bb1f17b037 mm: consolidate init_mm definition
* create mm/init-mm.c, move init_mm there
* remove INIT_MM, initialize init_mm with C99 initializer
* unexport init_mm on all arches:

  init_mm is already unexported on x86.

  One strange place is some OMAP driver (drivers/video/omap/) which
  won't build modular, but it's already wants get_vm_area() export.
  Somebody should look there.

ec40f95db7 m68knommu: fix DMA support for ColdFire

core use it, the rest have dedicated DMA engines). The code support is

592578a1dd m68knommu: Fixed GPIO pin initialization for CONFIG_M5271 FEC.
This processor only have one FEC and its MDIO pins are
located at a different offset than the code used for
the current CONFIG_M527x.

Tesed on M5271EVB eval platform.
Without this patch the FEC driver will report no PHY attached
if the bootloader does not pre-initialize the PAR_FECI2C GPIO register.

address of the UIVR register is wrong, it needs to be offset into the
