[Kernel-packages] [Bug 1744173] Re: artful: rfi-flush: Switch to new linear fallback flush
Hi Breno, Sorry for the late reply. Regarding Xenial, we updated the kernel to a later upstream stable version since you posted the patches. 4.4.0-123.147 from -proposed should be in sync with 4.4.128 now and your patches don't apply cleanly any longer. When updating to 4.4.117 we reverted a bunch of SAUCE rfi-flush patches and replaced them with the upstream versions. Is there a possibility that your patches are no longer required with those updates?

[Kernel-packages] [Bug 1744173] Re: artful: rfi-flush: Switch to new linear fallback flush
hi Joseph, I tested on both versions and the kernel solves the problem: == Xenial == # uname -a Linux 1604 4.4.0-116-generic #140~lp1744174 SMP Tue Mar 6 14:15:54 UTC 2018 ppc64le ppc64le ppc64le GNU/Linux == Artful == # uname -a Linux 1710 4.13.0-36-generic #40~lp1744173 SMP Tue Mar 6 14:17:17 UTC 2018 ppc64le ppc64le ppc64le GNU/Linux The patches can make the official tree in my opinion. PS: You look the kernel version, it has the extesion ~lpXX, one refers to lp1744173 and the other one to lp1744174, but I understand it was a typo, and both refers to the same fix (lp1744173), right?
