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 76 bytes:

Before:
text data bss dec hex filename
4217 1540 128 5885 16fd arch/x86/platform/intel-mid/pwr.o

After:
text data bss dec hex filename
3981 1700 128 5809 16b1 arch/x86/platform/intel-mid/pwr.o
