    Subject[PATCH 0/9] x86,objtool: Optimize !RETPOLINE
    Hi,

    Now that Juergen's paravirt rework, which included the negative alternative
    stuff, landed in tip, here's a respin of my retpoline patches.

    The main feature is replacing the compiler generated (tail) calls to
    __x86_indirect_thunk_\reg with an ALTERNATIVE that replaces them with regular
    indirect call instructions, eliding the double jump.

    Patches rely on tip/objtool/core and tip/x86/alternatives
