no no. So from a quick look I *assumed* you merged your v1 and revert of the
Steven's patch into one piece. But now I see that you don't disable preemption
64bit which means you revert upstream change.
Here is what happens:
- I drop your v2
- I merge your v1 with updated patch description
- I revert "x86: Do not disable preemption in int3 on 32bit". If someone
wants to skip the delayed signal on 32bit please address this upstream
first (that is skip the preempt_disable() on 32bit if it is not
required there).
- Yang Shi, please send a changelong if you send incremental patches.
Sebastian
