Thanks for looking at it. However, these warnings seem unrelated to my patchset. I didn't change any vga/fb headers nor did I touch arkfb/s3fb. Furthermore, I cannot reproduce these warnings. "vga_res" is a "struct resource", "->start" is of type "resource_size_t" which is typedef'ed to "phys_addr_t". Seems like the build-bot used some random config with CONFIG_PHYS_ADDR_T_64BIT set but building on 32bit (or something like that). Is there any place where I can see the compiler log? Or the used .config file?
