[Andrew Morton]

The quilt patch titled
     Subject: LoongArch/tlb: fix "error: parameter 'ptep' set but not used" due to __tlb_remove_tlb_entry()
has been removed from the -mm tree.  Its filename was
     loongarch-tlb-fix-error-parameter-ptep-set-but-not-used-due-to-__tlb_remove_tlb_entry.patch

This patch was dropped because it was merged into the mm-nonmm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: LoongArch/tlb: fix "error: parameter 'ptep' set but not used" due to __tlb_remove_tlb_entry()

With LLVM=1 and W=1 we get:

  ./include/asm-generic/tlb.h:629:10: error: parameter 'ptep' set
  but not used [-Werror,-Wunused-but-set-parameter]

We fixed a similar issue via Arnd in the introducing commit, missed the
loongarch variant. Turns out, there is no need for loongarch to have a
custom variant, so let's just drop it and rely on the asm-generic one.
