+Subject: [PATCH 1/2] Fix warning about kernel version inconsistency during
+ crash startup
+
+Currently, the symbol ".rodata" may not be found in some vmlinux, and
+the strings command will still be used to get the linux banner string,
+but this gets two strings as below:
+
+  # strings vmlinux | grep "Linux version"
+  Linux version 6.5.0-0.rc2.17.fc39.x86_64 ... GNU ld version 2.40-9.fc39) # SMP PREEMPT_DYNAMIC
+  Linux version 6.5.0-0.rc2.17.fc39.x86_64 ... GNU ld version 2.40-9.fc39) #1 SMP PREEMPT_DYNAMIC Mon Jul 17 14:57:35 UTC 2023
+
+In the verify_namelist(), the while-loop will only determine if the
+first linux banner string above matches and break the loop. But actually
+the second string above is correct one. Eventually, crash starts up with
+the following warning:
+
+  # ./crash -s vmlinux vmcore
+  WARNING: kernel version inconsistency between vmlinux and dumpfile
+
+  # ./crash -s
+  WARNING: kernel version inconsistency between vmlinux and live memory
+
+Let's always try to match the correct one, otherwise still prints a
+warning as before.

+Subject: [PATCH 2/2] Fix get_linux_banner_from_vmlinux() for vmlinux without
+ ".rodata" symbol
+
+As written in the previous patch, some recent kernels do not have the
+".rodata" symbol.  As a result, the get_linux_banner_from_vmlinux()
+returns FALSE and the slower fallback routine is used.
+
+Use "__start_rodata" symbol if the ".rodata" symbol is not available.
