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).
