From 3e90d28649a49d52673957e5f030c7c1c010d8a8 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Thu, 2 Feb 2017 15:49:42 +0100 Subject: [PATCH] compat.h: drop COMPAT_HANDLE_PARAM() The need for 8844ed299a ("x86/dmop: Fix compat_dm_op() ABI") has made clear that its presence is actively dangerous. At the hypercall entry points XEN_GUEST_HANDLE_PARAM() should be used anyway (regardless of whether these are native or compat entry points), and passing around handles internally shouldn't use their compat representation either.
