Sierra and more then 64 cores

[Balamut]

Hi Fellas, hows everything?

 

I've been playing around with the different patches and was trying to remove the dreadful 64 core limit in the kernel.

 

Replacing 4883f93f with 4883f98f works until the crush on the AppleACPI, from what I can see this pattern:

ffffff80003f91a6	48 83 f9 3f 	cmpq	$0x3f, %rcx

found in 38 places in the kernel.

 

My question is, can any of you help me with figuring out how to change the 3f in this:

ffffff80003f91a6	cmpq	$0x3f, %rcx
