From c396afdfa4a09391533f0e1eb3a765dc43884e85 Mon Sep 17 00:00:00 2001 From: Kirk Meyer Date: Fri, 14 Jun 2013 10:11:02 +1000 Subject: MicroBlaze: negated errors in lowlevellock.h The macros in lowlevellock.h are returning positive errors, but the users of the macros expect negative. This causes e.g. sem_wait to sometimes return an error with errno set to -EWOULDBLOCK.
