Hi Andrew, After merging the akpm tree, today's linux-next build (any without CONFIG_MMU e.g. bfin BF537-STAMP_defconfig) failed like this: fs/proc/task_nommu.c:173: undefined reference to `vm_is_stack' Caused by commit "procfs: mark thread stack correctly in proc/<pid>/maps" from the akpm tree which only defines that function when CONFIG_MMU is set. -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx
