Reviewed-by: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx> It's still on the low hanging fruit list for reducing our bloat. Ideas? i915_pcidata.ko? How far could we go with that, make all gen specific code a separate section and unload them after init?
There is one maybe easy win with DMI_MATCH business. It modpost was taught to handle string relocs, one could remove the hardcoded string storage of 4x79 bytes for every DMI_MATCH entry. We have one large-ish table which is not __initconst in intel_no_lvds, but I haven't looked at the rest of the kernel - if all other users are mostly __initconst then the saving wouldn't be that universally interesting.
One larger code re-org could be to move all genX prefixed functions into separate .kos and load them dynamically. But it is very difficult to estimate the saving given how much re-use we have. And the extraction would probably be quite messy.
