Can you check if the patch helps:

diff --git a/arch/parisc/mm/fixmap.c b/arch/parisc/mm/fixmap.c
index cc15d737fda6..ae3493dae9dc 100644
(...)

Yes, everything's fine now. Applied on top of v6.5-rc4, there
were some offsets.

Now confirmed on top of 6.4.8 as well.

However, there's now an issue when reconfiguring the locales package in
Debian:

     Setting up locales (2.37-7) ...
     Generating locales (this might take a while)...
       C.UTF-8...cannot map archive header: Invalid argument
      done

Using 6.3.13, everything is fine.

There a Debian bug report #552233 from very old ages about this, the
solution suggests this is related to memory management so it might apply
here, too.

I'm afraid that my patch:
commit 32832a407a7178eec3215fad9b1a3298c14b0d69

    io_uring: Fix io_uring mmap() by using architecture-provided get_unmapped_area()

might be the culprit...
