I only did 1G of kernel low mem, so that there still would be space left for vmalloc mappings. I have a 8265 witch uses 0xf0000000 and up for internal stuff and flash, so with 1G lowmem and kernel baseadr set to 0xa.... I have 0xe0000000 to 0xeffffffff for virtual address space. I do not remember if I had to patch some other parts of the kernel also. I do not think I did. Can't chech right now either, because we used bitkeeper and I cannot even check the commit logs anymore.
