- fix a regression and add hotplug memory to the zone movable again
- add ignore defines for the pkey system calls
- fix the ouput of the merged stack tracer
- replace printk with pr_cont in arch/s390 where appropriate
- remove the arch specific return_address function again
- ignore reserved channel paths at boot time
- add a missing hugetlb_bad_size call to the arch backend"
