Hi Ben (and others)

I tried this on a ThinkPad X230 (Ivy Bridge CPU, i7 3520M, so pcid but not
invpcid) on full UEFI mode and it doesn't boot at all. grub-efi loads the
kernel and initrd, but I don't have any message after “Loading initial
ramdisk” (even with debug earlyprintk=vga).

I've also tried with nopcid/pcid=no but it doesn't change anything.

I've tried maxcpus=1 and it does work so maybe backporting 375074cc736a could
help (I can take a look today).
