Subject: [S390] Add oops_enter()/oops_exit() calls to die().
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bca0fb8683b7406d3056dc53a14b0a482c367e2b;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[S390] Add oops_enter()/oops_exit() calls to die().

This is mainly to switch off all potentially debugging stuff that
won't report anything useful after an oops happened.
Besided that setting pause_on_oops will work too, but doesn't make
too much sense on s390.
