    PR21255: Fix missing get_task_mm() declaration.
    
    * buildrun.cxx (compile_pass): Add <linux/sched/mm.h> autoconf test. This
      was caused by the following kernel commit:
    
        commit 6e84f31522f931027bf695752087ece278c10d3f
        Author: Ingo Molnar <mingo@kernel.org>

            sched/headers: Prepare for new header dependencies before moving
            code to <linux/sched/mm.h>
    * runtime/linux/access_process_vm.h: Include <linux/sched.h> and, if it
      exists, <linux/sched/mm.h>.
    * runtime/linux/autoconf-sched-mm.c: New file.
