Gmane

Subject: 2.6.31.4

Stefan and I did a review of the 2.6.31.4 stable updates.  Most appear
to either be fairly important fixes in core code, or small but very self
contained updates for drivers and/or quirks and low risk.

There are three which could sensibly be ignored, the integrity ones are
high end server style things, and a third which is actually a functional
noop:

    ima: ecryptfs fix imbalance message
    IMA: open new file for read
    tun: Return -EINVAL if neither IFF_TUN nor IFF_TAP is set.

There is one which is definatly an ABI bumper, though the interface
change is not in the core interfaces and likely could be ignored:

    tracing: correct module boundaries for ftrace_release

Overall it seems sensible to take all of these.  Some notes we took on
each is below.
