#     powerpc/code-patching: Replace patch_instruction() by ppc_inst_write() in selftests
#     
#     The purpose of selftests is to check that instructions are
#     properly formed. Not to check that they properly run.
#     
#     For that test it uses normal memory, not special test
#     memory.
#     
#     In preparation of a future patch enforcing patch_instruction()
#     to be used only on valid text areas, implement a ppc_inst_write()
#     instruction which is the complement of ppc_inst_read(). This
#     new function writes the formated instruction in valid kernel
#     memory and doesn't bother about icache.
