From c00a280a8efa4dc077596cf646bd50cbd13db3c8 Mon Sep 17 00:00:00 2001 From: Juergen Gross Date: Tue, 28 Aug 2018 09:40:21 +0200 Subject: x86/paravirt: Introduce new config option PARAVIRT_XXL A large amount of paravirt ops is used by Xen PV guests only. Add a new config option PARAVIRT_XXL which is selected by XEN_PV. Later we can put the Xen PV only paravirt ops under the PARAVIRT_XXL umbrella. Since irq related paravirt ops are used only by VSMP and Xen PV, let VSMP select PARAVIRT_XXL, too, in order to enable moving the irq ops under PARAVIRT_XXL.
