      Pull ARM Renesas SoC cleanup, refactoring and more SMP support from Kevin Hilman:
       "Lots of cleanup and refactoring and some SMP additions for Renesas
        platforms.  Due to some inter-dependencies with other arm-soc
        branches, this Renesas stuff was separated out for sending after the
        other branches were merged.
      
        Highlights:
         - remove unused board support and cleanup of unused headers
         - refactoring of init and device registration
         - simplify IRQ initialization"

      Pull tracing updates from Steven Rostedt:
       "Not much changes for the 3.12 merge window.  The major tracing changes
        are still in flux, and will have to wait for 3.13.
      
        The changes for 3.12 are mostly clean ups and minor fixes.
      
        H Peter Anvin added a check to x86_32 static function tracing that
        helps a small segment of the kernel community.
      
        Oleg Nesterov had a few changes from 3.11, but were mostly clean ups
        and not worth pushing in the -rc time frame.
      
        Li Zefan had small clean up with annotating a raw_init with __init.
      
        I fixed a slight race in updating function callbacks, but the race is
        so small and the bug that happens when it occurs is so minor it's not
        even worth pushing to stable.
      
        The only real enhancement is from Alexander Z Lam that made the
        tracing_cpumask work for trace buffer instances, instead of them all
        sharing a global cpumask"

      clk: only call get_parent if there is one · 12d29886
      Alex Elder authored
      
      
      In __clk_init(), after a clock is mostly initialized, a scan is done
      of the orphan clocks to see if the clock being registered is the
      parent of any of them.
      
      This code assumes that any clock that provides a get_parent method
      actually has at least one parent, and that's not a valid assumption.
      
      As a result, an orphan clock with no parent can return *something*
      as the parent index, and that value is blindly used to dereference
      the orphan's parent_names[] array (which will be ZERO_SIZE_PTR or
      NULL).
      
      Fix this by ensuring get_parent is only called for orphans with at
      least one parent.

      direct-io: Use return from cmpxchg to decide of assignment happened · 45150c43
      Olof Johansson authored
      
      
      Not using the return value can in the generic case be racy, so it's
      in general good practice to check the return value instead.
      
      This also resolved the warning caused on ARM and other architectures:

      vfs: fix dentry RCU to refcounting possibly sleeping dput() · e5c832d5
      Linus Torvalds authored
      
      
      This is the fix that the last two commits indirectly led up to - making
      sure that we don't call dput() in a bad context on the dentries we've
      looked up in RCU mode after the sequence count validation fails.
      
      This basically expands d_rcu_to_refcount() into the callers, and then
      fixes the callers to delay the dput() in the failure case until _after_
      we've dropped all locks and are no longer in an RCU-locked region.
      
      The case of 'complete_walk()' was trivial, since its failure case did
      the unlock_rcu_walk() directly after the call to d_rcu_to_refcount(),
      and as such that is just a pure expansion of the function with a trivial
      movement of the resulting dput() to after 'unlock_rcu_walk()'.
      
      In contrast, the unlazy_walk() case was much more complicated, because
      not only does convert two different dentries from RCU to be reference
      counted, but it used to not call unlock_rcu_walk() at all, and instead
      just returned an error and let the caller clean everything up in
      "terminate_walk()".
      
      Happily, one of the dentries in question (called "parent" inside
      unlazy_walk()) is the dentry of "nd->path", which terminate_walk() wants
      a refcount to anyway for the non-RCU case.
      
      So what the new and improved unlazy_walk() does is to first turn that
      dentry into a refcounted one, and once that is set up, the error cases
      can continue to use the terminate_walk() helper for cleanup, but for the
      non-RCU case.  Which makes it possible to drop out of RCU mode if we
      actually hit the sequence number failure case.

      vfs: use lockred "dead" flag to mark unrecoverably dead dentries · 0d98439e
      Linus Torvalds authored
      This simplifies the RCU to refcounting code in particular.
      
      I was originally intending to leave this for later, but walking through
      all the dput() logic (see previous commit), I realized that the dput()
      "might_sleep()" check was misleadingly weak.  And I removed it as
      misleading, both for performance profiling and for debugging.
      
      However, the might_sleep() debugging case is actually true: the final
      dput() can indeed sleep, if the inode of the dentry that you are
      releasing ends up sleeping at iput time (see dentry_iput()).  So the
      problem with the might_sleep() in dput() wasn't that it wasn't true, it
      was that it wasn't actually testing and triggering on the interesting
      case.
      
