Hello Hauke, There are two patches, which solves problem with undefined "Abort": https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/comm it/?id=7c2c11b208be09c156573fc0076b7b3646e05219 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/comm it/?id=dc8635b78cd8669c37e230058d18c33af7451ab1 These patches are applied in Linux 4.15 ver. I have placed these patches in target/linux/generic/backport-4.14 and build finished without errors. I expect these patches will be backported in upstream 4.14 branch anytime soon. Until these patches are accepted should I add them with separate patch or should I add them in patch-series with kernel version update for archs38? Best regards, Evgeniy Didin
