I get:

since CONFIG_AGB_ARB is not being selected. Make I915 driver select it as the numerous other things it selects.

This is on latest Linus git (v2.6.36-rc2-237-gd4348c6) after doing `make oldconfig' on an Acer Aspire One netbook.

I reported this build failure here:

http://lkml.org/lkml/2010/8/23/127

Is there no other way to fix this? From the Kconfig description of VGA_ARB I thought I would not need this (and it's a new thing too), so why make my kernel bigger so easily?

<linux/vgaarb.h> should define dummy inline functions if CONFIG_VGA_ARB is not defined. It already does this for vga_client_register() but should cover the other functions as well.
