2010-05-07	x86: Clean up the hypervisor layer	H. Peter Anvin	1	-4/+11
	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.

2010-05-06	x86: Detect running on a Microsoft HyperV system	Ky Srinivasan	1	-0/+7
	This patch integrates HyperV detection within the framework currently used by VmWare. With this patch, we can avoid having to replicate the HyperV detection code in each of the Microsoft HyperV drivers. Reworked and tweaked by Greg K-H to build properly. Signed-off-by: K. Y.
