[Xen-devel] [PATCH] [ACM] Add Hypervisor Call Macro

[Reiner Sailer <sailer@xxxxxxxxxx>]

This patch adds a hypervisor call macro to the linux kernel; it 
completes the alignment of the ACM call interface with the other Xen 
hypervisor call interfaces. This macro is used to call from the a guest 
kernel directly into the ACM hypervisor module.
