Hi Andrew, Today's linux-next merge of the akpm-current tree got a conflict in kernel/kexec.c between commit 011e4b02f1da ("powerpc, kexec: Fix "Processor X is stuck" issue during kexec from ST mode") from Linus' tree and commit 51950fcb6d27 ("kernel/kexec.c: convert printk to pr_foo()") from the akpm-current tree. I fixed it up (see below) and can carry the fix as necessary (no action is required). -- Cheers, Stephen Rothwell sfr@canb.auug.org.au diff --cc kernel/kexec.c index 28c57069ef68,bf0b929e7f94..000000000000 --- a/kernel/kexec.c +++ b/kernel/kexec.c @@@ -1683,15 -1679,7 +1679,15 @@@ int kernel_kexec(void kexec_in_progress = true; kernel_restart_prepare(NULL); migrate_to_reboot_cpu(); + + /* + * migrate_to_reboot_cpu() disables CPU hotplug assuming that + * no further code needs to use CPU hotplug (which is true in + * the reboot case).
