Subject: [PATCH 4.19 046/139] x86/speculation: Mark string arrays const correctly

4.19-stable 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.
