From e08cae4181af9483b04ecfac48f01c8e5a5f27bf Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Fri, 7 May 2010 16:57:28 -0700 Subject: x86: Clean up the hypervisor layer Clean up the hypervisor layer and the hypervisor drivers, using an ops structure instead of an enumeration with if statements. The identity of the hypervisor, if needed, can be tested by testing the pointer value in x86_hyper. The MS-HyperV private state is moved into a normal global variable (it's per-system state, not per-CPU state). Being a normal bss variable, it will be left at all zero on non-HyperV platforms, and so can generally be tested for HyperV-specific features without additional qualification. Signed-off-by: H.
