Subject[PATCH] cpufreq: speedstep-lib: make several arrays static, makes code smaller
Date
From: Colin Ian King <colin.king@canonical.com>

Don't populate arrays on the stack, instead make them static.
Makes the object code smaller by over 860 bytes:

Before:
text data bss dec hex filename
10716 5196 0 15912 3e28 drivers/cpufreq/speedstep-lib.o

After:
text data bss dec hex filename
9690 5356 0 15046 3ac6 drivers/cpufreq/speedstep-lib.o
