2020-10-13mm/memremap_pages: convert to 'struct range'Dan Williams
The 'struct resource' in 'struct dev_pagemap' is only used for holding resource span information. The other fields, 'name', 'flags', 'desc', 'parent', 'sibling', and 'child' are all unused wasted space. This is in preparation for introducing a multi-range extension of devm_memremap_pages(). The bulk of this change is unwinding all the places internal to libnvdimm that used 'struct resource' unnecessarily, and replacing instances of 'struct dev_pagemap'.res with 'struct dev_pagemap'.range. P2PDMA had a minor usage of the resource flags field, but only to report failures with "%pR". That is replaced with an open coded print of the range.

2020-09-11drm/ttm: nuke memory type flagsChristian König
It's not supported to specify more than one of those flags. So it never made sense to make this a flag in the first place. Nuke the flags and specify directly which memory type to use.

2020-09-09drm: allow limiting the scatter list size.Gerd Hoffmann
Add drm_device argument to drm_prime_pages_to_sg(), so we can call dma_max_mapping_size() to figure the segment size limit and call into __sg_alloc_table_from_pages() with the correct limit. This fixes virtio-gpu with sev. Possibly it'll fix other bugs too given that drm seems to totaly ignore segment size limits so far ... v2: place max_segment in drm driver not gem object. v3: move max_segment next to the other gem fields. v4: just use dma_max_mapping_size().

2020-09-03drm/nouveau: move io_reserve_lru handling into the driver v5Christian König
While working on TTM cleanups I've found that the io_reserve_lru used by Nouveau is actually not working at all. In general we should remove driver specific handling from the memory management, so this patch moves the io_reserve_lru handling into Nouveau instead. v2: don't call ttm_bo_unmap_virtual in nouveau_ttm_io_mem_reserve v3: rebased and use both base and offset in the check v4: fix small typos and test the patch v5: rebased and keep the mem.bus init in TTM.
