Arnd, can you check that with kasan please? (I don't have gcc 7.) For me the size diff against current git is

Sorry for the late reply.
I was rather sure that I had done the numbers and replied to you earlier, but I see no evidence of that, so here it comes again, using gcc-7 and kasan:
text data bss dec hex filename 2623339 511153 12064 3146556 30033c obj-x86/drivers/gpu/drm/i915/i915-original.o 2634886 511153 12064 3158103 303057 obj-x86/drivers/gpu/drm/i915/i915-linux-next.o 2617989 520561 12064 3150614 301316 obj-x86/drivers/gpu/drm/i915/i915-arndpatch.o
The first one is linux-next with ce64645d86ac ("drm/i915: use variadic macros and arrays to choose port/pipe based registers") reverted, the second one is the current version, and the third is with my patch applied on top.
