/usr/src/25/arch/x86/include/asm/compat.h:301: error: dereferencing pointer to incomplete type
Problem is, compat.h's arch_compat_alloc_user_space() needs sched.h for
task_struct but as you can see from the above include tree, sched.h
includes seccomp.h and everything falls over. The preprocessed code
contains the definition of arch_compat_alloc_user_space() *before* the
definition of task_struct.
This is a basic x86_64 "make clean; make allmodconfig; make".
