4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Luke Dashjr <luke@xxxxxxxxxx>
commit d6ee76d3d37d156c479348821574b6f99d6472a1 upstream.
this_cpu_disable_ftrace and this_cpu_enable_ftrace are inlines in
ftrace.h Without it included, the build fails.
Fixes: a4bc64d305af ("powerpc64/ftrace: Disable ftrace during kvm entry/exit")
