Date: Fri, 2 Dec 2022 19:03:51 -0800 From: Palmer Dabbelt <palmer@...osinc.com> To: linux-kernel@...r.kernel.org, linux-riscv@...ts.infradead.org, linux-s390@...r.kernel.org, linux-arm-kernel@...ts.infradead.org Subject: [PATCH 0/5] mm: Stop alaising VM_FAULT_HINDEX_MASK in arch code When reviewing <https://lore.kernel.org/r/20221029084715.3669204-1-tongtiangen@huawei.com> 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.
