+Subject: [PATCH] powerpc: add missing NULL terminator to avoid boot panic on
+ PPC40x
+
+The missing NULL terminator can cause a panic on
+PPC405 boards during boot:
+
+ Linux/PowerPC load: console=ttyS0,115200 root=/dev/mtdblock1 rootfstype=squashfs,jffs2 noinitrd init=/etc/preinit
+ Finalizing device tree... flat tree at 0x6a5160
+ bootconsole [udbg0] enabled
+ Page fault in user mode with in_atomic() = 1 mm = (null)
+ NIP = c0275f50 MSR = fffffffe
+ Oops: Weird page fault, sig: 11 [#1]
+ PowerPC 40x Platform
+ Modules linked in:
+ NIP: c0275f50 LR: c0275f60 CTR: c0280000
+ REGS: c0275eb0 TRAP: 636f7265 Not tainted (3.7.1)
+ MSR: fffffffe <VEC,VSX,EE,PR,FP,ME,SE,BE,IR,DR,PMM,RI> CR: c06a6190 XER: 00000001
+ TASK = c02662a8[0] 'swapper' THREAD: c0274000
+ GPR00: c0275ec0 c000c658 c027c4bf 00000000 c0275ee0 c000a0ec c020a1a8 c020a1f0
+ GPR08: c020f631 c020f404 c025f078 c025f080 c0275f10
+ Call Trace:
+ ---[ end trace 31fd0ba7d8756001 ]---
+
+ Kernel panic - not syncing: Attempted to kill the idle task!
+
+The panic happens since commit 9597abe00c1bab2aedce6b49866bf6d1e81c9eed
+(sections: fix section conflicts in arch/powerpc), however the root
+cause of this is that the NULL terminator were not added in commit
+a4f740cf33f7f6c164bbde3c0cdbcc77b0c4997c (of/flattree: Add of_flat_dt_match()
+helper function).
