I sent a patch some time ago, got an Ack, but the patch is not yet in tty-next.

I don't get this on my machine. Maybe another misoptimization by older gcc versions?

Sent a patch the other day, got an Ack.

I have a patch for this, need to resend a new version to avoid a regression on UML.

It's GCC 4.9 and 5.1..

Ok, I found it now. My series has one patch to disable ARCH_HAS_GCOV_PROFILE_ALL on ARM. Without that symbol, I get the same thing on all compiler versions on allmodconfig, and then I also get these:

Just when I thought I had all randconfig warnings covered...
There are probably others that are not active with allmodconfig but with some other randconfig build with ARCH_HAS_GCOV_PROFILE_ALL enabled.
