From 7f95104d91ccfb26f802feb5300838b41bc5fbb1 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Fri, 5 Jul 2019 17:42:16 +0200 Subject: efi_loader: detach runtime in ExitBootServices() Linux can be called with a command line parameter efi=novamap, cf. commit 4e46c2a95621 ("efi/arm/arm64: Allow SetVirtualAddressMap() to be omitted"). In this case SetVirtualAddressMap() is not called after ExitBootServices(). OpenBSD 32bit does not call SetVirtualAddressMap() either. Runtime services must be set to an implementation supported at runtime in ExitBootServices().
