+Subject: [PATCH] x86_64: x86_64 add crashdump trigger points
+
+o Start booting into the capture kernel after an Oops if system is in a
+  unrecoverable state. System will boot into the capture kernel, if one is
+  pre-loaded by the user, and capture the kernel core dump.
+
+o One of the following conditions should be true to trigger the booting of
+  capture kernel.
+        - panic_on_oops is set.
+        - pid of current thread is 0
+        - pid of current thread is 1
+        - Oops happened inside interrupt context.
