When attempting to load a livepatch module, I got the following error: module_64: patch_module: Expect noop after relocate, got 3c820000 The error was triggered by the following code in unregister_netdevice_queue(): 14c: 00 00 00 48 b 14c <unregister_netdevice_queue+0x14c> 14c: R_PPC64_REL24 net_set_todo 150: 00 00 82 3c addis r4,r2,0 GCC didn't insert a nop after the branch to net_set_todo() because it's a sibling call, so it never returns. The nop isn't needed after the branch in that case. ** Attachment added: "[2/3] powerpc/modules: Don't try to restore r2 after a sibling call" https://bugs.launchpad.net/bugs/1741992/+attachment/5033176/+files/0002-powerpc-modules-Don-t-try-to-restore-r2-after-a-sibl.patch -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1741992 Title: kpatch - Add livepatch hook support for ppc64le Status in The Ubuntu-power-systems project: Triaged Status in linux package in Ubuntu: New Bug description: kpatch is a Linux dynamic kernel patching infrastructure which allows you to patch a running kernel without rebooting or restarting any processes. It enables sysadmins to apply critical security patches to the kernel immediately, without having to wait for long-running tasks to complete, for users to log off, or for scheduled reboot windows.
