[POWERPC] clean up pseries hcall interfaces
Our pseries hcall interfaces are out of control: plpar_hcall_norets plpar_hcall plpar_hcall_8arg_2ret plpar_hcall_4out plpar_hcall_7arg_7ret plpar_hcall_9arg_9ret Create 3 interfaces to cover all cases: plpar_hcall_norets: 7 arguments no returns plpar_hcall: 6 arguments 4 returns plpar_hcall9: 9 arguments 9 returns There are only 2 cases in the kernel that need plpar_hcall9, hopefully we can keep it that way. Pass in a buffer to stash return parameters so we avoid the &dummy1, &dummy2 madness. Signed-off-by: Anton Blanchard <anton@samba.org> -- Signed-off-by: Paul Mackerras <paulus@samba.org>
