    To people running the development kernel, please note that commit
    e6e019a801e99ba7888ed009c5c3b3c7b047af1e requires a full world and kernel

    Most/all programs should still run.  Most pkgsrc programs should also
    still run without needing to be rebuilt.  However, several user-visible
    structures have changed size and any programs doing really fancy stuff
    with the signal stack state or with ucontext_t may break.

    This commit fixes floating point state corruption when any signal is taken.
    The bug was introduced on Jan 1 in master with the AVX work.

    RELEASE kernels are NOT affected.
