For further context, the corresponding ppc64-enablement patch is was just sent by Christophe: https://lkml.kernel.org/r/afaec81a551ef15345cb7d7563b3fac3d7041c3a.1614868445.git.christophe.le...@csgroup.eu But there is no strict dependency between the patches, only that the stack traces that KFENCE prints aren't as pretty without the ARCH_FUNC_PREFIX patch. So it should be fine to take them through different trees, as long as they both make the next merge window. Thanks, -- Marco
