From f6a12a7d0b1a70e969ae4f6d7c5201cdaf6edde0 Mon Sep 17 00:00:00 2001 From: "Meyer, Kirk" Date: Thu, 23 May 2013 17:06:57 +0000 Subject: [PATCH] microblaze: Reversed logic in futex cmpxchg futex_atomic_cmpxchg_inatomic exchanged if the values were unequal rather than equal. This caused incorrect behavior of robust futexes.
