Moreover, the pci_iounmap function was not defined in the io.h header file if the CONFIG_PCI symbol is not set, but it should since MIPS is not using CONFIG_GENERIC_IOMAP.

Anything ever build in the MIPS empire is either MIPS I or at least contains MIPS I. If it's running Linux, that is. So there is little point in having cpu_has_mips_1 because it will always evaluate as true - though usually only at runtime. Thus there is no point in having the MIPS_CPU_ISA_I ISA flag, so get rid of it. Little complication: traps.c was using a test for a pure MIPS I ISA as a test for an R3000-style cp0. To deal with that, use a check for cpu_has_3kex or cpu_has_4kex instead. cpu_has_3kex is a new macro. At the moment its default implementation is !cpu_has_4kex but this may eventually change if Linux is ever going to support the oddball MIPS processors R6000 and R8000 so users of either of these macros should not make any assumptions.

They are only built if CONFIG_HAVE_GPIO_LIB is set. But the Kconfig symbol HAVE_GPIO_LIB was already removed in v2.6.27, see commit 7444a72eff ("gpiolib: allow user-selection"). So these drivers were never buildable. Perhaps no-one noticed because there are no in tree users of msp71xx_init_gpio() and msp71xx_init_gpio_extended(). Anyhow, these drivers can safely be removed.
