No, but we can merge it together with the loongarch architecture for 5.19.
I suggested you coordinate with Guo Ren and Palmer Dabbelt about how to best merge it. The latest version was pasted two weeks ago [1], and it sounds like there are only minor issues to work out and that I can merge v4 into the asm-generic tree before merging the loongarch code in the same place.
