When reviewing <https://lore.kernel.org/r/20221029084715.3669204-1-tongtiangen@xxxxxxxxxx> I noticed that the arch-specific VM_FAULT flags used by arm and s390 alias with VM_FAULT_HINDEX_MASK. I'm not sure if it's possible to manifest this as a bug, but it certainly seems fragile. The RISC-V patch is on top of the linked patch above, which isn't in any proper tree yet. Everything else should apply to 6.1-rc1, but I'm in no particular rush to get that cleanup in so rush on my end for 6.2. That said I figured it would be easier to send along this now, just in case someone who knows the MM code better thinks it can manifest as a bug.
Just pinging this one, I'm not sure if it was just bad timing on the last one. That RISC-V patch is still sitting around outside my tree.
