Subject: linux-next: build failure after merge of the loongarch tree

Hi all,

After merging the loongarch tree, today's linux-next build (x86_64
allmodconfig) failed like this:

Caused by commit

  0541f3fad39f ("LoongArch: Parse MADT to get multi-processor information")

I have used the loongarch tree from next-20220805 for today.
