Ok, all of the following was with dim's version of the patch. I can
retry with your version too, but I don't think it will make a difference.=
The kernel works fine with gcc, but doesn't work compiled with clang.
Booting [/boot/kernel/kernel]...
jumping to kernel entry at 0xc0088000.
OF_panic: sparc64_init: cannot find boot CPU node
Program terminated
{1} ok
So, the same panic with your and dim's patch, compiled with clang.
Userland was compiled with gcc, cc is gcc and I used "CC=3Dclang make
kernel" to build the kernel with clang.
