------------------------------------------------------
Subject: futex_compat: update to match native version
From: Arnd Bergmann <[EMAIL PROTECTED]>
A few changes have gone into the futex code but not into the futex_compat
code, the most significant one being a fix for FUTEX_WAKE_OP in commit
f54f098612d7f86463b5fb4763d03533d634de73.
This brings both versions in sync again.
