No, no, no, kexec is not involved at all.
Here's the whole dmesg up until efi_enter_virtual_map. When we have entered
efi_enter_virtual_mode, the region has changed from
[ 0.000000] efi: mem11: type=4, attr=0xf, range=[0x000000007e0ad000-0x000000007e0cc000) (0MB)
to

And yes, I still need to audit whether the kernel actually does that
change. I'm still looking...
