Yeah, so a full allyesconfig vmlinux gives ~22K .text size increase:
text data bss dec hex filename
85391772 105899159 70717440 262008371 f9dee33 vmlinux
before
85413991 105899223 70746112 262059326 f9eb53e vmlinux
after
--------
22219
I guess I better try the thunk stuff, might make it smaller.
Also, in the next version I'll split out the static_cpu_has() move into
a separate patch, as you requested on IRC.
Thanks.
