[ANNOUNCE] 4.6.7-rt12

Dear RT folks!

I'm pleased to announce the v4.6.7-rt12 patch set.

Changes since v4.6.7-rt11:

  - The update to v4.6.7-rt11 introduced a performance regression
    especially visible when compiling a kernel on /dev/shm. It is fixed
    by invoking less often the "chill" function. Reported by Joakim

  - We had a fix in v3.12.8-rt11 for ip_send_unicast_reply() which I
    dropped in v3.18.8 based -RT due code change and I assumed the need
    for extra serialization is no longer required. As it turns out it is
    still required :)

  - While looking around a similar serialisation might be required in
    icmp_sk(). No crash has been observed, this is just precaution.

Known issues
	- CPU hotplug got a little better but can deadlock.
