I suspect that this is caused by the changes to init/Kconfig:
diff --git a/init/Kconfig b/init/Kconfig
index be8b7f5..a05f843 100644
--- a/init/Kconfig
+++ b/init/Kconfig
@@ -326,6 +326,9 @@ source "kernel/time/Kconfig"
menu "CPU/Task time and stats accounting"
+config VIRT_CPU_ACCOUNTING
+ bool

choice
prompt "Cputime accounting"
default TICK_CPU_ACCOUNTING if !PPC64
The next line of context is:
default VIRT_CPU_ACCOUNTING if PPC64
Which may have needed changing as well? Indeed, changing that to
VIRT_CPU_ACCOUNTING_NATIVE restores the old defaults.
