Was the immediately previous linux-next behaving correctly? If so, nothing has changed in the ARM32 kernel tree, so this must be someone else's issue - code that someone else has pushed into linux-next. It looks to me like someone is walking the page tables incorrectly, somewhere buried in handle_mm_fault(), because the PTE pointer is in the upper-2k of a 4k page, which is most definitely illegal on arm32. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last! _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
