However upcoming cleanups in the ARM architecture require that some fixed locations in the vmalloc area be reserved also very early. The name "vm_area_register_early" would have been a good name for the reservation part without the allocation. Since it is already in use with different semantics, let's create vm_area_add_early() instead. Both vm_area_register_early() and vm_area_add_early() can be used together meaning that the former is now implemented using the later where it is ensured that no conflicting areas are added, but no attempt is made to make the allocation scheme in vm_area_register_early() more sophisticated. After all, you must know what you're doing when using those functions.

This allows for VMALLOC_END to be identical across all machines. The value for VMALLOC_END is now set to 0xff000000 which is right where the consistent DMA area starts. To accommodate all static mappings on machines with possible highmem usage, the default vmalloc area size is changed to 240 MB so that VMALLOC_START is no higher than 0xf0000000 by default.

The purpose of this is _only_ to avoid a regression on an existing machine while a better fix is implemented. On shmobile the consistent DMA memory area was set to 158MB in commit 28f0721a79 with no explanation. The documented size for this area should vary between 2MB and 14MB, and none of the other ARM targets exceed that. The included #warning is therefore meant to be noisy on purpose to get shmobile maintainers attention and this commit reverted once this consistent DMA size conflict is resolved.
