[PATCH v5 04/21] powerpc: Use a macro for creating instructions from u32s
Jordan Niethe
jniethe5 at gmail.com
Mon Apr 6 18:09:19 AEST 2020
In preparation for instructions having a more complex data type start
using a macro, ppc_inst(), for making an instruction out of a u32. A
macro is used so that instructions can be used as initializer elements.
Currently this does nothing, but it will allow for creating a data type
that can represent prefixed instructions.
Signed-off-by: Jordan Niethe <jniethe5 at gmail.com>
---
v4: New to series
v5: - Rename PPC_INST() -> ppc_inst().
- Use on epapr_paravirt.c, kgdb.c
