ppc_md.iommu_save() is not set anymore by any platform after commitc40785ad30("powerpc/dart: Use a cachable DART"). So iommu_save() has become a nop and can be removed. ppc_md.show_percpuinfo() is not set anymore by any platform after commit4350147a81("[PATCH] ppc64: SMU based macs cpufreq support"). Last users of ppc_md.rtc_read_val() and ppc_md.rtc_write_val() were removed by commit0f03a43b8f("[POWERPC] Remove todc code from ARCH=powerpc") Last user of kgdb_map_scc() was removed by commit17ce452f7e("kgdb, powerpc: arch specific powerpc kgdb support"). ppc.machine_kexec_prepare() has not been used since commit8ee3e0d696("powerpc: Remove the main legacy iSerie platform code"). This allows the removal of machine_kexec_prepare() and the rename of default_machine_kexec_prepare() into machine_kexec_prepare() Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> Reviewed-by: Daniel Axtens <dja@axtens.net> [mpe: Drop prototype for default_machine_kexec_prepare() as noted by dja] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/24d4ca0ada683c9436a5f812a7aeb0a1362afa2b.1630398606.git.christophe.leroy@csgroup.eu
