This patch enables EFI usage under Xen dom0. Standard EFI Linux Kernel infrastructure cannot be used because it requires direct access to EFI data and code. However, in dom0 case it is not possible because above mentioned EFI stuff is fully owned and controlled by Xen hypervisor. In this case all calls from dom0 to EFI must be requested via special hypercall which in turn executes relevant EFI code in behalf of dom0. When dom0 kernel boots it checks for EFI availability on a machine. If it is detected then artificial EFI system table is filled. Native EFI callas are replaced by functions which mimics them by calling relevant hypercall. Later pointer to EFI system table is passed to standard EFI machinery and it continues EFI subsystem initialization taking into account that there is no direct access to EFI boot services, runtime, tables, structures, etc. After that system runs as usual. This patch is based on Jan Beulich and Tang Liang work.
