#     powerpc: Provide initial documentation for PAPR hcalls
#     
#     This doc patch provides an initial description of the hcall op-codes
#     that are used by Linux kernel running as a guest (LPAR) on top of
#     PowerVM or any other sPAPR compliant hyper-visor (e.g qemu).
#     
#     Apart from documenting the hcalls the doc-patch also provides a
#     rudimentary overview of how hcall ABI, how they are issued with the
#     Linux kernel and how information/control flows between the guest and
#     hypervisor.
