Therefore some other aspect of the change is causing problems and I
think that aspect is the size of the new code.
Actually, there is a way to prove that this is indeed the bug, Meelis
what does the entry for "swapper_tsb" say in your System.map file for
a failing kernel?
If it is not "0000000000408000", then that shows the bug.
I've run into this situation, and the assembler emits a warning that
looks like this:
arch/sparc/kernel/head_64.S:869: Warning: .space or .fill with negative
value, ignored
I've worked around it by moving some of the includes to after the ttable
include. I think this is ok as long as code doesn't get situated too far
away for the branch displacement to handle.
