Ok, I'm at a bit of a loss... When I look at the assembly before and
after the patch, it looks pretty much the same. Additionally, the
function where the undefined exception occurs (caam_jr_interrupt())
doesn't make any use of wr_reg64 or rd_reg64 which is the only thing the
patch changes...
Also, it looks like the nonatomic headers are doing what they are
supposed to on this arch and generating two 32-bit ios and not a 64 bit one.
So I have no idea what's going on here... Are we sure this is the patch
causing the problem? Did you bisect?
Thanks,
Logan
