common: drop all the 4.9 kernel metadata
None of the BSPs are currently based on the 4.9 kernel so drop the common metadata as well. Signed-off-by: Awais Belal <awais_belal@mentor.com>

-Subject: [PATCH 22/42] x86/entry/64: Push extra regs right away
-
-(cherry picked from commit d1f7732009e0549eedf8ea1db948dc37be77fd46)
-
-With the fast path removed there is no point in splitting the push of the
-normal and the extra register set. Just push the extra regs right away.
