From ca073b4af90b7d2ec6fd6563bee06a68907999ad Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Thu, 27 Dec 2012 10:07:24 +0100 Subject: microblaze: Microblaze wants sys_fork for noMMU too The patch "generic sys_fork / sys_vfork / sys_clone" (sha1: d2125043aebf7f53cd1c72115c17b01d0bc06ce1) introduced generic sys_fork with implementation for noMMU which returns EINVAL for noMMU. and the patch "microblaze: switch to generic fork/vfork/clone" (sha1: f3268edbe6fe0ce56e62c6d6b14640aeb04864b7) enable sys_fork only for MMU which is causing compilation failure on noMMU system.
