This means, it passes in "vma->vm_start + page" in as the start
address.
Yet the last line, printed by the tracing code in io_remap_pfn_range()
is getting 0x71800000, when it should be 0x71802000.
I strongly believe your kernel is being miscompiled by whatever
gcc is being used to build your kernels.
Okey, good that there is something I can try and see. I'll see what a
rebuild does of the gcc 64bit and have as basic CFLAGS as possible doing
this and rebuild the kernel and see what happens, if not, I guess I'll
bugger the Gentoo Sparc guys again.
Thanks for the help.
