I think I got everything from the v1 and v2, but it was a bit mixed up so sorry if I missed something. I'm generally being conservative on the tags here, as things have drifted around a bit. Specifically I dropped the Tested-bys, as this is all based on 5.18-rc1 now and there's been a touch of diff. I've put this at palmer/tspinlock-v3, in case that helps anyone. This generally looks good to me, but I'll wait for feedback before putting it anywhere else. I'd default to doing a shared tag for the asm-generic stuff and then let other arch folks pull in that (with their arch support), but if you want me to take it via my tree then feel free to just say so explicitly. What's on that branch right now definately shouldn't be treated as stable, though, as I'll wait for at least an official Ack/Review from the asm-generic folks (and of course there may be more feedback). This passes my standard tests, both as the whole thing and as just the RISC-V spinlock change. That's just QEMU, though, so it's not all that exciting. Changes since v2 <20220319035457.2214979-1-guoren@kernel.org>: * Picked up Peter's SOBs, which were posted on the v1. * Re-ordered the first two patches, as they * Re-worded the RISC-V qrwlock patch, as it was a bit mushy. I also added a blurb in the qrwlock's top comment about this dependency. * Picked up Stafford's fix for big-endian systems, which I have not tested as I don't have one (at least easily availiable, I think the BE MIPS systems are still in that pile in my garage). * Call the generic version , as there's really no utility to the version that only errors out. Changes since v1 <20220316232600.20419-1-palmer@rivosinc.com>: * Follow Arnd suggestion to make the patch series more generic. * Add csky in the series. * Combine RISC-V's two patches into one. * Modify openrisc's patch to suit the new generic version.
