Subject: [PATCH 3.16 45/86] x86/speculation: Mark string arrays const
 correctly

3.16.68-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Thomas Gleixner <tglx@...utronix.de>

commit 8770709f411763884535662744a3786a1806afd3 upstream.

checkpatch.pl muttered when reshuffling the code:
 WARNING: static const char * array should probably be static const char * const

Fix up all the string arrays.
