Hi Paul, After merging the kvm-ppc tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: arch/powerpc/kvm/book3s_xive.c: In function 'xive_debugfs_init': arch/powerpc/kvm/book3s_xive.c:1852:52: error: 'powerpc_debugfs_root' undeclared (first use in this function) xive->dentry = debugfs_create_file(name, S_IRUGO, powerpc_debugfs_root, ^ Caused by commit 5af50993850a ("KVM: PPC: Book3S HV: Native usage of the XIVE interrupt controller") interacting with commit 7644d5819cf8 ("powerpc: Create asm/debugfs.h and move powerpc_debugfs_root there") from the powerpc tree. I have added the following merge fix patch. From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx> Date: Fri, 28 Apr 2017 14:28:17 +1000 Subject: [PATCH] powerpc: merge fix for powerpc_debugfs_root move.
