[PATCH] x86_64: Use common sys_time64
Keeping this function does not makes sense because it's a copied (and buggy) copy of sys_time. The only difference is that now.tv_sec (which is a time_t, i.e. a 64-bit long) is copied (and truncated) into a int (32-bit). The prototype is the same (they both take a long __user *), so let's drop this and redirect it to sys_time (and make sure it exists by defining __ARCH_WANT_SYS_TIME). Only disadvantage is that the sys_stime definition is also compiled (may be fixed if needed by adding a separate __ARCH_WANT_SYS_STIME macro, and defining it for all arch's defining __ARCH_WANT_SYS_TIME except x86_64).
