I also uploaded a clean build of gcc-12.1 with loongarch64 in the
https://mirrors.edge.kernel.org/pub/tools/crosstool/ builds.
I have not tried it yet.

Note: I have pulled in the generic ticket lock series into the asm-generic tree.
Please rebase your series on top of
git://git.kernel.org/pub/scm/linux/kernel/git/palmer/linux
generic-ticket-spinlocks-v6
to avoid duplicating the commits. As long as you are based on top of the
9282d0996936 commit, that should be fine.

I think with this you have addressed the comments that I had in the past.
Xuerui Wang and some others had additional comments that of course
need to be addressed, but this is looking good to me.
