It's possible for a user defined structure with .align directive to force by '32' or larger, and then allocator happens to have similar check upon SMP_CACHE_BYTES like case in this thread. Because both structure definition and allocator may have no idea about IA64 trick of saving space for UP. Max alignment of any C style only solves the natural alignment case, but not above forced one. We can just give its real assumption to SMP_CACHE_BYTES - cache line size. ;-) Not likely to be a problem. Memory allocators generally guarantee only 16-byte alignment (as per ia64 software conventions). --david -- Mosberger Consulting LLC, voice/fax: 510-744-9372, http://www.mosberger-consulting.com/ 35706 Runckel Lane, Fremont, CA 94536 - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.htmlReceived on Thu Nov 24 03:31:37 2005
