2009-09-16m68knommu: use general interrupt controller for ColdFire 520x familyGreg Ungerer
Create general interrupt controller code for the ColdFire 520x family, that does proper masking and unmasking of interrupts. With this in place some of the driver hacks in place to support ColdFire interrupts can finally go away. Within the ColdFire family there is a variety of different interrupt controllers in use. Some are used on multiple parts, some on only one. There is quite some differences in some varients, so much so that common code for all ColdFire parts would be impossible. This commit introduces code to support one of the newer interrupt controllers in the ColdFire 5208 and 5207 parts. It has very simple mask and unmask operations, so is one of the easiest to support.

Commit 5fd29d6ccbc98884569d6f3105aeca70858b3e0f ("printk: clean up handling of log-levels and newlines") changed printk semantics. printk lines with multiple KERN_<level> prefixes are no longer emitted as before the patch. <level> is now included in the output on each additional use.

2009-06-16mm: consolidate init_mm definitionAlexey Dobriyan
* 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.

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