Subject: [REGRESSION] "UEFI: Don't pass boot services regions to SetVirtualAddressMap()" breaks macbook efi boot

Hey,

It seems that in the merge window my macbook pro stopped working at some point. I looked for suspicious
efi related commits, and found that reverting commit 1acba98f810a14b1255e34bc620594f83de37e36 worked,
letting my macbook pro boot succesfully.

Is there anything I can do to help diagnose this issue?

Thanks for the report. I'm going to queue up a revert of this patch,
Dave Young also reported a problem on his thinkpad.

Well bother. Yeah, reverting this is the right thing to do for now -
I'll spend some time looking into it more closely later in the week.
