    Subject[RFC][PATCH 2/2] Generalize fd_set handling across architectures
    Generalize fd_set handling across architectures

    The fd_set handling is identical across all architectures, but each has its
    own unique set of ugly functions or macros to do it. This cleans up all of
    the ugliness and merges the duplicated code into a single KABI header,
    include/kabi/fdset.h, which is then included in the old places to preserve
    existing semantics.

    Appears to compile correctly with allmodconfig on powerpc (32-bit)
