2017-11-02	drm/nouveau/mmu/gp100,gp10b: implement new vmm backend	Ben Skeggs	1	-0/+13
	Adds support for: - 64KiB/2MiB big page sizes (128KiB not supported by HW with new PT layout). - System-memory PTs. - LPTE "invalid" state. - (Tegra) Use of video memory aperture. - Sparse PDEs/PTEs. - Additional blocklinear kinds. - 49-bit address-space. GP100 supports an entirely new 5-level page table layout that provides an expanded 49-bit address-space. It also supports the layout present on previous generations, which we've been making do with until now. This commit implements support for the new layout, and enables it by default.

2017-11-02	drm/nouveau/mmu/gp100,gp10b: implement vmm on top of new base	Ben Skeggs	1	-0/+8
	Adds support for: - Selection of old/new-style page table layout (GP100MmuLayout=0/1). - System-memory PDs. New layout disabled by default for the moment, as we don't have a backend that can handle it yet. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
