Thank you James. I will summaries the information gathered from the yesterday's/today's discussion and add it to the cover letter together with ARM64 tag. I think, the patch series makes sense for ARM64 only, unless there are other platforms that disable caching/MMU during relocation. Thank you, Pasha > > > Thanks, > > James
