From: Colin Ian King <colin.king@canonical.com>
Don't populate const array ver_list on the stack, instead make it static. Makes the object code smaller by over 400 bytes:
Before: text data bss dec hex filename 18444 3168 320 21932 55ac drivers/net/hyperv/netvsc.o
After: text data bss dec hex filename 17950 3224 320 21494 53f6 drivers/net/hyperv/netvsc.o
(gcc 6.3.0, x86-64)
