+Subject: [PATCH] arm64: fix SDEI stack frame unwind while UNW_4_14 is set
+
+Fix two bugs:
+  1) If BT_IRQSTACK is set, both irq_stack and sdei_normal_stack need
+     to be checked while switching to process stack.
+  2) Use bt->frameptr in arm64_unwind_frame() just like irq stack.

+Subject: [PATCH] Fix for 'sys' to properly display the PANIC message
+
+Using 'sys' command, we can view the panic message with general system
+information. If we run RISCV64-based vmcore, PANIC message is not properly
+displayed.
+
+The reason is that the string "Unable to handle kernel" is not
+completely matched with the panic_msg[]. The corresponding kernel commit
+is 21733cb518471.
+
+Without the patch:
