Subject: [PATCH 4.19 069/139] KVM: VMX: re-add ple_gap module parameter

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

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

From: Luiz Capitulino <lcapitulino@...hat.com>

commit a87c99e61236ba8ca962ce97a19fab5ebd588d35 upstream.

Apparently, the ple_gap parameter was accidentally removed
by commit c8e88717cfc6b36bedea22368d97667446318291. Add it
back.
