Subject: [PATCH 1/2] gma500: Add 2D acceleration

This is taken from Richard Purdie's previous attempt to rip the heart out
of the PVR driver and stake it.

Accelerate copies and fills.

[Revised patch which disables the methods until we can finish debugging them]

Subject: [PATCH 2/2] gma500: Rip out the memory manager

At this point we simply stuff the display at the start of the stolen memory
area that the BIOS gave us. No user framebuffers no multiple framebuffers.

However from here we have a better chance of seeing what is going on and
writing an actual gem manager for the driver.

This doesn't apply.

The 1/2 patch had some fuzz in the Makefile, which I fixed up by hand,
but it makes me think that you are diffing this against some different
tree.

Care to redo it and resend?

I've investigated this. The cause seems to be a patch

commit 5352161fc449d7a7573b2e13bd02162aae7aeb69

applied by yourself which cleaned up all sorts of random whitespace
noise and broke further patch application. Given that this is staging
and random whitespace is less important than actually fixing the code I
think the fix is to revert that commit and then apply mine.

Well, I did copy you on that patch, and let you know I made it, so this
type of thing wouldn't happen. I'll go fix it by just stripping out the
trailing whitespace from your patch :)

This doesn't seem to explain the Makefile difference in the 1/2 patch
though...

And I still don't think this is the issue.

Your patch removes two lines from drivers/staging/gma500/psb_drm.h with
the following diff:
--- a/drivers/staging/gma500/psb_drm.h
+++ b/drivers/staging/gma500/psb_drm.h

Yet those #defines are not present in this file right now. That's not a
whitespace change...

Still confused,

Need to sort some other drivers out but I'll send you the regenerated
patches in a bit once I'e pulled todays -next and see what is up. Makefile
one does seem odd as nothing else should be touching that area.

Missed the spaces patch first time around dunno where it went.
