in arch/x86/kernel/early-quirk.c
and on top of https://git.kernel.org/cgit/linux/kernel/git/yinghai/linux-yinghai.git/commit/?h=for-x86-early-quirk-usb&id=de38757e964cfee20e6da1977572a2191d7f4aa0
You could add one entry in early_qrk[].
Some one already try to use that path to disable x2apic on some thinkpad.
So it should work on nointrremap too.
Thanks
