This only complicates the code with no pratical gain: - In execbuffer this matters on for g33/pineview, as this is the only chip that needs fences and has an unmappable gtt area. But fences are only possible in the mappable part of the gtt, so need_fence implies need_mappable. And need_mappable is only set independantly with relocations which implies (for sane userspace) that the buffer is untiled. - The overlay code is only really used on i8xx, which doesn't have unmappable gtt. And it doesn't support tiled buffers, currently. - For all other buffers it's a bug to pass in a tiled bo. In short, this disdinction doesn't have any practical gain. I've also reverted mapping the overlay and context pages as possibly unmappable. It's not worth being overtly clever here, all the big gains from unmappable are for execbuf bos. Also add a comment for a clever optimization that confused me while reading the original patch by Chris Wilson.

This breaks the abi, eg: A double buffering mesa client might leave the last framebuffer in unmappable space on close. A subsequent glReadPix by a frontbuffer rendering client then goes boom. My pretty anal mappable/unmappable consistency checking detected this, see https://bugs.freedesktop.org/show_bug.cgi?id=31286 Chris Wilson tried to fix this in 085ce2643713830cf772c by pinning tiled framebuffers into mappable space. This a) renders the original optimization of not forcing framebuffers for pageflipping clients into mappable pointless because all our scanout buffers are tiled by default. b) doesn't solve the problem for untiled framebuffers. So kill this. Emperically it's no gain anyway because framebuffers are being reused by the ddx and hence there's no chance for them to get constanly bounced between mappable and unmappable.
