Subject: Fix stat64 structure on 32-bit X86_SE
X-Git-Tag: stable_2012_02_02~1697

Fix stat64 structure on 32-bit X86_SE

The st_size entry was in the wrong place
 (see linux-2.6.29/arch/x86/include/asm/stat.h )

Also, the packed attribute is needed when compiling on a
64-bit machine, otherwise gcc adds extra padding that
break the layout of the structure.
