Subject: [PATCH] mm/vmalloc: Remove quoted string split across lines

A checkpatch.pl script complains on splitting a text across
lines. It is because if a user wants to find an entire string
he or she will not succeeded.

<snip>
WARNING: quoted string split across lines
+               "vmalloc size %lu allocation failure: "
+               "page order %u allocation failed",

total: 0 errors, 1 warnings, 10 lines checked
<snip>
