Subject: [PATCH] powerpc64/ftrace: Include ftrace.h needed for enable/disable
 calls

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")
