X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f18046f7a50accf76dab9c6ab274a7e38143a0dc;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

kernel/exit.c: export abort() to modules

commit dc8635b78cd8669c37e230058d18c33af7451ab1 upstream.

gcc -fisolate-erroneous-paths-dereference can generate calls to abort()
from modular code too.
