| This patch alows using 64 bit atomic instructions on a |
| 32 bit platform. This is safe, providing x86 is Pentium or |
| later (would not work on i386, i486). Using 64 bit atomic |
| instructions bypasses code containing a bug as documented in |
| https://bugzilla.yoctoproject.org/show_bug.cgi?id=8140 |
