Well, I list the ARCHs related to the change file, do not include cris,ia64,mn10300
and openrisc, which ioremap is not the same as ioremap_nocache, as discussed in cover
letter. So please let me know if I need update the comment.

change_file ARCH
drivers/gpio/gpio-ath79.c | 3 +-- mips
drivers/gpio/gpio-em.c | 6 ++---- arm
drivers/gpio/gpio-htc-egpio.c | 4 ++-- arm
drivers/gpio/gpio-xgene.c | 3 +-- arm64

Thanks
