commit c674c77f69684bfa57e3c61d6dbf404c13953f34

    x86: don't open-code [gm]fn_to_[gm]addr()
    
    At least in pure address calculation use the intended basic construct
    instead of opend-coded left-shifting by PAGE_SHIFT. Leave alone page
    table entry calculations for now, as those aren't really calculating
    addresses.
    
    No functional change.

    x86/mm: drop gfn_to_paddr()
    
    This really is gfn_to_gaddr() in disguise; no need to have two variants
    of the same logic.

    x86: drop REX64_PREFIX
    
    While we didn't copy the full Linux commentary, Linux commit
    7180d4fb8308 ("x86_64: Fix 64bit FXSAVE encoding") is quite explicit
    about gas 2.16 supporting FXSAVEQ / FXRSTORQ. As that's presently our
    minimal required version, we can drop the workaround that was needed for
    yet older gas.

    Add libfuzzer target to fuzz/x86_instruction_emulator
    
    This target enables integration into oss-fuzz. Changing invalid input return
    to -1 as values other then 0/-1 are reserved by libfuzzer. Also adding the
    missing __wrap_vsnprintf wrapper which is required for successful oss-fuzz
    build.
