[PATCH 4.14 012/159] x86/fpu/debug: Remove unused x86_fpu_state and x86_fpu_deactivate_state tracepoints

[Greg Kroah-Hartman]

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Steven Rostedt (VMware) <rostedt@xxxxxxxxxxx>

commit 127a1bea40f7f2a36bc7207ea4d51bb6b4e936fa upstream.

Commit:

  d1898b733619 ("x86/fpu: Add tracepoints to dump FPU state at key points")

... added the 'x86_fpu_state' and 'x86_fpu_deactivate_state' trace points,
but never used them. Today they are still not used. As they take up
and waste memory, remove them.
