    timers: fix itimer/many thread hang, v2 · bb34d92f
    Frank Mayhar authored
    This is the second resubmission of the posix timer rework patch, posted
    a few days ago.
    This includes the changes from the previous resubmittion, which addressed
    Oleg Nesterov's comments, removing the RCU stuff from the patch and
    un-inlining the thread_group_cputime() function for SMP.
    In addition, per Ingo Molnar it simplifies the UP code, consolidating much
    of it with the SMP version and depending on lower-level SMP/UP handling to
    take care of the differences.
    It also cleans up some UP compile errors, moves the scheduler stats-related
    macros into kernel/sched_stats.h, cleans up a merge error in
    kernel/fork.c and has a few other minor fixes and cleanups as suggested
    by Oleg and Ingo. Thanks for the review, guys.
