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.

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
