    Subject[PATCH 0/7] [GIT PULL] jump-labels: Implement 2 and 5 byte jumps


    A while ago I posted this series and you discovered a bug. I fixed that
    bug, but due to traveling and other responsibilities I'm not sure
    I posted the fix.

    The fix is the last patch in this series.

    As things have changed since the last post, there were a lot of conflicts,
    and I had to rebase the patch set against tip/perf/jump-labels and
    fix up the patches. Mostly the changes from JUMP_LABEL_* to STATIC_KEY_*.

    But I got this done and retested them.

    Steven Rostedt (7):
    x86/jump-label: Use best default nops for inital jump label calls
    x86/jump-label: Do not bother updating nops if they are correct
    x86/jump-label: Add safety checks to jump label conversions
    jump labels: Add infrastructure to update jump labels at compile time
    x86/jump labels: Use etiher 5 byte or 2 byte jumps
    x86/jump lables: Show where and what was wrong on errors
    x86/jump labels: Handle initialization of enabled nops
