Subject: [PATCH] wire up oops_enter()/oops_exit()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=abf0f10948b316b577851ef21c728341f1046552;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[PATCH] wire up oops_enter()/oops_exit()

Implement pause_on_oops() on x86_64.

AK: I redid the patch to do the oops_enter/exit in the existing
oops_begin()/end(). This makes it much shorter.
