We believe the LTS is the base kernel for android/lsk, so the fixing patches should get it first and then merge to other tree. > >> Any comments are appreciated! > > You need to start versioning this changeset, as I have no idea if this > is the "latest" one or not, right?> > Or have you not sent out this patchset before? How does this interact > with the "spectre" patches? Or am I totally confused here? It is the first patchset for meltdown. Yes, I will resent this patchset with versioning after the renesas board booting fixed. The meltdown and spectre is 2 different bugs, the fixing patchset are isolated each other. So I did the backport as 2 different patchset. And merging them together is relative simple. I will comming with a merge patch next time, after the meltdown patchset ready.(the kernelci didn't works well in recent days) Thanks Alex
