Subject: [GIT PULL] kdbus cleanups for 4.2

Hi Greg

This contains a bunch of fixes, optimizations and cleanups since v4.0. It is
based on your 'kdbus' branch and was tested for several weeks.
I have some more patches pending, mainly metadata rework for 4.2. However, this
breaks backwards compat so I want to get everything else out first.

Thanks
David

  kdbus: no need to ref current->mm (2015-06-03 18:50:21 +0200)

----------------------------------------------------------------
kdbus cleanups since 4.1 for Greg

 * Several cleanups to reduce locking in metadata collection and connection
   management.

 * Translate CAPS between namespaces just like ./security/commoncaps.c does.
   Previously we just dropped CAPS on namespace borders, now we translate them
   according to the upstream translation rules.

 * IdAdd / IdRemove notifications are now forwarded to everyone. This fixes
   issues with sandboxes which want to track API users, but cant if they don't
   get those notifications.

 * Drop kdbus_meta_attach_mask module parameter. It was a workaround which was
   never used by anyone. Drop it and lets figure out the remaining issues
   people disagree on properly, without any hacks.

 * Miscellaneous build fixes.
