[RFA][PATCH 0/2] ftrace: Fix arch issues with function graph trampoline

From: Steven Rostedt

H. Peter Anvin,

It was reported to me that my for-next branch broke other archs.
This patch series makes the ftrace graph trampoline an opt-in feature,
as it may require some arch changes to make it work. X86 did not
require changes, but now that it is an opt in, x86 needs to do so
to get this feature.

Can you give me your Acked-by on patch 2?

ftrace: Allow archs to specify if they need a separate function graph trampoline
ftrace/x86: Have function graph tracer use its own trampoline
