I was happy to try this patch on my 4Kec board with memory starting at
0x10000000 but it doesn't work.
Setting PHYS_OFFSET to 0, I get the expected "Wasting 2098176 bytes for
tracking 65568 unused pages" and everything works as usual.
Setting PHYS_OFFSET to 0x10000000, I get "Wasting 1024 bytes for
tracking 32 unused pages", but the kernel doesn't boot and crash in
init_bootmem_node().
Looking at phys_to_virt(), it looks like I also need to change
PAGE_OFFSET to 0x90000000 to get correct values. This makes the kernel
boot with a correct memory map, but userspace doesn't work anymore.
Just in case, I'm not using git head, but a 2.6.20 kernel with the 2
patches applied. Just tell me if you need complete dmesg.
