      ARM: SAMSUNG: use spin_lock_irqsave() in clk_set_parent · dbc5e1e8
      Mandeep Singh Baines authored
      From 0cdf3aff, "ARM: SAMSUNG: use spin_lock_irqsave() in
      clk_{enable,disable}":
      
        The clk_enable()and clk_disable() can be used process and ISR either.
        And actually it is used for real product and other platforms use it
        now. So spin_lock_irqsave() should be used instead.
      
      We need to make a similar change in clk_set_parent(). Otherwise,
      you can potentially get spinlock recursion:

      Revert "sched: Improve scalability via 'CPU buddies', which withstand random perturbations" · 37407ea7
      Linus Torvalds authored
      This reverts commit 970e1789.
      
      Nikolay Ulyanitsky reported thatthe 3.6-rc5 kernel has a 15-20%
      performance drop on PostgreSQL 9.2 on his machine (running "pgbench").
      
      Borislav Petkov was able to reproduce this, and bisected it to this
      commit 970e1789 ("sched: Improve scalability via 'CPU buddies' ...")
      apparently because the new single-idle-buddy model simply doesn't find
      idle CPU's to reschedule on aggressively enough.
      
      Mike Galbraith suspects that it is likely due to the user-mode spinlocks
      in PostgreSQL not reacting well to preemption, but we don't really know
      the details - I'll just revert the commit for now.
      
      There are hopefully other approaches to improve scheduler scalability
      without it causing these kinds of downsides.

      Pull driver core fix from Greg Kroah-Hartman:
       "Here is one fix for 3.6-rc6 for the kobject.h file.
      
        It fixes a reported oops if CONFIG_HOTPLUG is disabled.  It's been in
        the linux-next tree for a while now.

      vfs: make O_PATH file descriptors usable for 'fstat()' · 55815f70
      Linus Torvalds authored
      We already use them for openat() and friends, but fstat() also wants to
      be able to use O_PATH file descriptors.  This should make it more
      directly comparable to the O_SEARCH of Solaris.
      
      Note that you could already do the same thing with "fstatat()" and an
      empty path, but just doing "fstat()" directly is simpler and faster, so
      there is no reason not to just allow it directly.
      
      See also commit 332a2e12, which did the same thing for fchdir, for
      the same reasons.
