This is a note to let you know that I've just added the patch titled
kaiser: fix intel_bts perf crashesto the 4.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git%3Ba=su...
The filename of the patch is: kaiser-fix-intel_bts-perf-crashes.patch and it can be found in the queue-4.4 subdirectory.
If you, or anyone else, feels it should not be added to the stable tree, please let stable@vger.kernel.org know about it.
I thought that to get into stable the patch had to be in upstream first.
As far as I know, there is no fix for this particular problem (BTS disabled due to KPTI caused crashes) upstream.
Really? This is a reported issue in 4.15? I haven't seen that report anywhere, do you have a pointer to it?
The 4.4 and 4.9 backports do have odd one-off patches that are not in 4.14 and newer due to the way the backports were done, so they will diverge. But they should not diverge in bugfixes :)
