Thanks for the recognition from both of you; it is my honor and pleasure 
to contribute to the LoongArch port and to Linux in general.

As I'm still not entirely satisfied with my kernel development skills, 
plus my day job is not kernel-related nor Loongson/LoongArch-related at 
all, listing me as reviewer should be enough for now. I will take care 
of the arch as long as I have the hardware.

BTW, there were already several breakages when rebasing the previous 
revision (I believe it's commit 215da6d2dac0 ("MAINTAINERS: Add 
maintainer information for LoongArch")) on top of linus' tree. Now I see 
the loongarch-next HEAD is already rebased on top of what I believe to 
be the current main branch, however I vaguely remember that it's not 
good to base one's patches on top of "some random commit", so I wonder 
whether the current branch state is appropriate for a PR?
