Applied. Thanks a lot. Please address John's request in a followup and these few issues: - rst doesn't look correct. Example: rst2man Documentation/networking/filter.rst >/dev/null Documentation/networking/filter.rst:1053: (WARNING/2) Inline emphasis start-string without end-string. > Except ``BPF_ADD`` _without_ ``BPF_FETCH`` (for legacy reasons), all 4 byte > atomic operations require alu32 mode. Clang enables this mode by default in > architecture v3 (``-mcpu=v3``). For older versions it can be enabled with > ``-Xclang -target-feature -Xclang +alu32``. It reads confusing to me. I would rephrase 'clang enables this mode by default' into 'clang can generate new atomic instruction when -mcpu=v3 is enabled'. 'For older versions...' This part I didn't get. The users need clang 12 that is capable to emit these insns. What 'older versions' you're talking about?
