This patch moves the DRM core's AGP code behind CONFIG_DRM_LEGACY. The only use besides legacy, UMS drivers is radeon, which can implement the required functionality by itself.
This patchset has no impact on the AGP support of existing drivers.
Patches 1 and 2 move some AGP code from DRM core into radeon. Radeon uses some of the AGP code for its internal purposes. But being a KMS driver, there's no reason why radeon should provide the rsp AGP ioctls. So duplicate the implementation in radeon and thus uncould it from the legacy code.
Patch 3 moves some AGP-related PCI helpers behind CONFIG_DRM_LEGACY.
Patch 4 moves DRM's AGP code behind CONFIG_DRM_LEGACY. The files are then only build when legacy drivers are active.
Built-tested with different config options selected.
