The changes since v5 have been very minor, just some tags and a few wording changes to the qspinlock comment. There's also a PR for Arnd's tree, assuming that lands I'll take the RISC-V bits into my tree and assuming the csky and openrisc folks don't say anything I'll take those too (though now that we're got a multi-tree merge going that doesn't matter so much, but I said I'd take them so I'm going to default to that as everyone else may have tuned out). Changes since v4 <20220430153626.30660-1-palmer@xxxxxxxxxxxx>: * Some wording cleanups for the qspinlock comment. * Collected reviewed/tested tags. Changes since v3 <20220414220214.24556-1-palmer@xxxxxxxxxxxx>: * Added a smp_mb() in the lock slow-path, to make sure that is RCsc. * Fixed the header guards. Changes since v2 <20220319035457.2214979-1-guoren@xxxxxxxxxx>: * 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 <asm-genenic/spinlock{_types}.h>, as there's really no utility to the version that only errors out. Changes since v1 <20220316232600.20419-1-palmer@xxxxxxxxxxxx>: * 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.
