Yeah, you are right, will put them under CONFIG_MMU. I thought making GENERIC_IOREMAP depend MMU in Kconfig will contain that. But people can manually set the Kconfig item freely. Thanks for pointing it out. diff --git a/arch/sh/Kconfig b/arch/sh/Kconfig index 5f220e903e5a..b63ad4698cf8 100644 --- a/arch/sh/Kconfig +++ b/arch/sh/Kconfig @@ -25,6 +25,7 @@ config SUPERH select GENERIC_SCHED_CLOCK select GENERIC_SMP_IDLE_THREAD select GUP_GET_PTE_LOW_HIGH if X2TLB + select GENERIC_IOREMAP if MMU >

Oops, I thought the cross compilig can be done on any platform. Since I need test arm64 patch in this patchset, so didn't get x86 system to reproduce. Didn't realize lkp has an assumption. I will get a x86 system to test this.
