Sorry for inaccessible links, I take the patch from ACPICA, and the
links here are intended to provide to ACPI maintainers when the patch
was submitted to ACPICA.

The ACPI spec 6.5 is not published yet, and I have asked the ACPI spec
work group, their reply is that I can not share the unpublished spec
draft link to the public, only using for member to review. I think
I can put the ECR(Engineering Change Request) file that described
LoongArch APICs on my github and put the link in the patch.

https://github.com/lvjianmin-loongson/acpica/blob/master/Add%20APIC%20Structures%20for%20Loongarch%20in%20MADT-rev3.pdf

From mail of the ACPI spec work group , the ACPI spec 6.5 will be
published in late July or early August.
