sparc has failed to boot recently and I bisected it down to this patch:
 ...
 sparc: correct section of current_pc()
 ...
Reverting this patch gets current git booting again.
Thanks for tracking this down.  I'll take a look and if I
can't figure it out I'll revert.


Sorry, I will not have the time to look at it. But this bug is weird...

You can't change sections in the middle of a chunk of code. The code above current_pc: falls through to that label which is now in a different section. Thats why you get an illegal instruction trap at bootup.
