Changes in s390x uaccess.h in 2.4.17+

Hello:

The 2.4.17 patch comes with a change to uaccess.h, which contains the following:

- * These functions have a non-standard call interface
+ * These functions have standard call interface

Does it look familiar to anyone? The change is in Marcelo's tree now, but I am curious what it actually does.

The 2.4.17 patch readme says "This patch contains the current recommended kernel 2.4.7 code base (up to 2002-01-21), adapted to kernel 2.4.17.", but I cannot find this change in any published 2.4.7 patches. I am pretty sure there must be a good reason for the change, and it's interesting to know what it is.
