Hi Liam,
Would you consider renaming maple tree's "mt_init()" function to
maple_tree_init() or mtree_init() or something that does not
conflict with the mt_init() function in arch/mips/ so that
these build errors don't happen?
thanks.

Hello Randy,
I did address this when it occurred on the 24th [1]. I had looked at
this and was thinking I would rename the maple tree function, but
Matthew suggested renaming the mips function instead. I looked into the
conflict and the arch/mips/kernel/mips-mt.c uses the mips_ prefix for
almost all of the functions. So I generated a patch on my tree for
next-20220225 which fixes the issue by renaming the mips side of things.
Please see 51e773764d11 for the very small rename.
