__ ((aligned(8))); -- >From mail from H Peter Anvin about this: On Fri, Nov 08, 2013 H Peter Anvin <h.peter.anvin@intel.com> wrote: Subject: Namespace pollution in mic_common.h This puts two macros, ALIGN() and __aligned(), into arbitrary user space namespace. This really isn't safe or acceptable, especially since those symbols are highly generic. ... When these structures are forced-aligned, they will in fact have padding automatically added by the compiler to an 8-byte boundary anyway, so mic_aligned_size() does nothing. ...
