[PATCH] Removal of *user_ret macros

[PATCH] Removal of *user_ret macros

[SL Baur]

This is a janitor patch to remove some of the remaining *user_ret
macros that were missed.  I am told the ones in parisc have already
been fixed and are waiting a merge.  This patch was done against 2.5
bk current, but it will apply to 2.4 as well.


You can import this changeset into BK by piping this whole message to:

  Janitor clean up.  Macros containing return statements are evil.
