Rather than requiring architectures that use gpiolib but don't have any need to define anything custom to copy an asm/gpio.h, merge this code into the asm-generic/gpio.h. We add ifdef checks so that arches can still override things while using the asm-generic/gpio.h, but on a more fine grained per-func approach.
I've compile tested these guys (with & without GPIOLIB), but don't have the hardware to boot: - alpha defconfig - arm: all defconfigs - blackfin defconfig - ia64 defconfig - m68k: multi & m5208evb defconfig - mips: ar7 & ath79 & bcm47xx & bcm63xx & ip22 defconfig - powerpc: mpc85xx & ppc64 defconfig - sh: kfr2r09 defconfig - sparc defconfig - x86_64 defconfig I don't have any toolchains for avr32, microblaze, openrisc, unicore32, or xtensa. So they lose :x.
