Reverting the changes to x86-64's vmlinux.lds.S first introduced in
this patch is enough to get my box booting again.
- is this change necessary or can it be reverted for the time being?
- how to debug what's causing this? linker scripts aren't exactly my
cup of tea
- I'm going to try -mm now to see if this affects mainline as well.
Cheers,
Muli
