This is because my kexec_file_load patches lost a few hunks.
The patch below fixes the issue.
Many of the problems with this patch series stem from the fact that it
conflicted with the s/CONFIG_WORD_SIZE/BITS/ change that went into v4.9-rc1.
I will post a new version rebased on top of v4.9-rc1, this should get things
back on track. I'll have them ready by tomorrow.
Thank you for your patience.
