[PATCH 5.4 07/51] x86/cpufeatures: Move RETPOLINE flags to word 11

[Greg Kroah-Hartman]

From: Peter Zijlstra <peterz@xxxxxxxxxxxxx>

commit a883d624aed463c84c22596006e5a96f5b44db31 upstream.

In order to extend the RETPOLINE features to 4, move them to word 11
where there is still room. This mostly keeps DISABLE_RETPOLINE
simple.
