If symbol_conf.priv_size is not a multiple of "sizeof(u64)" we'll bus error on sparc64 in symbol__new because the "struct symbol *" pointer is computed by adding symbol_conf.priv_size to the memory allocated. We cannot isolate the fix to symbol__new and symbol__delete since the private area is computed by subtracting the priv_size value from a "struct symbol" pointer, so then the private area can still be potentially unaligned. So, simply align the symbol_conf.priv_size value in symbol__init() Cc: Ingo Molnar <mingo@elte.hu> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> LKML-Reference: <20110328.175849.112593455.davem@davemloft.net> Signed-off-by: David S.
