A later change needs the same "park this worker forever" primitive on the runtime service timeout path, so factor the loop into a shared efi_rts_park_worker() and call it from the x86 page-fault handler.

refactor coding style in several drivers - use correct endianess translation in gpio-pcf85x - add wake-up interrupt support to gpio-mvebu - apply initial value in direction output setter in gpio-by-pinctrl Misc: -
