[PATCH 0/4] drm: Mark DRM's AGP code as legacy

[Thomas Zimmermann]

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.
