      Un-inline the core-dump helper functions · 3aa0ce82
      Linus Torvalds authored
      Tony Luck reports that the addition of the access_ok() check in commit
      0eead9ab ("Don't dump task struct in a.out core-dumps") broke the
      ia64 compile due to missing the necessary header file includes.
      
      Rather than add yet another include (<asm/unistd.h>) to make everything
      happy, just uninline the silly core dump helper functions and move the
      bodies to fs/exec.c where they make a lot more sense.
      
      dump_seek() in particular was too big to be an inline function anyway,
      and none of them are in any way performance-critical.  And we really
      don't need to mess up our include file headers more than they already
      are.

      Don't dump task struct in a.out core-dumps · 0eead9ab
      Linus Torvalds authored
      akiphie points out that a.out core-dumps have that odd task struct
      dumping that was never used and was never really a good idea (it goes
      back into the mists of history, probably the original core-dumping
      code).  Just remove it.
      
      Also do the access_ok() check on dump_write().  It probably doesn't
      matter (since normal filesystems all seem to do it anyway), but he
      points out that it's normally done by the VFS layer, so ...
      
      [ I suspect that we should possibly do "vfs_write()" instead of
        calling ->write directly.  That also does the whole fsnotify and write
        statistics thing, which may or may not be a good idea. ]
      
      And just to be anal, do this all for the x86-64 32-bit a.out emulation
      code too, even though it's not enabled (and won't currently even
      compile)

      hrtimer: Preserve timer state in remove_hrtimer() · f13d4f97
      Salman Qazi authored
      The race is described as follows:
      
      CPU X                                 CPU Y
      remove_hrtimer
      // state & QUEUED == 0
      timer->state = CALLBACK
      unlock timer base
      timer->f(n) //very long
                                        hrtimer_start
                                          lock timer base
                                          remove_hrtimer // no effect
                                          hrtimer_enqueue
                                          timer->state = CALLBACK |
                                                         QUEUED
                                          unlock timer base
                                        hrtimer_start
                                          lock timer base
                                          remove_hrtimer
                                              mode = INACTIVE
                                              // CALLBACK bit lost!
                                          switch_hrtimer_base
                                                  CALLBACK bit not set:
                                                          timer->base
                                                          changes to a
                                                          different CPU.
      lock this CPU's timer base
      
      The bug was introduced with commit ca109491 (hrtimer: removing all ur
      callback modes) in 2.6.29
