stable backport for dc8635b78cd8669

[Vineet Gupta]

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
