Linus Torvalds 4c388a8e74 zstd fixes for v5.16-rc1 
Fix stack usage on parisc & improve code size bloat
 
 This PR contains 3 commits:
 
 1. Fixes a minor unused variable warning reported by Kernel test robot [0].
 2. Improves the reported code bloat (-88KB / 374KB) [1] by outlining
    some functions that are unlikely to be used in performance sensitive
    workloads.
 3. Fixes the reported excess stack usage on parisc [2] by removing -O3
    from zstd's compilation flags. -O3 triggered bugs in the hppa-linux-gnu
    gcc-8 compiler. -O2 performance is acceptable: neutral compression,
    about -1% decompression speed. We also reduce code bloat
    (-105KB / 374KB).
 
 After this commit our code bloat is cut from 374KB to 105KB with gcc-11.
 If we wanted to cut the remaining 105KB we'd likely have to trade
 signicant performance, so I want to say that this is enough for now.
 
 We should be able to get further gains without sacrificing speed, but
 that will take some significant optimization effort, and isn't suitable
 for a quick fix. I've opened an upstream issue [3] to track the code size,
 and try to avoid future regressions, and improve it in the long term.
