2010-07-08x86: Export the symbol ms_hypervKy Srinivasan
This is needed so that the staging hyperv can properly access this symbol. Signed-off-by: K. Y. Srinivasan <ksrinivasan@novell.com> Acked-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-05-09x86, hypervisor: add missing <linux/module.h>H. Peter Anvin
EXPORT_SYMBOL() needs <linux/module.h> to be included; fixes modular builds of the VMware balloon driver, and any future modular drivers which depends on the hypervisor.

2010-05-09x86, hypervisor: Export the x86_hyper* symbolsH. Peter Anvin
Export x86_hyper and the related specific structures, allowing for hypervisor identification by modules. Signed-off-by: H.

2010-05-07x86: Clean up the hypervisor layerH. Peter Anvin
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.

2010-05-07x86, HyperV: fix up the license to mshyperv.cGreg Kroah-Hartman
This should have been GPLv2 only, we cut and pasted from the wrong file originally, sorry. Also removed some unneeded boilerplate license code, we all know where to find the GPLv2, and that there's no warranty as that is implicit from the license.

2010-05-06x86: Detect running on a Microsoft HyperV systemKy Srinivasan
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.
