Subject: x86/fpu/debug: Remove unused 'x86_fpu_state' and 'x86_fpu_deactivate_state' tracepoints
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.
