Hi Andrew,
After merging the akpm-current tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

Caused by commits
bbd24d7bb4cd ("powerpc: implement kexec_file_load")
325f517062cb ("powerpc: ima: send the kexec buffer to the next kernel")
I applied the following fix patches for today:

This is a new version of the kexec system call. This call is
file based and takes in file descriptors as system call arguments
