found them looking for my V4L2 + mmap + MIPS solution... Is the

$ grep V4L2_BUF_FLAG_NO_CACHE_ * -r
Documentation/DocBook/media/v4l/io.xml: <entry><constant>V4L2_BUF_FLAG_NO_CACHE_INVALIDATE</constant></entry>
Documentation/DocBook/media/v4l/io.xml: <entry><constant>V4L2_BUF_FLAG_NO_CACHE_CLEAN</constant></entry>
Documentation/DocBook/media/v4l/vidioc-prepare-buf.xml:<constant>V4L2_BUF_FLAG_NO_CACHE_INVALIDATE</constant> and
Documentation/DocBook/media/v4l/vidioc-prepare-buf.xml:<constant>V4L2_BUF_FLAG_NO_CACHE_CLEAN</constant> flags to skip the respective
include/uapi/linux/videodev2.h:#define V4L2_BUF_FLAG_NO_CACHE_INVALIDATE 0x0800
include/uapi/linux/videodev2.h:#define V4L2_BUF_FLAG_NO_CACHE_CLEAN 0x1000
