    This reverts commit 9745cdb3 (select: use freezable blocking call)
    that triggers problems during resume from suspend to RAM on Paul Bolle's
    32-bit x86 machines.  Paul says:
    
      Ever since I tried running (release candidates of) v3.11 on the two
      working i686s I still have lying around I ran into issues on resuming
      from suspend. Reverting 9745cdb3 (select: use freezable blocking
      call) resolves those issues.
    
      Resuming from suspend on i686 on (release candidates of) v3.11 and
      later triggers issues like:
    
      traps: systemd[1] general protection ip:b738e490 sp:bf882fc0 error:0 in libc-2.16.so[b731c000+1b0000]
    
      and
    
      traps: rtkit-daemon[552] general protection ip:804d6e5 sp:b6cb32f0 error:0 in rtkit-daemon[8048000+d000]
    
      Once I hit the systemd error I can only get out of the mess that the
      system is at that point by power cycling it.
    
    Since we are reverting another freezer-related change causing similar
    problems to happen, this one should be reverted as well.