      In particular, just about *any* dput() can indeed sleep, if you happen
      to race with another thread deleting the file in question, and you then
      lose the race to the be the last dput() for that file.  But because it's
      a very rare race, the debugging code would never trigger it in practice.
      
      Why is this problematic? The new d_rcu_to_refcount() (see commit
      15570086
      
      : "vfs: reimplement d_rcu_to_refcount() using
      lockref_get_or_lock()") does a dput() for the failure case, and it does
      it under the RCU lock.  So potentially sleeping really is a bug.
      
      But there's no way I'm going to fix this with the previous complicated
      "lockref_get_or_lock()" interface.  And rather than revert to the old
      and crufty nested dentry locking code (which did get this right by
      delaying the reference count updates until they were verified to be
      safe), let's make forward progress.

      vfs: reorganize dput() memory accesses · 8aab6a27
      Linus Torvalds authored
      
      
      This is me being a bit OCD after all the dentry optimization work this
      merge window: profiles end up showing 'dput()' as a rather expensive
      operation, and there were two unrelated bad reasons for that.
      
      The first reason was reading d_lockref.count for debugging purposes,
      which touches the lockref cacheline (for reads) before really need to.
      More importantly, the debugging test in question is _wrong_, and has
      hidden bugs.  It's true that we can only sleep when the count goes down
      to zero, but the test as-is hides the much more subtle bug that happens
      if we race with somebody else deleting the file.
      
      Anyway we _will_ touch that cacheline, but let's do it for a write and
      in the right routine (ie in "lockref_put_or_lock()") which annotates the
      costs better.  So remove the misleading debug code.
      
      The other was an unnecessary access to the cacheline that contains the
      d_lru list, just to check whether we already were on the LRU list or
      not.  This is exactly what we have d_flags for, so that we can avoid
      touching extra cache lines for the common case.  So just add another bit
      for "is this dentry on the LRU".
      
      Finally, mark the tests properly likely/unlikely, so that the common
      fast-paths are dense in the instruction stream.
      
      This makes the profiles look much saner.

      lockref: add ability to mark lockrefs "dead" · e7d33bb5
      Linus Torvalds authored
      
      
      The only actual current lockref user (dcache) uses zero reference counts
      even for perfectly live dentries, because it's a cache: there may not be
      any users, but that doesn't mean that we want to throw away the dentry.
      
      At the same time, the dentry cache does have a notion of a truly "dead"
      dentry that we must not even increment the reference count of, because
      we have pruned it and it is not valid.
      
      Currently that distinction is not visible in the lockref itself, and the
      dentry cache validation uses "lockref_get_or_lock()" to either get a new
      reference to a dentry that already had existing references (and thus
      cannot be dead), or get the dentry lock so that we can then verify the
      dentry and increment the reference count under the lock if that
      verification was successful.
      
      That's all somewhat complicated.
      
      This adds the concept of being "dead" to the lockref itself, by simply
      using a count that is negative.  This allows a usage scenario where we
      can increment the refcount of a dentry without having to validate it,
      and pushing the special "we killed it" case into the lockref code.
      
      The dentry code itself doesn't actually use this yet, and it's probably
      too late in the merge window to do that code (the dentry_kill() code
      with its "should I decrement the count" logic really is pretty complex
      code), but let's introduce the concept at the lockref level now.

      NFSv4: use mach cred for SECINFO_NO_NAME w/ integrity · b1b3e136
      Weston Andros Adamson authored
      Commit 97431204
      
       introduced a regression
      that causes SECINFO_NO_NAME to fail without sending an RPC if:
      
       1) the nfs_client's rpc_client is using krb5i/p (now tried by default)
       2) the current user doesn't have valid kerberos credentials
      
      This situation is quite common - as of now a sec=sys mount would use
      krb5i for the nfs_client's rpc_client and a user would hardly be faulted
      for not having run kinit.
      
      The solution is to use the machine cred when trying to use an integrity
      protected auth flavor for SECINFO_NO_NAME.
      
      Older servers may not support using the machine cred or an integrity
      protected auth flavor for SECINFO_NO_NAME in every circumstance, so we fall
      back to using the user's cred and the filesystem's auth flavor in this case.
      
      We run into another problem when running against linux nfs servers -
      they return NFS4ERR_WRONGSEC when using integrity auth flavor (unless the
      mount is also that flavor) even though that is not a valid error for
      SECINFO*.  Even though it's against spec, handle WRONGSEC errors on
      SECINFO_NO_NAME by falling back to using the user cred and the
      filesystem's auth flavor.
