The sequence for replacing the scanout buffer is much shorter than a

speeds up cases where only a new framebuffer is to be scanned out.

I think "hardware cursor" has specific meaning for Tegra(e.g: Tegra30
has a 32x32 24bpp or 64x64 2bpp hardware cursor). So

Hi Terje,
Here is the second part comments. I admit I still haven't finished
reading the codes... really too many codes. :)
Anyway I'll keep doing this when I have free slots.

Hi Terje,
I applied your patches on top of upstream 1224 kernel. Then I read the
codes. So here is my review comments(I use "git diff" to print out,
check below). I admit it's easy for me to not need to find the
corresponding lines in your 8 patch mails, but I've no idea whether it
is ok for you.

We must forget about that. I believe no one read the header files while
review. So thanks. :)
