video (VGA) object-files unconditionally built/included?

[Dag Bakke]

Hi.

I am putting together a tiny kernel for an embedded x86 target. Space is
tight, so I try to shave every kB I can get rid of.
I don't have anything resembling VGA or graphics, and my .config
reflects that. (Serial console.)

Yet, when building the kernel I see:

  LZMA    arch/x86/boot/compressed/vmlinux.bin.lzma
  CC      arch/x86/boot/video.o
  CC      arch/x86/boot/video-mode.o
  CC      arch/x86/boot/version.o
  CC      arch/x86/boot/video-vga.o
  CC      arch/x86/boot/video-vesa.o
  CC      arch/x86/boot/video-bios.o

# strings arch/x86/boot/bzImage | egrep -i 'vesa|vga|bios|mode'
+VESA
0123456789ABCDEFPress <ENTER> to see video modes available, <SPACE> to
continue, or wait 30 sec
Mode: Resolution:  Type:
Enter a video mode or "scan" to scan for additional modes:
Undefined video mode number: %x
VESA
BIOS


The video* objects sums up to 87kB. Can I get rid of that somehow? I am
using current git.

This is my .config:

Cc: is appreciated.
