[PATCH 4.18 036/145] powerpc64/ftrace: Include ftrace.h needed for enable/disable calls

[Greg Kroah-Hartman]

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")
