+From a5531b24750e7949c35640d996ea14c0587938bc Mon Sep 17 00:00:00 2001
+From: John Ogness <john.ogness@linutronix.de>
+Date: Fri, 20 Nov 2020 05:56:59 +0000
+Subject: [PATCH 1/2] printk: add support for lockless ringbuffer
+
+Linux 5.10 introduces a new lockless ringbuffer. The new ringbuffer
+is structured completely different to the previous iterations.
+Add support for dumping the ringbuffer with the "log" command.
+The new ringbuffer is detected based on the availability of
+the "prb" symbol.
+
+Upstream-Status: Backport [https://github.com/crash-utility/crash/commit/a5531b24750e7949c35640d996ea14c0587938bc]

+Date: Wed, 25 Nov 2020 05:27:53 +0106
+Subject: [PATCH 2/2] printk: use committed/finalized state values
+
+An addendum to the previous crash commit a5531b24750e.
+The ringbuffer entries use 2 state values (committed and finalized)
+rather than a single flag to represent being available for reading.
+Copy the definitions and state lookup function directly from the
+kernel source and use the new states.
