Hi Stable team,
Can we please backport dc8635b78cd8669c37e230058d18c33af7451ab1 ("kernel/exit.c: export abort() to modules")
0-Day kernel test infra reports ARC 4.x.y builds failing after backport of af1be2e21203867cb958aace ("ARC: handle gcc generated __builtin_trap for older compiler")
Thx -Vineet

So is this only needed in 4.9.y and 4.4.y?
thanks,

Yes indeed !
It doesn't apply there at all, can you provide a working backport for those kernels so that I can queue it up?
thanks,

This is a custom patch (no mainline equivalent) for stable backport only to address 0-Day kernel test infra ARC 4.x.y builds errors.
The reason for this custom patch as that it is a single patch, touches only ARC, vs. atleast two 7c2c11b208be09c1, dc8635b78cd8669 which touch atleast 3 other arches (one long removed) and could potentially have a fallout.
