Build fails for RISC-V with:

In file included from ./include/linux/pgtable.h:6,
                  from ./include/linux/mm.h:31,
                  from arch/riscv/kernel/asm-offsets.c:8:

Reverting 06536c4857271eeb19d76dbb4af989e2654a94e0 riscv: use an atomic 
xchg in pudp_huge_get_and_clear() fixes the build.

The problem is that this patch was already applied to 6.17 just before 
release, so the function pudp_huge_get_and_clear() ends up being 
duplicated in the file.
