From 0ed7a498f416dcfa1cca478a559238a2a3396240 Mon Sep 17 00:00:00 2001 From: Alexander van Heukelum Date: Wed, 22 Oct 2008 12:00:10 +0200 Subject: [PATCH] x86_64, dumpstack: move kexec_crash from __die to oops_end oops_end is preceded by either a call to __die, or a conditional call to crash_kexec. Move the conditional call to crash_kexec from the end of __die to the start of oops_end and remove the superfluous call to crash_kexec in die_nmi.
